Adrian Schmutzler 30cc7f3510 ramips: increase SPI frequency for ASUS RT-AC51U/RT-AC54U
This increases the SPI frequency for both ASUS RT-AC51U and RT-AC54U.

Speed comparison tests have been performed on RT-AC54U:

- 10Mhz
root@OpenWrt:~# time cat /dev/mtd* > /dev/null
real    4m 37.78s
user    0m 0.02s
sys     2m 43.92s

- 50Mhz
root@OpenWrt:~# time cat /dev/mtd* > /dev/null
real    1m 28.34s
user    0m 0.03s
sys     0m 46.96s

- 50Mhz fast read
root@OpenWrt:~# time cat /dev/mtd* > /dev/null
real    1m 11.94s
user    0m 0.01s
sys     0m 46.94s

- 80Mhz
root@OpenWrt:~# time cat /dev/mtd* > /dev/null
real    1m 12.31s
user    0m 0.04s
sys     0m 46.96s

- 80Mhz fast read
root@OpenWrt:~# time cat /dev/mtd* > /dev/null
real    1m 12.15s
user    0m 0.02s
sys     0m 46.97s

Based on that, we took 50 MHz with fast-read, as higher frequencies
didn't yield further improvements.

For the RT-AC51U, only the final configuration was tested.

Davide Fioravanti 31b49f02ca ramips: add support for Linksys EA7500 v2
The Linksys EA7500 v2 is advertised as AC1900, but its internal
hardware is AC2600 capable.

Hardware
--------
SoC:   Mediatek MT7621AT (880 MHz, 2 cores 4 threads)
RAM:   256M (Nanya NT5CC128M16IP-DI)
FLASH: 128MB NAND (Macronix MX30LF1G18AC-TI)
ETH:   5x 10/100/1000 Mbps Ethernet (MT7530)
WIFI:
  - 2.4GHz: 1x MT7615N (4x4:4)
  - 5GHz:   1x MT7615N (4x4:4)
  - 4 antennas: 3 external detachable antennas and 1 internal
USB:
  - 1x USB 3.0
  - 1x USB 2.0
BTN:
  - 1x Reset button
  - 1x WPS button
LEDS:
  - 1x White led (Power)
  - 6x Green leds (link lan1-lan4, link wan, wps)
  - 5x Orange leds (act lan1-lan4, act wan) (working but unmodifiable)

Everything works correctly.

Installation
------------
The “factory” openwrt image can be flashed directly from OEM stock
firmware. After the flash the router will reboot automatically.

However, due to the dual boot system, the first installation could fail
(if you want to know why, read the footnotes).
If the flash succeed and you can reach OpenWrt through the web
interface or ssh, you are done.
Otherwise the router will try to boot 3 times and then will
automatically boot the OEM firmware (don’t turn off the router.
Simply wait and try to reach the router through the web interface
every now and then, it will take few minutes).

After this, you should be back in the OEM firmware.

Now you have to flash the OEM Firmware over itself using the OEM web
interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img
downloaded from the Linksys website).

When the router reboots flash the “factory” OpenWrt image and this
time it should work.

After the OpenWrt installation you have to use the sysupgrade image
for future updates.

Restore OEM Firmware
--------------------
After the OpenWrt flash, the OEM firmware is still stored in the
second partition thanks to the dual boot system.
You can switch from OpenWrt to OEM firmware and vice-versa failing
the boot 3 times in a row:
 1) power on the router
 2) wait 15 seconds
 3) power off the router
 4) repeat steps 1-2-3 twice more.
 5) power on the router and you should be in the “other” firmware

If you want to completely remove OpenWrt from your router, switch to
the OEM firmware and then flash OEM firmware from the web interface
as a normal update.
This procedure will overwrite the OpenWrt partition.

Footnotes
---------
The Linksys EA7500-v2 has a dual boot system to avoid bricks.
This system works using 2 pair of partitions:
 1) "kernel" and "rootfs"
 2) "alt_kernel" and "alt_rootfs".
After 3 failed boot attempts, the bootloader tries to boot the other
pair of partitions and so on.

This system is managed by the bootloader, which writes a bootcount in
the s_env partition, and if successfully booted, the system add a
"zero-bootcount" after the previous value.

A system update performed from OEM firmware, writes the firmware on the
other pair of partitions and sets the bootloader to boot the new pair
of partitions editing the “boot_part” variable in the bootloader vars.
Effectively it's a quick and safe system to switch the selected boot
partition.

Another way to switch the boot partition is:
 1) power on the router
 2) wait 15 seconds
 3) power off the router
 4) repeat steps 1-2-3 twice more.
 5) power on the router and you should be in the “other” firmware

In this OpenWrt port, this dual boot system is partially working
because the bootloader sets the right rootfs partition in the cmdline
but unfortunately OpenWrt for ramips platform overwrites the cmdline
so is not possible to detect the right rootfs partition.

Because all of this, I preferred to simply use the first pair of
partitions and set read-only the other pair.

However this solution is not optimal because is not possible to know
without opening the case which is the current booted partition.
Let’s take for example a router booting the OEM firmware from the first
pair of partitions. If we flash the OpenWrt image, it will be written
on the second pair. In this situation the router will bootloop 3 times
and then will automatically come back to the first pair of partitions
containg the OEM firmware.
In this situation, to flash OpenWrt correctly is necessary to switch
the booting partition, flashing again the OEM firmware over itself.
At this point the OEM firmware is on both pair of partitions but the
current booted pair is the second one.
Now, flashing the OpenWrt factory image will write the firmware on
the first pair and then will boot correctly.

If this limitation in the ramips platform about the cmdline will be
fixed, the dual boot system can also be implemented in OpenWrt with
almost no effort.

Zhijun You 46674723e1 ramips: add support for ASUS RT-AC54U
Specification:

- CPU: MTK MT7620A
- RAM: 64MB
- ROM: 16MB SPI Flash Macronix MX25L12835E
- WiFi1: MediaTek MT7620A
- WiFi2: MediaTek MT7612E

- Ethernet: 5 ports, 4 LAN + 1 WAN
- Other: 1x UART 1x USB2.0

Installation:

   Update using ASUS Firmware Restoration Tool:

1. Download the ASUS Firmware Restoration Tool but don't open it yet
2. Unplug your computer from the router
3. Put the router into Rescue Mode by: turning the power off, using a pin
   to press and hold the reset button, then turning the router back on while
   keeping the reset button pressed for ~5 secs until the power LED starts
   flashing slowly (which indicates the router has entered Rescue Mode)
4. Important (if you don't do this next step the Asus Firmware
   Restoration Tool will wrongly assume that the router is not in Rescue Mode
   and will refuse to flash it): go to the Windows Control Panel and
   temporarily disable ALL other network adapters except the one you will use
   to connect your computer to the router
5. For the single adapter you left enabled, temporarily give it the
   static IP 192.168.1.10 and the subnet mask 255.255.255.0
6. Connect a LAN cable between your computer (make sure to use the
   Ethernet port of the adapter you've just set up) and port 1 of the router
   (not the router's WAN port)
7. Rename sysupgrade.bin to factory.trx
8. Open the Asus Firmware Restoration Tool, locate factory.trx and click
   upload (if Windows shows a compatibility prompt, confirm that the tool worked fine)
9. Flashing and reboot is finished when the power LED stops blinking and
   stays on

This phy act as a RGMII-to-SerDes converter.

Also a I2C clock gate needs to be enabled in order to access the SFP module via I2C bus.
SFP cage also has module detect pin which is connected to I2C gpio expander.

With this patch the kernel/PHYLINK now can detect, readout and use the SFP module/port.

NOTE: SFP cage / AT8033 PHY only support 1000base-X encoding!
This means that some SGMII modules can work and only at forced 1GBit/full-duplex!

Adrian Schmutzler f761f4052c ramips: mt7621: harmonize naming scheme for Mikrotik
So far, image/device/board names for Mikrotik devices in mt7621 have
been used quite inconsistently.

This patch harmonizes the naming scheme by applying the same style
as used lately in ath79, i.e. using "RouterBOARD" as separate word
in the model name (instead of RB prefix for the number) and deriving
the board/device name from that (= make lower case and replace spaces
by hyphens).

This style has already been used for most the model/DEVICE_MODEL
variables in mt7621, so this is essentially just adjusting the remaining
variables to that.

To avoid conflict with the master port (gmac0), rename it to "dsa".

The official firmware assigns MAC address in this way:
eth0 = label mac
eth1 = label mac + 1
...
eth4 = label mac + 4

Since we have switched to DSA, it's possible to use different MAC for each port.

RAM:   128M DDR3 (Winbond W631GG6KB)
LED:   Dome (Blue / White)
BTN:   Reset

Installation
------------

These instructions were written for firmware version v3.9.27.
Downgrade if necessary.

1. Copy the OpenWrt sysupgrade image to the devices /tmp folder
   via scp. On factory defaults, user and password is "ubnt" at
   192.168.1.20/24.

2. Write the bootselect flag. Otherwise, the device might boot from the
   wrong partition. Verify the mtd partition used in the command below
   is the one labled "bs" in /proc/mtd (as this might change in the
   future).

   > dd if=/dev/zero bs=1 count=1 of=/dev/mtd4

3. Write the OpenWrt sysupgrade to the mtd partitions labled
   "kernel0" and "kernel1".

   > dd if=/tmp/openwrt-sysupgrade.bin of=/dev/mtdblock6
   > dd if=/tmp/openwrt-sysupgrade.bin of=/dev/mtdblock7

2.4 *:4c uboot 0x1fc00
5   *:4e uboot 0x1fc00 +2

Installation
------------

Web interface:
It is possible to upgrade to OpenWrt via the web interface. However, the
OEM firmware upgrade file is required and a tool to fix the MD5 sum of
the header. This procedure overwrites U-Boot and there is not failsafe /
recovery mode present! To prepare an image, you need to take the header
and U-Boot (i.e. 0x200 + 0x20000 bytes) from an OEM firmware file and
attach the factory image to it. Then fix the header MD5Sum1.

Serial/TFTP:
You can use initramfs for booting via RAM or flash the image directly.

Additional Notes:
If the web interface upgrade fails, you have to open your device and
attach serial console. Since the web upgrade overwrites the boot loader,
you might also brick your device.

In order to flash back to stock, the first header and U-Boot needs to be
stripped from the original firmware.

Andreas Böhler 6d6f36ae78 ramips: add support for TP-Link RE200 v2
TP-Link RE200 v2 is a wireless range extender with Ethernet and 2.4G and 5G
WiFi with internal antennas. It's based on MediaTek MT7628AN+MT7610EN.

Specifications
--------------

- MediaTek MT7628AN (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 1x 10/100 Mbps Ethernet
- UART header on PCB (57600 8n1)
- 8x LED (GPIO-controlled), 2x button

There are 2.4G and 5G LEDs in red and green which are controlled
separately.

MAC addresses
-------------

The MAC address assignment matches stock firmware, i.e.:
LAN : *:0D
2.4G: *:0E
5G  : *:0F

Installation
------------

Web Interface
-------------

It is possible to upgrade to OpenWrt via the web interface. Simply flash
the -factory.bin from OEM. In contrast to a stock firmware, this will not
overwrite U-Boot.

Serial console
--------------

Opening the case is quite hard, since it is welded together. Rename the
OpenWrt factory image to "test.bin", then plug in the device and quickly
press "2" to enter flash mode (no line feed). Follow the prompts until
OpenWrt is installed.

Unfortunately, this devices does not offer a recovery mode or a tftp
installation method. If the web interface upgrade fails, you have to open
your device and attach serial console.

Additonal notes
---------------

It is possible to flash back to stock by using tplink-safeloader to create
a sysupgrade image based on a stock update. After the first boot, it is
necessary upgrade to another stock image, otherwise subsequent boots
fail with LZMA ERROR 1 and you have to attach serial to recover the device.

Maxim Anisimov 86e7353bff ramips: add support for TP-Link Archer C20 v5
TP-Link Archer C20 v5 is a router with 5-port FE switch and
non-detachable antennas. It's based on MediaTek MT7628N+MT7610EN.

Specification:
- MediaTek MT7628N/N (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 5x 10/100 Mbps Ethernet
- 3x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 7x LED (GPIO-controlled*), 2x button, power input switch

* 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 green part of the LED.

Create Factory image
--------------------
As all installation methods require a U-Boot to be integrated into the
Image (and we do not ship one with the image) we are not able to create
an image in the OpenWRT build-process.

Download a TP-Link image from their Website and a OpenWRT sysupgrade
image for the device and build yourself a factory image like following:

TP-Link image:             tpl.bin
OpenWRT sysupgrade image:  owrt.bin

 > dd if=tpl.bin of=boot.bin bs=131584 count=1
 > cat owrt.bin >> boot.bin

Installing via Web-UI
---------------------
Upload the boot.bin via TP-Links firmware upgrade tool in the
web-interface.

Installing via Recovery
-----------------------
Activate Web-Recovery by beginning the upgrade Process with a
Firmware-Image from TP-Link. After starting the Firmware Upgrade,
wait ~3 seconds (When update status is switching to 0%), then
disconnect the power supply from the device. Upgrade flag (which
activates Web-Recovery) is written before the OS-image is touched and
removed after write is succesfull, so this procedure should be safe.

Plug the power back in. It will come up in Recovery-Mode on 192.168.0.1.
When active, all LEDs but the WPS LED are off.
Remeber to assign yourself a static IP-address as DHCP is not active in
this mode.

The boot.bin can now be uploaded and flashed using the web-recovery.

Installing via TFTP
-------------------
Prepare an image like following (Filenames from factory image steps
apply here)

 > dd if=/dev/zero of=tp_recovery.bin bs=196608 count=1
 > dd if=tpl.bin of=tmp.bin bs=131584 count=1
 > dd if=tmp.bin of=boot.bin bs=512 skip=1
 > cat boot.bin >> tp_recovery.bin
 > cat owrt.bin >> tp_recovery.bin

Place tp_recovery.bin in root directory of TFTP server and listen on
192.168.0.66/24.

Connect router LAN ports with your computer and power up the router
while pressing the reset button. The router will download the image via
tftp and after ~1 Minute reboot into OpenWRT.

U-Boot CLI
----------
U-Boot CLI can be activated by holding down '4' on bootup.

Dual U-Boot
-----------
This is TP-Link MediaTek device with a split-uboot feature design like
a TP-Link Archer C50 v4. The first (factory-uboot) provides recovery via
TFTP and HTTP, jumping straight into the second (firmware-uboot) if no
recovery needs to be performed. The firmware-uboot unpacks and executed
the kernel.

Web-Recovery
------------
TP-Link integrated a new Web-Recovery like the one on the Archer C7v4 /
TL-WR1043v5 / Archer C50v4. Stock-firmware sets a flag in the "romfile"
partition before beginning to write and removes it afterwards. If the
router boots with this flag set, bootloader will automatically start
Web-recovery and listens on 192.168.0.1. This way, the vendor-firmware
or an OpenWRT factory image can be written.

By doing the same while performing sysupgrade, we can take advantage of
the Web-recovery in OpenWRT.

It is important to note that Web-Recovery is only based on this flag. It
can't detect e.g. a crashing kernel or other means. Once activated it
won't boot the OS before a recovery action (either via TFTP or HTTP) is
performed. This recovery-mode is indicated by an illuminated WPS-LED on
boot.

Andreas Böhler a3010a7f8d ramips: add support for TP-Link RE200 v1
TP-Link RE200 v1 is a wireless range extender with Ethernet and 2.4G and 5G
WiFi with internal antennas. It's based on MediaTek MT7620A+MT7610EN.

Specifications
--------------

- MediaTek MT7620A (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 1x 10/100 Mbps Ethernet
- UART header on PCB (57600 8n1)
- 8x LED (GPIO-controlled; only 6 supported), 2x button

There are 2.4G and 5G LEDs in red and green which are controlled
separately. The 5G LED is currently not supported, since the GPIOs couldn't
be determined.

Installation
------------

Web Interface
-------------

It is possible to upgrade to OpenWrt via the web interface. However, the
OEM firmware upgrade file is required and a tool to fix the MD5 sum of
the header. This procedure overwrites U-Boot and there is not failsafe /
recovery mode present! To prepare an image, you need to take the header
and U-Boot (i.e. 0x200 + 0x20000 bytes) from an OEM firmware file and
attach the factory image to it. Then fix the header MD5Sum1.

Serial console
--------------

Opening the case is quite hard, since it is welded together. Rename the
OpenWrt factory image to "test.bin", then plug in the device and quickly
press "2" to enter flash mode (no line feed). Follow the prompts until
OpenWrt is installed.

Unfortunately, this devices does not offer a recovery mode or a tftp
installation method. If the web interface upgrade fails, you have to open
your device and attach serial console. Since the web upgrade overwrites
the boot loader, you might also brick your device.

Additional notes
----------------

MAC address assignment is based on stock-firmware. For me, the device
assigns the MAC on the label to Ethernet and the 2.4G WiFi, while the 5G
WiFi has a separate MAC with +2.

*:88    Ethernet/2.4G    label, uboot 0x1fc00, userconfig 0x0158
*:89    unused           userconfig 0x0160
*:8A    5G               not present in flash

This seems to be the first ramips device with a TP-Link v1 header. The
original firmware has the string "EU" embedded, there might be some region-
checking going on during the firmware upgrade process. The original
firmware also contains U-Boot and thus overwrites the boot loader during
upgrade.
In order to flash back to stock, the first header and U-Boot need to be
stripped from the original firmware.

Adrian Schmutzler 09d38a3bc3 ramips: remove bogus ralink,mtd-eeprom with offset 0x4
Several devices in mt76x8 subtarget use the following line to set
up wmac in their DTS(I) files:

ralink,mtd-eeprom = <&factory 0x4>

This is strange for several reasons:
- They should use mediatek,mtd-eeprom on this SOC
- The caldata is supposed to start at 0x0
- The parent DTSI mt7628an.dtsi specifies mediatek,mtd-eeprom anyway,
  starting from 0x0
- The offset coincides with the default location of the MAC address
  in caldata

Based on the comment in b28e94d4bf ("ramips: MiWiFi Nano fixes"),
it looks like the author for this device wanted to actually use
mtd-mac-address instead of ralink,mtd-eeprom. A check on the same
device revealed that actually the MAC address start at offset 4 there,
so the correct caldata offset is 0x0.

Based on these findings, and the fact that the expected location on
this SOC is 0x0, we remove the "ralink,mtd-eeprom = <&factory 0x4>"
statement from all devices in ramips (being only mt7628an anyway).

Thanks to Sungbo Eo for finding and researching this.

Sungbo Eo 38bdfcdb87 ramips: add support for ipTIME A104ns
ipTIME A104ns is a 2.4/5GHz band AC750 router, based on MediaTek MT7620A.

Specifications:
- SoC: MT7620A
- RAM: DDR2 64MB
- Flash: SPI NOR 8MB
- WiFi:
  - 2.4GHz: SoC internal
  - 5GHz: MT7610EN
- Ethernet: 5x 10/100Mbps
  - Switch: SoC internal
- USB: 1x 2.0
- UART:
  - J2: 3.3V, TX, RX, GND (3.3V is the square pad) / 57600 8N1

Installation via web interface:
1.  Flash **initramfs** image through the stock web interface.
2.  Boot into OpenWrt and perform sysupgrade with sysupgrade image.

Revert to stock firmware:
1.  Perform sysupgrade with stock image.

In contrast to to-be-supported A1004ns, the A104ns has no usable
value in 0x1fc40 (uboot), so wan_mac needs to be calculated.
Also note that GPIOs for the LEDs really are inverted compared to
the A1004ns.

[moved state_default to device DTS, reordered properties in wmac,
added comment about wan_mac and LED GPIOs]

Birger Koblitz 8007853f79 ramips: remove unnecessary nodes in DTS for Edimax RG21S
This sdhci and i2c nodes were copy-pasted, but are not needed as
the device does not provide that functionality. Remove them.
