Jo-Philipp Wich 77e2bccde8 ramips: only limit lzma dictionary size on mt7621
The changed dictionary size leads to a different LZMA header which breaks
sysupgrade image magic checkibng on at least some RT288x boards.

Since the commit message only mentions testing on MT7621 and since the
change appears to break at least one other ramips subtarget, do not take
any chances and restrict the size limitation to only MT7621.

Fixes FS#1797
Fixes 09b6755946 ("ramips: limit dictionary size for lzma compression")

Daniel Gimpelevich 1d3ea7874d ramips: fix BR-6478ACv2 support
The wholesale changes introduced in commit f9b8328 missed this DTS file
because it hadn't been merged yet. This patch brings it in line to match
the other mt7620a devices' DTS files.

Additionally, the Internet LED is now labeled correctly and set to unused
by default, since the WAN interface is not known in every configuration.

Using sysupgrade between images before and after this commit will require

Peter Lundkvist 33321ebefa ramips: TP-Link TL-WR902AC v3: don't build factory image
The line that produces factory image was accidentally left by me while
testing before inital commit.

I came to the conclusion that flashing from OEM firmware does not work
(seems to share this behavior with other tplinks based on mt7628).

I have not done any further analysis, as I was unable to open the
case and attach a serial port (too much glue). Maybe i will try once
more.

So the way to do initial flashing (or un-bricking) is to use the
tftp-recover image. It is possible to revert to OEM firmware with tftp
recovery; in this case the first 512 bytes the image file need to be
cut off.

INAGAKI Hiroshi 0b83a23560 ramips: add support for I-O DATA WN-AX1167GR
I-O DATA WN-AX1167GR is a 2.4/5 GHz band 11ac router, based on
MediaTek MT7621A.

Specification:

- MT7621A (2-Cores, 4-Threads)
- 64 MB of RAM (DDR2)
- 16 MB of Flash (SPI)
- 2T2R 2.4/5 GHz
- 5x 10/100/1000 Mbps Ethernet
- 2x LEDs, 4x keys (2x buttons, 1x slide switch)
- UART header on PCB
  - Vcc, GND, TX, RX from ethernet port side
  - baudrate: 115200 bps (U-Boot, OpenWrt)

Stock firmware:

In the stock firmware, WN-AX1167GR has two os images each composed of
Linux kernel and rootfs.
These images are stored in "Kernel" and "app" partition of the
following partitions, respectively.

(excerpt from dmesg):

MX25L12805D(c2 2018c220) (16384 Kbytes)
mtd .name = raspi, .size = 0x01000000 (16M) .erasesize = 0x00010000 (64K) .numeraseregions = 0
Creating 10 MTD partitions on "raspi":
0x000000000000-0x000001000000 : "ALL"
0x000000000000-0x000000030000 : "Bootloader"
0x000000030000-0x000000040000 : "Config "
0x000000040000-0x000000050000 : "Factory"
0x000000050000-0x000000060000 : "iNIC_rf"
0x000000060000-0x0000007e0000 : "Kernel"

0x000000fa0000-0x000000fb0000 : "backup"
0x000000fb0000-0x000001000000 : "storage"

The flag for boot partition is stored in "Key" partition, and U-Boot
reads this and determines the partition to boot.

If the image that U-Boot first reads according to the flag is
"Bad Magic Number", U-Boot then tries to boot from the other image.
If the second image is correct, change the flag to the number
corresponding to that image and boot from that image.

(example):

## Booting image at bc800000 ...
Bad Magic Number,FFFFFFFF
Boot from KERNEL 1  !!
## Booting image at bc060000 ...
   Image Name:   MIPS OpenWrt Linux-4.14.50
   Image Type:   MIPS Linux kernel Image (lzma compressed)
   Data Size:    1865917 Bytes = 1.8 MB
   Load Address: 80001000
   Entry Point:  80001000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK
raspi_erase_write: offs:f90000, count:34
.
.
Done!

Starting kernel ...

Flash instruction using factory image:

1. Connect the computer to the LAN port of WN-AX1167GR
2. Connect power cable to WN-AX1167GR and turn on it
3. Access to "192.168.0.1" on the web browser and open firmware

4. Select the OpenWrt factory image and perform firmware update
5. On the initramfs image, execute "mtd erase firmware" to erase stock
firmware and execute sysupgrade with sysupgrade image for WN-AX1167GR

Tobias Schramm faf64056dd ramips: add support for MikroTik RouterBOARD RBM11g
This commit adds support for the MikroTik RouterBOARD RBM11g.

=Hardware=

The RBM11g is a mt7621 based device featuring one GbE port and one
miniPCIe slot with a sim card socket and USB 2.0.

==Switch==

The single onboard Ethernet port is connected the CPU directly.
The internal switch of the mt7621 SoC is disabled.

==Flash==

The device has one spi nor flash chip. It is a 128 Mbit winbond 25Q128FVS
connected to CS0.

==PCIe==

The board features a single miniPCIe slot. It has a dedicated mini SIM
socket and a USB 2.0 port. Power to the miniPCIe slot is controlled via
GPIO9.

==USB==

There are no external USB ports.

==Power==

The board can accept both, passive PoE and external power via a 2.1 mm
barrel jack (center-positive). The input voltage range is 11-32 V.

==Serial port==

The device does have an onboard UART on an unpopulated header next to the
flash chip:

GND: pin 2
 TX: pin 7
 RX: pin 6

Settings: 115200, 8N1

See below illustration for positioning of the header.

0 = screw hole
* = some pin
T = TX  pin
R = RX  pin
G = GND pin

+---------------------

=Installation=

To install an OpenWRT image to the device two components must be built:

1. A openwrt initramfs image
2. A openwrt sysupgrade image

===initramfs & sysupgrade image===

Select target devices "Mikrotik RBM11G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin" in the
output directory.

==Installing==

**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the
created license file.**

When rebooted the board will try booting via ethernet first. If your
board does not boot via ethernet automatically you will have to attach
to the serial port and set ethernet as boot device within RouterBOOT.

1. Set up a dhcp server that points the bootfile to tftp server serving
   the "openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin"
   initramfs image
2. Connect to ethernet port on board
3. Power on the board
4. Wait for OpenWrt to boot

Right now OpenWrt will be running with a SSH server listening. Now
OpenWrt must be flashed to the devices flash:

1. Copy "openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin"
   to the device using scp.
2. Write openwrt to flash using "sysupgrade
   openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin"

Once the flashing completes the board will reboot. Disconnect from the
devices ethernet port or stop the DHCP/TFTP server to prevent the device
from booting via ethernet again.
The device should now boot straight to OpenWrt.

In some cases, recent builds fail to boot from flash with at least some
MT7621 based devices. The error message is:
"LZMA ERROR 1 - must RESET board to recover"
Booting the same kernel via TFTP works for some reason.

Through testing I figured out that limiting the LZMA dictionary size

Franz Flasch 8375623a06 ramips: add support for TP-Link Archer C2
Specification:

- System-On-Chip: MT7620A
- CPU/Speed: 580 MHz
- Flash-Chip: Winbond 25Q64BVSIG
- Flash size: 8192 KiB
- RAM: 64 MiB
- Wireless No1: SoC-integrated: MT7620A 2.4GHz 802.11bgn
- Wireless No2: On-board chip: MT7610EN 5GHz 802.11ac
- Switch: RTL8367RB Gigabit Switch
- USB: Yes 1 x 2.0

Preparing a TFTP recovery image for initial flashing:

Currently the only method to install openwrt for the first time is via
TFTP download in u-boot. After first install you can use regular updates.
WARNING: This method also overwrites the bootloader partition!

Create a TFTP recovery image:

1) Download a stock TP-Link Firmware file here:
     https://www.tp-link.com/en/download/Archer-C2_V1.html#Firmware
2) Extract u-boot from the binary file:
     #> dd if=c2v1_stock_firmware.bin of=c2v1_uboot.bin bs=1 skip=512 count=131072
3) Now merge the sysupgrade image and the u-boot into one binary:
     #> cat c2v1_uboot.bin openwrt-squashfs-sysupgrade.bin > ArcherC2V1_tp_recovery.bin

The resulting image can be flashed via TFTP recovery mode.

Flash instructions:

1) To flash the recovery image, start a TFTP server from IP address
   192.168.0.66 and serve the recovery image named
   ArcherC2V1_tp_recovery.bin.
2) Connect your device to the LAN port, then press the WPS/Reset button

- UART: 1 x UART on PCB - 57600 8N1

Flash instruction:
The U-boot is based on Ralink SDK so we can flash the firmware using UART:
1. Configure PC with a static IP address and setup an TFTP server.
2. Put the firmware into the tftp directory.
3. Connect the UART line as described on the PCB.
4. Power up the device and press 2, follow the instruction to
   set device and tftp server IP address and input the firmware
   file name. U-boot will then load the firmware and write it into
   the flash.

Tobias Schramm 5684d08741 ramips: Add support for Mikrotik RouterBOARD RBM33g
This commit adds support for the Mikrotik RouterBOARD RBM33g.

=Hardware=

The RBM33g is a mt7621 based device featuring three gigabit ports, 2
miniPCIe slots with sim card sockets, 1 M.2 slot, 1 USB 3.0 port and a male
onboard RS-232 serial port. Additionally there are a lot of accessible
GPIO ports and additional buses like i2c, mdio, spi and uart.

==Switch==

The three Ethernet ports are all connected to the internal switch of the
mt7621 SoC:

port 0: Ethernet Port next to barrel jack with PoE printed on it
port 1: Innermost Ethernet Port on opposite side of RS-232 port
port 2: Outermost Ethernet Port on opposite side of RS-232 port
port 6: CPU

==Flash==

The device has two spi flash chips. The first flash chips is rather small
(512 kB), connected to CS0 by default and contains only the RouterBOOT
bootloader and some factory information (e.g. mac address).
The second chip has a size of 16 MB, is by default connected to CS1 and
contains the firmware image.

==PCIe==

The board features three PCIe-enabled slots. Two of them are miniPCIe
slots (PCIe0, PCIe1) and one is a M.2 (Key M) slot (PCIe2).
Each of the miniPCIe slots is connected to a dedicated mini SIM socket
on the back of the board.

Power to all three PCIe-enabled slots is controlled via GPIOs on the
mt7621 SoC:

PCIe0: GPIO9
PCIe1: GPIO10
PCIe2: GPIO11

==USB==

The board has one external USB 3.0 port at the rear. Additionally PCIe
port 0 has a permanently enabled USB interface. PCIe slot 1 shares its
USB interface with the rear USB port. Thus only either the rear USB port
or the USB interface of PCIe slot 1 can be active at the same time. The
jumper next to the rear USB port controls which one is active:

open: USB on PCIe 1 is active
closed: USB on rear USB port is active

==Power==

The board can accept both, passive PoE and external power via a 2.1 mm
barrel jack. The input voltage range is 11-32 V.

=Installation=

==Prerequisites==

A USB -> RS-232 Adapter and a null modem cable are required for
installation.

To install an OpenWRT image to the device two components must be built:

1. A openwrt initramfs image
2. A openwrt sysupgrade image

===initramfs & sysupgrade image===

Select target devices "Mikrotik RBM33G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" in the output
directory.

==Installing==

**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the created
license file.**

Serial settings: 115200 8N1

The installation is a two-step process. First the
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" must be booted
via tftp:

1. Set up a dhcp server that points the bootfile to tftp server serving
   the "openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin"
   initramfs image
2. Connect to WAN port (left side, next to sys-LED and power indicator)
3. Connect to serial port of board
4. Power on board and enter RouterBOOT setup menu
5. Set boot device to "boot over ethernet"
6. Set boot protocol to "dhcp protocol" (can be omitted if DHCP server
   allows dynamic bootp)
6. Save config
7. Wait for board to boot via Ethernet

On the serial port you should now be presented with the OpenWRT boot log.
The next steps will install OpenWRT persistently.

1. Copy "openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" to the device
   using scp.
2. Write openwrt to flash using "sysupgrade
   openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin"

Once the flashing completes reboot the router and let it boot from flash.
It should boot straight to OpenWRT.

Giuseppe Lippolis 1680ae7eae ramips: add dwr-512 jboot firmware configuration
The previous fw version require the replacement of the stock bootloader
with u-boot. This prevent an easy stock restore of the original fw.

Now a proper fw util has been developed to manage the stock jboot
bootloader. Therefore make sense have a fw image for the stock
bootloader.

The old fw configuration (u-boot) is not compatible with the new one
and will not be supported anymore.

So at the end 2 image can be generated:

1) factory image with jboot bootloader
     openwrt-ramips-rt305x-dwr-512-b-squashfs-factory.bin
2) sysupgrade image with jboot bootloader

Mathias Kresin cb741654e5 ramips: improve GnuBee Personal Cloud Two support
Use the generic board detection for the GnuBee Personal Cloud Two
instead of the target specific one as all recent additions are doing.

Fixup the pinmux to set all pins used as GPIO to the function GPIO.
Request pins where used.

Drop the i2c from the dts. There is nothing connected. While at it fix an
indentation issue and use references instead of duplicating the whole
node path.

Use the same switch config as for the GB-PC1 and drop the led trigger for

Rosen Penev c60a21532b ramips: Add support for the GnuBee Personal Cloud Two
The GnuBee Personal Cloud Two crowdfunded on https://www.crowdsupply.com
It is a low-cost, low-power, network-attached storage device.

Specifications:

- SoC: MediaTek MT7621AT
- RAM: DDR3 512 MB
- Flash: 32 MB
- Six SATA ports for 3.5" Drives
- One SDcard
- One USB 3.0
- Two USB 2.0
- Gigabit Ethernet: Three Ports
- UART 3.5mm Audio Jack or 3 pin header - 57600 8N1
- Three GPIOs available on a pin header

Flash instructions:

The GnuBee Personal Cloud Two ships with libreCMC installed.
libreCMC is a Free Software Foundation approved fork of LEDE/OpenWrt.
As such one can upgrade using the webinterface or sysupgrade.

Das U-Boot has multiple options for recovery or updates including :

- USB
- http
- tftp

Errata:
- While there are three ethernet ports, the third requires support for
  the second GMAC. This will come in kernel 4.14.
- The first hard drive slot has a clearance issue with the two fan
  headers. Workaround is to pull the headers out and connect the pins to
  jumper wires.
- Using this device as a NAS is problematic with the 4.9 kernel as many
  /dev/sdX reads throw silent errors. The current theory behind this is
  some kind of unhandled DMA mapping error in the kernel. This is not an
  issue with kernel 4.4.

Jackson Ming Hu c0e131b436 ramips: add support for newifi d2
Previously Newifi D2 could only use PandoraBox M1's firmware.
It works fine, but LED GPIO is different.
As a result, a separated DTS file for this device should be implemented.

Hardware spec:

* CPU: MTK MT7621A
* RAM: 512MB
* ROM: 32MB SPI Flash
* WiFi: MTK MT7603+MT7612
* Button: 2 buttons (reset, wps)
* LED: 3 single-color LEDs (USB, WiFi 2.4GHz, WiFi 5GHz) &
       2 dual-color LEDs (Power, Internet)
* Ethernet: 5 ports, 4 LAN + 1 WAN

Installation method:

Same as Newifi D1, users may need to request unlock code from the device
manufacturer. Otherwise, a SPI flash programmer may be necessary to get
the firmware flashed. After the device is unlocked, press and hold reset
button before power cable plugs in. Then go to http://192.168.1.1 to
upload and flash the firmware package.

Andrew Crawley fe6f298b07 ramips: add support for Vonets VAR11N-300
The VAR11N-300 is a tiny wireless-N device with a hardwired Ethernet
cable, one extra Ethernet port, and an internal antenna, based on the
MediaTek MT7620n chipset.

Specs:
- MT7620n WiSoC @ 600MHz
- 32 MB SDRAM
- 4 MB SPI flash
- 2T2R 2.4GHz WiFi-N
- 1 attached 10/100 Ethernet cable (LAN)
- 1 10/100 Ethernet port (WAN)
- 1 attached USB / barrel 5vdc power cable
- 5 LEDs (see notes below)
- 1 reset button
- 1 UART (3 pads on board)

Installation:

The stock firmware does not support uploading new firmware directly,
only checking the manufacturer's site for updates.  This process may be
possible to spoof, but the update check uses some kind of homebrew
encryption that I didn't investigate.  Instead, you can install via a
backdoor:

1. Set up a TFTP server to serve the firmware binary
(lede-ramips-mt7620-var11n-300-squashfs-sysupgrade.bin)
2. Factory reset the device by holding the reset button for a few
seconds.
3. Open the web interface (default IP: 192.168.253.254)
4. Log in with the "super admin" credentials: username `vonets`,
password `vonets26642519`.
5. On the "Operative Status" page, click the text "System Uptime", then
quickly click the uptime value.
6. If successful, an alert dialog will appear reading "Ated start", and
the device will now accept telnet connections.  If the alert does not
appear, repeat step 5 until it works (the timing is a bit tricky).
7. Telnet to the device using credentials "admin / admin"
8. Retrieve the firmware binary from the tftp server: `tftp -l lede.bin
-r lede-ramips-mt7620-var11n-300-squashfs-sysupgrade.bin -g
<tftp-server-ip>`
9. Write the firmware to flash: `mtd_write write lede.bin /dev/mtd4`
10. Reboot

Tested:
- LAN / WAN ethernet
- WiFi
- LAN / WAN / status LED GPIOs (see notes below)
- Reset button
- Sysupgrade

Notes:

LEDs:

The board has 5 LEDs - two green LEDs for LAN / WAN activity, one blue
LED for WiFi, and a pair of "status" LEDs connected to the same GPIO
(the blue LED lights when the GPIO is low, and the green when it's
high).  I was unable to determine how to operate the WiFi LED, as it
does not appear to be controlled by a GPIO directly.

Recovery:

The default U-boot installation will only boot from flash due to a
missing environment block.  I generated a valid 4KB env block using
U-boot's `fw_setenv` tool and wrote it to flash at 0x30000 using an
external programmer.  After this, it was possible to enter the U-boot
commandline interface and download a new image via TFTP (`tftpboot
81b00000 <image-filename>`), but while I could boot this image
sucessfully (`bootm`), writing it to flash (`cp.linux`) just corrupted
the flash chip.  The sysupgrade file can be written to flash at 0x50000
using an external programmer.

- MT7628AN (580MHz)
- 64/128/256 MB of RAM (DDR2)
- 8/16 MB of flash (SPI NOR)
- 5x 10/100 Mbps Ethernet (MT7628 built-in switch)
- 1x 2T2R 2.4 GHz Wi-Fi (MT7628)
- 1x miniPCIe slot (with PCIe and USB 2.0 buses)
- 1x miniSIM slot
- 1x microSD slot
- 1x USB 2.0 port
- 7x single-color LEDs (GPIO-controlled)
- 1x bi-color LED (green GPIO-controlled, red -> LED_WLAN# in miniPCIe)
- 1x reset button
- 1x UART header (4-pins)
- 1x SDXC/GPIO header (10-pins, connected with microSD slot)
- 1x DC jack for main power (12 V)

The following has been tested and is working:

- Ethernet switch
- miniPCIe slot (tested with modem and Wi-Fi card)
- miniSIM slot
- sysupgrade
- reset button
- USB 2.0 port*

Due to a missing driver (MMC over GPIO) this is not supported:

- microSD card reader

* Warning:
USB buses in miniPCIe and regular A-type socket are connected together,
without any proper analog switch or USB HUB.

Installation:

This board might come with a different firmware versions (MediaTek SDK,
PandoraBox, Padavan, etc.). If your board comes with PandoraBox, you can
install LEDE using sysupgrade. Just SSH to the router and perform forced
sysupgrade (due to a board name mismatch). The default IP of this board
should be: 192.168.1.1 and username/password: root/admin. In case of a
different firmware, you can use web based recovery described below.

Use the following command to perform the sysupgrade (for the 128MB
RAM/16MB flash version):

sysupgrade -n -F lede-ramips-mt76x8-u7628-01-128M-16M-squashfs-sysupgrade.bin

Recovery:

This board contains a Chinese, closed-source bootloader called Breed
(Boot and Recovery Environment for Embedded Devices). Breed supports web
recovery and to enter it, you keep the reset button pressed for around
5 seconds during boot. Your machine will be assigned an IP through DHCP
and the router will use IP address 192.168.1.1. The recovery website is
in Chinese, but is easy to use. Click on the second item in the list to
access the recovery page, then the second item on the next page is where
you select the firmware. In order to start the recovery, you click the
button at the bottom.

SDXC/GPIO header (J3):

 1. SDXC_D3  / I2C_SCLK
 2. SDXC_D2  / I2C_SD
 3. SDXC_D1  / I2S_DI
 4. SDXC_D0  / I2S_WS
 5. SDXC_CMD / I2S_CLK
 6. SDXC_CLK / GPIO0
 7. SDXC_CD  / UART_RXD1
 8. UART_TXD1
 9. 3V3
10. GND

Other notes:

1. The board is available with different amounts of RAM and flash. We
have only added support for the 128/16 MB configuration, as that seems
to be the default. However, all the required infrastructure is in place
for making support for the other configurations easy.

- 1x UART header (4-pins)
- 1x GPIO header (30-pins)
- 1x FPC connector for LEDs (20-pin, 0.5 mm pitch)
- 1x DC jack for main power (12 V)

The following has been tested and is working:

- Ethernet switch
- miniPCIe slots (tested with Wi-Fi cards)
- mSATA slot (tested with modem and mSATA drive)
- miniSIM slot
- sysupgrade
- reset button
- microSD slot

Installation:

This board might come with a different firmware versions (MediaTek SDK,
PandoraBox, Padavan, etc.). If your board comes with PandoraBox, you can
install LEDE using sysupgrade. Just SSH to the router and perform forced
sysupgrade (due to a board name mismatch). The default IP of this board
should be: 192.168.1.1 and username/password: root/admin. In case of a
different firmware, you can use web based recovery described below.

Use the following command to perform the sysupgrade (for the 256MB
RAM/16MB flash version):

sysupgrade -n -F lede-ramips-mt7621-u7621-06-256M-16M-squashfs-sysupgrade.bin

Recovery:

This board contains a Chinese, closed-source bootloader called Breed
(Boot and Recovery Environment for Embedded Devices). Breed supports web
recovery and to enter it, you keep the reset button pressed for around
5 seconds during boot. Your machine will be assigned an IP through DHCP
and the router will use IP address 192.168.1.1. The recovery website is
in Chinese, but is easy to use. Click on the second item in the list to
access the recovery page, then the second item on the next page is where
you select the firmware. In order to start the recovery, you click the
button at the bottom.

LEDs list (top row, left to right):

- LED_WWAN# (connected with pin 42 in LTE/mSATA slot)
- Power (connected directly to 3V3)
- CTS2_N (GPIO10, configured as "status" LED)
- TXD2 (GPIO11, configured as "led4", without default trigger)
- RXD2 (GPIO12, configured as "led5", without default trigger)
- LED_WLAN# (connected with pin 44 in wifi0 slot)

LEDs list (bottom row, left to right):

- ESW_P0_LED_0
- ESW_P1_LED_0
- ESW_P2_LED_0
- ESW_P3_LED_0
- ESW_P4_LED_0
- LED_WLAN# (connected with pin 44 in wifi1 slot)

Other notes:

1. The board is available with different amounts of RAM and flash. We
have only added support for the 256/16 MB configuration, as that seems
to be the default. However, all the required infrastructure is in place
for making support for the other configurations easy.

2. The manufacturer offers five different wireless cards with MediaTek
chipsets, based on MT76x2, MT7603 and MT7615. Images of the board all
show that the miniPCIe slots are dedicated to specific Wi-Fi cards.
However, the slots are generic.

3. All boards we got access to had the same EEPROM content. The default
firmware reads the Ethernet MAC from offset 0xe000 in factory partition.
This offset only contains 0xffs, so a random MAC will be generated on
every boot of the router. There is a valid MAC stored at offset 0xe006
and this MAC is shown as the WAN MAC in the bootloader. However, it is
the same on all boards we have checked. Based on information provided
by the vendor, all boards sold in small quantities are considered more
as samples for development purposes.

Robert Marko d0ef27594a ramips: add support for TP-Link TL-WR840N v5
TP-Link TL-WR840N v5 is simple N300 router with 5-port FE switch and
non-detachable antennas, based on MediaTek MT7628NN (aka MT7628N) WiSoC.

Specification:

- MT7628N/N (580 MHz)
- 64 MB of RAM (DDR2)
- 4 MB of FLASH
- 2T2R 2.4 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 1x LED (GPIO-controlled), 1x button

* LED in TL-WR840N v5 is a dual-color, dual-leads type which isn't
  (fully) supported by gpio-leds driver. This type of LED requires both
  GPIOs state change at the same time to select color or turn it off.
  For now, we support/use only the green part of the LED.
  Orange LED is registered so you can later use it for your own purposes.

  Flash instruction:

  Unlike TL-WR840N v4 flashing through WEB UI works in v5.
  1. Download lede-ramips-mt76x8-tl-wr840n-v5-squashfs-sysupgrade.bin image.
  2. Go to 192.168.0.1
  3. Flash the sysupgrade image through Firmware upgrade section of WEB UI.
  4. Wait until green LED stops flashing and use the router.

Notes:
TFTP recovery is broken since TP-Link reused bootloader code for v4 and
that does not take into account only 4 MB of flash and bricks the device.
So do not use TFTP Recovery or you will have to rewrite SPI flash.
They fixed it in later GPL code,but it is unknown which version of
bootloader you have.

After manually compiling and flashing bootloader from GPL sources TFTP
recovery works properly.

Kevin Darbyshire-Bryant f2107fc328 ramips: improve Xiaomi Mi Router 3G support
This commit improves support for the Xiaomi Mi Router 3G originally
added in commit 6e283cdc0d

Improvements:

- Remove software watchdog as hardware watchdog now working as per
  commit 3fbf3ab44f for all mt7621
  devices.

- Reset button polarity corrected - length of press determines reboot
  (short press) vs. reset to defaults (long press) behaviour.

- Enable GPIO amber switch port LEDs on board rear - lit indicates 1Gbit
  link and blink on activity.  Green LEDs driven directly by switch
  indicating any link speed and tx activity.

- USB port power on/off GPIO exposed as 'usbpower'

- Add access to uboot environment settings for checking/setting uboot
  boot order preference from user space.

Changes:

- Front LED indicator is physically made of independent Yellow/Amber,
  Red & Blue LEDs combined via a plastic 'lightpipe' to a front panel
  indicator, hence the colour behaviour is similar to an RGB LED. RGB
  LEDs are not supported at this time because they produce colour results
  that do not then match colour labels, e.g. enabling 'mir3g:red' and
  'mir3g:blue' would result in a purple indicator and we have no such
  label for purple.
  The yellow, red & blue LEDs have been split out as individual yellow,
  red & blue status LEDs, with yellow being the default status LED as
  before and with red's WAN and blue's USB default associations removed.

- Swapped order of vlan interfaces (eth0.1 & eth0.2) to match stock vlan
  layout. eth0.1 is LAN, eth0.2 is WAN

- Add 'lwlll' vlan layout to mt7530 switch driver to prevent packet
  leakage between kernel switch init and uci swconfig

uboot behaviour & system 'recovery'

uboot expects to find bootable kernels at nand addresses 0x200000 &
0x600000 known by uboot as "system 1" and "system 2" respectively.
uboot chooses which system to hand control to based on 3 environment
variables: flag_last_success, flag_try_sys1_failed & flag_try_sys2_failed

last_success represents a preference for a particular system and is set
to 0 for system 1, set to 1 for system 2.  last_success is considered *if*
and only if both try_sys'n'_failed flags are 0 (ie. unset) If *either*
failed flags are set then uboot will attempt to hand control to the
non failed system. If both failed flags are set then uboot will check
the uImage CRC of system 1 and hand control to it if ok.  If the uImage
CRC of system is not ok, uboot will hand control to system 2
irrespective of system 2's uImage CRC.

NOTE: uboot only ever sets failed flags, it *never* clears them. uboot
sets a system's failed flag if that system's was selected for boot but
the uImage CRC is incorrect.

Fortunately with serial console access, uboot provides the ability to
boot an initramfs image transferred via tftp, similarly an image may
be flashed to nand however it will flash to *both* kernels so a backup
of stock kernel image is suggested. Note that the suggested install
procedure below set's system 1's failed flag (stock) thus uboot ignores
the last_success preference and boots LEDE located in system 2.

Considerable thought has gone into whether LEDE should replace both
kernels, only one (and which one) etc. LEDE kernels do not include a
minimal rootfs and thus unlike the stock kernel cannot include a
method of controlling uboot environment variables in the event of
rootfs mount failure. Similarly uboot fails to provide an external
mechanism for indicating boot system failure.

Installation - from stock.

Installation through telnet/ssh:
- copy lede-ramips-mt7621-mir3g-squashfs-kernel1.bin and
  lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin to usb disk or wget it
  from LEDE download site to /tmp
- switch to /extdisks/sda1/ (if copied to USB drive) or to /tmp if
  wgetted from LEDE download site
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin rootfs0
- run: nvram set flag_try_sys1_failed=1
- run: nvram commit
- run: reboot

Recovery - to stock.

Assuming you used the above installation instructions you will have a
stock kernel image in system 1. If it can be booted then it may be used
to perform a stock firmware recovery, thus erasing LEDE completely. From
a 'working' LEDE state (even failsafe)

Failsafe only:
- run: mount_root
- run: sh /etc/uci-defaults/30_uboot-envtools
Then do the steps for 'All'

All:
- run: fw_setenv flag_try_sys2_failed 1
- run: reboot

The board will reboot into system 1 (stock basic kernel) and wait with
system red light slowly blinking for a FAT formatted usb stick with a
recovery image to be inserted.  Press and hold the reset button for
around 1 second. Status LED will turn yellow during recovery and blue
when recovery complete.

Maxim Anisimov 161a3be5ad ramips: add support for TP-Link Archer C20 v1
TP-Link Archer C20 v1 is a router with 5-port FE switch and
non-detachable antennas. It's very similiar to TP-Link Archer C50.
Also it's based on MediaTek MT7620A+MT7610EN.

Specification:
- MediaTek MT7620A (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 8x LED (GPIO-controlled*), 2x button, power input switch
- 1 x USB 2.0 port

* WAN LED in this devices is a dual-color, dual-leads type which isn't
  (fully) supported by gpio-leds driver. This type of LED requires both
  GPIOs state change at the same time to select color or turn it off.
  For now, we support/use only the blue part of the LED.
* MT7610EN ac chip isn't not supported by LEDE. Therefore 5Ghz won't
  work.

Factory image notes:

These devices use version 3 of TP-Link header, fortunately without RSA
signature (at least in case of devices sold in Europe). The difference
lays in the requirement for a non-zero value in "Additional Hardware
Version" field. Ideally, it should match the value stored in vendor
firmware header on device.

We are able to prepare factory firwmare file which is accepted and
(almost) correctly flashed from the vendor GUI. As it turned out, it
accepts files without U-Boot image with second header at the beginning
but due to some kind of bug in upgrade routine, flashed image gets
corrupted before it's written to flash. So, to flash this device we must
to prepare image using original firmware from tp-link site with uboot.

Flash instruction:

Until (if at all) TP-Link fixes described problem, the only way to flash
LEDE image in these devices is to use tftp recovery mode in U-Boot.
There are two ways to flash the device to LEDE:

1) Using tftp mode with UART connection and original LEDE image

 - Place lede-ramips-mt7620-ArcherC20-squashfs-factory.bin in tftp
   server directory
 - Configure PC with static IP 192.168.0.66/24 and tftp server.
 - Connect PC with one of LAN ports, power up the router and press
   key "4" to access U-Boot CLI.
 - Use the following commands to update the device to LEDE:

    setenv serverip 192.168.0.66
    tftp 0x80060000 lede-ramips-mt7620-ArcherC20-squashfs-factory.bin
    erase tplink 0x20000 0x7a0000
    cp.b 0x80060000 0x20000 0x7a0000
    reset

 - After that the device will reboot and boot to LEDE

2) Using tftp mode without UART connection but require some
   manipulations with target image

 - Download and unpack TP-Link Archer C20 v1 firmware from original web
   site
 - Split uboot.bin from original firmware by this command (example):

    dd if=Archer_C20v1_0.9.1_4.0_up_boot(160427)_2016-04-27_13.53.59.bin of=uboot.bin bs=512 count=256 skip=1

 - Create ArcherC20V1_tp_recovery.bin using this command:

    cat uboot.bin lede-ramips-mt7620-ArcherC20-squashfs-factory.bin > ArcherC20V1_tp_recovery.bin

 - Place ArcherC20V1_tp_recovery.bin in tftp server directory.
 - Configure PC with static IP 192.168.0.66/24 and tftp server.
 - Connect PC with one of LAN ports, press the reset button, power up
   the router and keep button pressed for around 6-7 seconds, until
   device starts downloading the file.
 - Router will download file from server, write it to flash and reboot.

Kristian Evensen 79440ea756 ramips: Add support for ZBT WE1026-5G
The ZBT WE1026-5G
(http://www.zbtlink.com/products/router/WE1026-5G.html) is the follow-up
to the ZBT WE1026 and is based on MT7620. For the previous WE1026, the
ZBT WE826 image could be used. However, as the name implies, the -5G
comes equipped with a 5GHz wifi radio. As the WE826 only has a 2.4GHz
radio, the addition of 5GHz means that a separate image is needed for
the WE1026-5G. I suspect that this image will also work on the previous
WE1026, but I don't have a device to test with.

The WE1026-5G has following specifications:
* CPU: MT7620A
* 1x 10/100Mbps Ethernet.
* 16 MB Flash.
* 64 MB RAM.
* 1x USB 2.0 port.
* 1x mini-PCIe slots.
* 1x SIM slots.
* 1x 2.4Ghz WIFI.
* 1x 5GHz wifi (MT7612)
* 1x button.
* 3x controllable LEDs.

Works:
* Wifi.
* Switch.
* mini-PCIe slot. Only tested with a USB device (a modem).
* SIM slot.
* Sysupgrade.
* Button (reset).

Not working:
* The 5GHz WIFI LED is completely dead. I suspect the issue is the same
as on other devices with Mediatek 5Ghz wifi-cards/chips. The LED is
controlled by the driver, and mt76 (currently) does not support this.

Not tested:
* SD card reader.

Notes:
* The modem (labeled 3G/4G) and power LEDs are controlled by the
hardware.
* There is a 32MB version of this device available, but I do not have
access to it. I have therefor only added support for the 16MB version,
but added all the required infrastructure to make adding support for the
32MB version easy.

Installation:
The router comes pre-installed with OpenWRT, including a variant of
Luci. The initial firmware install can be done through this UI,
following normal procedure. I.e., access the UI and update the firmware
using the sysupgrade-image. Remember to select that you do not want to
keep existing settings.

Recovery:
If you brick the device, the WE1026-5G supports recovery using HTTP. Keep the
reset button pressed for ~5sec when booting to start the web server. Set the
address of the network interface on your machine to 192.168.1.2/24, and
point your browser to 192.168.1.1 to access the recovery UI. From the
recovery UI you can upload a firmware image.

Thibaut VARENE 991681cf49 ramips: Archer C50v1: support US and EU versions
For the Archer C50v1, the EU and US versions are differentiated by their
respective HW additional version (0x0 for US, 0x2 for EU).

The stock web interface checks this field before flashing, making it
impossible to flash the current (US) factory image on EU hardware.

However the bootloader does not check this field, making it possible to use
a single sysupgrade image for both hardware.

This patch adds the necessary build bits to generate both EU and US factory
images, and renames the target as "Archer C50v1" since there are as of now
3 different versions of Archer C50 (all with different CPUs).

Pavel Kubelun 6e283cdc0d ramips: add Xiaomi Mi Router 3G support
This commit adds support for Xiaomi Mi WiFi Router 3G.

Short specification:
 - MT7621AT + MT7603EN + 7612EN
 - 256MB DDR3 RAM
 - 128MB NAND flash
 - 1+2 x 1000M Ethernet
 - 1x USB 3.0 port
 - reset button
 - yellow, blue, red leds

Installation through telnet/ssh:
- copy lede-ramips-mt7621-mir3g-squashfs-kernel1.bin and
lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin to usb disk or wget it

wgetted from LEDE download site
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin rootfs0
- run: mtd erase kernel0
- run: reboot

Originally stock firmware has following partitions:
 - ...
 - kernel0 (primary kernel image)
 - kernel1 (secondary kernel image, used by u-boot in failsafe routine)
 - rootfs0 (primary rootfs)
 - rootfs1 (secondary rootfs in case primary fails)
 - overlay (used as ubi overlay)

This commit squashes rootfs0, rootfs1 and overlay partitions into 1, so
it can be used by LEDE fully for package installation, resulting in 117,5MiB.

This device lacks hw watchdog, so adding softdog instead (stock does the same).

Cleanup the dtsi files and remove one layer of dtsi. Set the size of
the firmware partition to a value matching the flash size from the
board (variant) name.

Remove the usb led trigger. There is neither a default config for the
usb led trigger nor a LED for usb activity indication.

Mathias Kresin 99f1097c0a ramips: fix Mercury MAC1200R v2.0 board name
With d2b6bf1416 ("ramips: fix image validation errors") the board
name was changed to fix an image validation error. But this change
wasn't applied to all other files using the board name, which broke
sysupgrade.

Revert this change and use the former board name in the metadata
instead.

Oliver Fleischmann a92c64e8ae ramips: add support for Loewe WMDR-143N
The WMDR-143N is a small module originally used as a Wifi client
in some Loewe smart TV sets. It is sold cheaply at german surplus
shops. The module contains a RT3662 SOC.

Specifications:

- 500 MHz CPU Clock
- 1x 10/100Mbps Ethernet (pin header)
- 32 MB of RAM
- 8 MB of FLASH
- 2T3R 2.4/5 GHz (SOC internal)
- 3 Antennas on PCB
- UART pads on PCB (J3: 1 = +3.3V, 2 = RX, 3 = TX, 4 = GND), TX
  and RX are 3,3V only! The square hole is pin 1
- Power supply pads on PCB (J6: 1 and 2 = +5V, 3 and 4 = GND)
  The square hole is pin 1

The original firmware has two identical kernel/rootfs images and
two "Factory" calibration data blocks in flash. The LEDE image
leaves only the first "Factory" block in place and uses both
"Kernel" blocks and the redundant "Factory" block together to gain
enough space for the jffs2 partition.

Flash instructions:

You need UART and Ethernet connections to flash the board. Use
the LEDE "sysupgrade.bin" image with tftp.

Apply power to the board and in the first 5 seconds, hit 2 to
select TFTP upload. The bootloader asks for board- and server IP
addresses and filename.

Alternate method: With the vendor firmware running, assign an IP
address to the ethernet port, tftp the firmware image to
/tmp and write to mtd4 ("KernelA").
