Adrian Schmutzler 121c021989 ramips: invert wpad selection for mt7621
For ramips/mt7621, the wpad-basic package is not selected by default,
but added for every device individually as needed.

While this might be technically correct if the SoC does not come with
a Wifi module, only 18 of 97 devices for that platform are set up
_without_ wpad-basic currently.

Therefore, it seems more convenient to add wpad-basic by default for
the subtarget and then just remove it for the 18 mentioned devices,
instead of having to add it for about 60 times instead.

This would also match the behavior of the 5 other subtargets, where
wpad-basic/wpad-mini is added by default as well, and thus be more
obvious to developers without detailed SoC knowledge.

Alexey Dobrovolsky 4c73c34ec4 ramips: switch rt305x subtarget to kernel 5.4
RT3x5x seems to work fine with kernel 5.4. Set the default kernel
version to 5.4 to bring this to a broader audience.

Since 4 of 6 targets are on kernel 5.4 now, invert the kernel
version setup logic in Makefile/target.mk files.

Tested on ZyXEL Keenetic.

Adrian Schmutzler 356866c481 target: replace remaining occurrences of ifconfig with ip
ifconfig is effectively deprecated for quite some time now. Let's
replace the remaining occurrences for our target setup by the
corresponding ip commands now.

Note that this does not touch ar71xx, as it will be dropped anyway,
and changing it would only make backports harder.

Josh Bendavid 11bff24b3e ramips: add support for D-Link DIR-1960 A1
This patch adds support for D-Link DIR-1960 A1. Given the similarity with
the DIR-1760/2660 A1, this patch also introduces a common DTSI which can
be shared with these devices, with support to be added in future commits.

Specifications:
* Board: AP-MTKH7-0002
* SoC: MediaTek MT7621AT
* RAM: 256 MB (DDR3)
* Flash: 128 MB (NAND)
* WiFi: MediaTek MT7615N (x2)
* Switch: 1 WAN, 4 LAN (Gigabit)
* Ports: 1 USB 3.0
* Buttons: Reset, WPS
* LEDs: Power (white/orange), Internet (white/orange), WiFi 2.4G (white),
        WiFi 5G (white), USB 3.0 (white)

Notes:
* WiFi 2.4G and WiFi 5G LEDs are wired directly to the wireless chips

Installation:
* D-Link Recovery GUI: power down the router, press and hold the reset
  button, then re-plug it. Keep the reset button pressed until the power
  LED starts flashing orange, manually assign a static IP address under
  the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1

* Some modern browsers may have problems flashing via the Recovery GUI,
  if that occurs consider uploading the firmware through cURL:

    curl -v -i -F "firmware=@file.bin" 192.168.0.1

MAC addresses:

lan   factory 0xe000     *:EB (label)
wan   factory 0xe006     *:EE

John Thomson 8484d6da1e ramips: remove non-existant poe_passthrough for RouterBOARD 750Gr3
This 750gr3 GPIO17 switch was added based on vendor source,
but only the 760iGS (which shares the rbsysfs board identifier)
device has the physical wiring. The 750Gr3 actually does not
support PoE out.

Apart from that, note that the gpio base (480) would have required
this GPIO to be referenced as 497 if it was kept.

Davide Fioravanti 92780d80ab ramips: add support for Winstars WS-WN583A6
The Winstars WS-WN583A6 is a wireless repeater with 2 gigabit ethernet
ports. Even if mine is branded as "Gemeita AC2100", the sticker on the
back says WS-WN583A6. So I will refer to it as Winstars WS-WN583A6.
Probably the real product name is the Wavlink WL-WN583A6 because of
the many references to Wavlink in the OEM firmware and bootlog.

Hardware
--------
SoC:   Mediatek MT7621AT (880 MHz, 2 cores 4 threads)
RAM:   128MB
FLASH: 8MB NOR (GigaDevice GD25Q64B)
ETH:   2x 10/100/1000 Mbps Ethernet (MT7530)
WIFI:
  - 2.4GHz: 1x MT7603E (2x2:2)
  - 5GHz:   1x MT7615E (4x4:4)
  - 6 internal antennas
BTN:
  - 1x Reset button
  - 1x WPS button
  - 1x ON/OFF switch (working but unmodifiable)
  - 1x Auto/Schedule switch (working but unmodifiable. Read Note #3)
LEDS:
  - 1x White led
  - 1x Red led
  - 1x Amber led
  - 1x Blue led
  - 2x Blue leds (lan and wan port status: working but unmodifiable)
UART:
  - 57600-8-N-1

Everything works correctly.

Currently there is no firmware update available. Because of this, in
order to restore the OEM firmware, you must firstly dump the OEM
firmware from your router before you flash the OpenWrt image.

Backup the OEM Firmware
-----------------------
The following steps are to be intended for users having little to none
experience in linux. Obviously there are many ways to backup the OEM
firmware, but probably this is the easiest way for this router.
Procedure tested on M83A6.V5030.191210 firmware version.

1) Go to http://192.168.10.1/webcmd.shtml

2) Type the following line in the "Command" input box:
	mkdir /etc_ro/lighttpd/www/dev; for i in /dev/mtd*ro; do dd if=${i} of=/etc_ro/lighttpd/www${i}; done

3) Click "Apply"

4) After few seconds, in the textarea should appear this output:
		16384+0 records in
	16384+0 records out
	8388608 bytes (8.0MB) copied, 4.038820 seconds, 2.0MB/s

	8060928 bytes (7.7MB) copied, 3.885280 seconds, 2.0MB/s
	dd: can't open '/dev/mtd5ro': No such device
	dd: can't open '/dev/mtd6ro': No such device
	dd: can't open '/dev/mtd7ro': No such device

   Excluding the "X.XXXXXX seconds" part, you should get the same
   exact output. If your output doesn't match mine, stop reading
   and ask for help in the forum.

5) Open the following links to download the partitions of the OEM FW:
	http://192.168.10.1/dev/mtd0ro
	http://192.168.10.1/dev/mtd1ro
	http://192.168.10.1/dev/mtd2ro
	http://192.168.10.1/dev/mtd3ro
	http://192.168.10.1/dev/mtd4ro

   If one (or more) of these files weight 0 byte, stop reading and ask
   for help in the forum.

6) Store these downloaded files in a safe place.

7) Reboot your router to remove any temporary file from your router.

Installation
------------
Flash the initramfs image in the OEM firmware interface.
When openwrt boots, flash the sysupgrade image otherwise you won't be
able to keep configuration between reboots.

Restore OEM Firmware
--------------------
Flash the "mtd4ro" file you previously backed-up directly from LUCI.
Warning: Remember to not keep settings!
Warning2: Remember to force the flash.

Notes
-----
1) The "System Command" page allows to run every command as root.
   For example you can use "dd" and "nc" to backup the OEM firmware.
   PC (SERVER):
	nc -l 5555 > ./mtdXro
   ROUTER (CLIENT):
	dd if=/dev/mtdXro | nc PC_IP_ADDRESS 5555

2) The OEM web interface accepts only images containing the string
   "WN583A6" in the filename.
   Currently the OEM interface accepts only the initramfs image
   probably because it checks if the ih_size in the image header is
   equal to the whole image size (instead of the kernel size)
   Read more here:
   https://forum.openwrt.org/t/support-for-strong-1200/22768/19

3) The white led (namely "Smart Night Light") can be controller by the
   user only if the side switch is set to "Schedule" otherwise it will
   be activated by the light condition (there is a photodiode on the
   top side of the router)

4) Router mac addresses:

   LAN		XX:XX:XX:XX:XX:8F
   WAN		XX:XX:XX:XX:XX:90
   WIFI 2G	XX:XX:XX:XX:XX:91
   WIFI 5G	XX:XX:XX:XX:XX:92

Everything works! Been running it for a couple weeks now and haven't had
any problems. Please let me know if you run into any.

Installation:

Flash factory image through GUI.

This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.

Reverting to factory firmware:

Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

Bjørn Mork c1794d653c ramips: add support for ZyXEL WAP6805 (Altibox WiFi+)
Hardware
--------
SoC:   MediaTek MT7621ST
WiFi:  MediaTek MT7603
       Quantenna QT3840BC
Flash: 128M NAND
RAM:   64M
LED:   Dual colour red and green
BTN:   Reset
       WPS
Eth:   4 x 10/100/1000 connected to MT7621 internal switch
       MT7621 RGMII port connected to Quantenna module
GPIO:  Power/reset of Quantenna module

Quantenna module
----------------

The Quantenna QT3840BC (or QV840) is a separate SoC running
another Linux installation.  It is mounted on a wide mini-PCIe
form factor module, but is connected to the RGMII port of
the MT7621.  It loads both a second uboot stage and an os
image from the MT7621 using tftp.  The module is configured
using Quantenna specific RPC calls over IP, using 802.1q
over the RGMII link to support multiple SSIDs.

There is no support for using this module as a WiFi device
in OpenWrt. A package with basic firmware and management
tools is being prepared.

Serial ports
------------

Two serial ports with headers:

RRJ1 - 115200 8N1 - Connected to the Quantenna console
J1   -  57600 8N1 - Connected to the MT7621 console

Both share pinout with many other Zyxel/Mitrastar devices:

1 - NC (VDD)
2 - TX
3 - RX
4 - NC (no pin)
5 - GND

Dual system partitions
----------------------

The vendor firmware and boot loader use a dual partition
scheme storing a counter in the header of each partition. The
partition with the highest number will be selected for boot.

OpenWrt does not support this scheme and will always use the
first OS partition.  It will reset both counters to zero the
first time sysupgrade is run, making sure the first partition
is selected by the boot loader.

Installation from vendor firmware
---------------------------------

1. Run a DHCP server. The WAP6805 is configured as a client device
   and does not have a default static IP address. Make a note of
   which address it is assigned

2. tftp the OpenWrt initramfs-kernel.bin image to this address.
   Wait for the WAP6805 to reboot.

3. ssh to the OpenWrt initramfs system on 192.168.1.1. Make a
   backup of all mtd partitions now.  The last used OEM image is
   still present in either "Kernel" or "Kernel2" at this point,
   and can be restored later if you save a copy.

4. sysupgrade to the OpenWrt sysupgrade.bin image.

Installation from U-Boot
------------------------

This requires serial console access

1. Copy the OpenWrt initramfs-kernel.bin image as "ras.bin" to
   your tftp server directory.  Configure the server address as
   192.168.0.33/24

2. Hit ESC when the message "Hit ESC key to stop autoboot"
   appears

3. Type "ATGU" + Enter, and then "2" immediately after pressing enter.

4. Answer Y to the question "Erase Linux in Flash then burn new
   one. Are you sure?", and answer the address/filename questions.
   Defaults:
        Input device IP (192.168.0.2)
        Input server IP (192.168.0.33)
        Input Linux Kernel filename ("ras.bin")

5. Wait until after you see the message "Done!" and power cycle
   the device.  It will hang after flashing.

6. Continue with step 3 and 4 from the vendor firmware procedure.

Notes on the WAP6805 U-Boot
---------------------------
The bootloader has been modified with both ZyXELs zyloader and the
device specific dual partition scheme.  These changes appear to have
broken a few things.  The zyloader shell claims to support a number
of ZyXEL AT commands, but not all of them work.  The image selection
scheme is unreliable and inconsistent.  A limited U-Boot menu is
available - and used by the above U-Boot install procedure.  But
direct booting into an uploaded image does not work, neither with
ram nor with flash.  Flashing works, but requires a hard reset after
it is finished.

Reverting to OEM firmware
-------------------------

The OEM firmware can be restored by using mtd write from OpenWrt,
flashing it to the "Kernel" partition. E.g.

  ssh root@192.168.1.1 "mtd -r -e Kernel write - Kernel" < oem.bin

OEM firmwares for the WAP6805 are not avaible for public download,
so a backup of the original installation is required.  See above.

Alternatively, firmware for the WAP6806 (Armor X1) may be used. This
is exactly the same hardware.  But the branding features do obviously
differ.

LED controller
--------------

Hardware implementation is unknown.  The dual-color LED is controlled
by 3 GPIOs:

  4: red
  7: blinking green
 13: green

Enabling both red and green makes the LED appear yellow.

The boot loader enables hardware blinking, causing the green LED to blink
slowly on power-on, until the OpenWrt boot mode starts a faster software
blink.

Restore OEM Firmware
--------------------
Flash the OEM "bin" firmware directly from LUCI.
The firmware is downloadable from the OEM web page.
Warning: Remember to not keep settings!
Warning2: Remember to force the flash.

Restoring procedure tested with RE23_1.08.bin

MAC addresses
-------------
factory 0x4     *:24
factory 0x8004  *:25
Cimage  0x07    *:24
Cimage  0x0D    *:24
Cimage  0x13    *:24
Cimage  0x19    *:25

No other addresses were found in factory partition.

Since the label contains both the 2.4GHz and 5GHz mac address I decided
to set the 5GHz one as label-mac-device. Moreover it also corresponds
to the lan mac address.

Notes
-----
The wifi led in the OEM firmware changes colour depending on the signal
strength. This can be done in OpenWrt but just for one interface.
So for now will not be any default action for this led.

If you want to open the case, pay attention to the antenna placed on
the bottom part of the front cover.
The wire is a bit short and it breaks easily. (I broke it)

Christoph Krapp ba0f4f0cfd ramips: add support for TP-Link RE500 v1
This device uses the same hardware as RE650 v1 which got supported in
8c51dde.

Hardware specification:

- SoC 880 MHz - MediaTek MT7621AT
- 128 MB of DDR3 RAM
- 16 MB - Winbond 25Q128FVSG
- 4T4R 2.4 GHz - MediaTek MT7615E
- 4T4R 5 GHz - MediaTek MT7615E
- 1x 1 Gbps Ethernet - MT7621AT integrated
- 7x LEDs (Power, 2G, 5G, WPS(x2), Lan(x2))
- 4x buttons (Reset, Power, WPS, LED)
- UART header (J1) - 2:GND, 3:RX, 4:TX
  Serial console @ 57600,8n1

Flash instructions:

Upload
openwrt-ramips-mt7621-tplink_re500-v1-squashfs-factory.bin
from the RE500 web interface.

TFTP recovery to stock firmware:

Unfortunately, I can't find an easy way to recover the RE
without opening the device and using modified binaries. The
TFTP upload will only work if selected from u-boot, which
means you have to open the device and attach to the serial
console. The TFTP update procedure does *not* accept the
published vendor firmware binaries. However, it allows to
flash kernel + rootfs binaries, and this works if you have
a backup of the original contents of the flash. It's probably
possible to create special image out of the vendor binaries
and use that as recovery image.

Perry Melange 22468cc40c ramips: erx and erx-sfp: fix missing WAN interface
This partially reverts commit 5acd1ed0be ("ramips: mt7621: fix
Ubiquiti ER-X ports names and MAC addresses"), this change was discussed
in https://github.com/openwrt/openwrt/pull/2901#discussion_r407238452

With commit 5acd1ed0be ("ramips: mt7621: fix Ubiquiti ER-X ports names
and MAC addresses"), all the ports were put into the LAN bridge, with
the argument that the OEM firmware does not have a WAN port enabled.  In
the default OEM setup, all of the ports except eth0 are dead and eth0 is
set to a static IP address without providing DHCP services when
connected.  It is only after the wizard has been run that eth0 becomes
the WAN port and all the rest of the ports belong to LAN with DHCP
enabled.

Having all of the ports set to the LAN bridge does not mirror the default
OEM setup.  To accomplish that, then only eth0 would be in the LAN bridge.
But this is not the expected behaviour of OpenWrt.

Therefore this proposal to set eth0 to WAN and eth1-N to LAN provides
the expected behaviour expected from OpenWrt, maintains the current
documentation as up-to-date, and does not require the user to manually
detach eth0 from the LAN bridge, create the WAN(6) interface(s), and set
eth0 to the WAN(6) interface(s).

Richard Huynh f3792690c4 ramips: Add support for Xiaomi Redmi Router AC2100 (RM2100)
Specification:
- CPU: MediaTek MT7621A
- RAM: 128 MB DDR3
- FLASH: 128 MB ESMT NAND
- WIFI: 2x2 802.11bgn (MT7603)
- WIFI: 4x4 802.11ac (MT7615)
- ETH: 3xLAN+1xWAN 1000base-T
- LED: Power, WAN, in Amber and White
- UART: On board near ethernet, opposite side from power
- Modified u-boot

Installation:

1. Run linked exploit to get shell, startup telnet and wget the files over
2. mtd write openwrt-ramips-mt7621-xiaomi_rm2100-squashfs-kernel1.bin kernel1
3. nvram set uart_en=1
4. nvram set bootdelay=5
5. nvram set flag_try_sys1_failed=1
6. nvram commit
7. mtd -r write openwrt-ramips-mt7621-xiaomi_rm2100-squashfs-rootfs0.bin rootfs0

Restore to stock:

1. Setup PXE and TFTP server serving stock firmware image
(See dhcp-boot option of dnsmasq)
2. Hold reset button down before powering on and wait for flashing amber led
3. Release reset button
4. Wait until status led changes from flashing amber to white

Notes:
This device has dual kernel and rootfs slots like other Xiaomi devices currently
supported (mir3g, etc.) thus, we use the second slot and overwrite the first
rootfs onwards in order to get more space.

Exploit and detailed instructions:

https://openwrt.org/toh/xiaomi/xiaomi_redmi_router_ac2100

An implementation of CVE-2020-8597 against stock firmware version 1.0.14

This requires a computer with ethernet plugged into the wan port and an active
PPPoE session, and if successful will open a reverse shell to 192.168.31.177
on port 31337.

As this shell is somewhat unreliable and likely to be killed in a random amount
of time, it is recommended to wget a static compiled busybox binary onto the
device and start telnetd with it.

The stock telnetd and dropbear unfortunately appear inoperable.
(Disabled on release versions of stock firmware likely)

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.

I-O DATA WN-AX2033GR is roughly the same as I-O DATA
WN-AX1167GR2. The difference is Wi-Fi feature.

Specification
=============
- SoC: MediaTek MT7621A
- RAM: DDR3 128 MiB
- Flash Memory: NAND 128 MiB (Spansion S34ML01G200TF100)
- Wi-Fi: MediaTek MT7603E
- Wi-Fi: MediaTek MT7615
- Ethernet: 5x 10 Mbps / 100 Mbps / 1000 Mbps (1x WAN, 4x LAN)

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.
