Notes:

- currently, mt7615e driver in mt76 doesn't fully support MT7613
  (MT7663) wifi chip
  - the eeprom data in flash is not used by mt7615e driver and the
    driver reports the tx-power up to 3dBm
  - the correct MAC address for MT7613BE in eeprom data cannot be
    assigned to the phy

- last 0x80000 (512 KiB) in NAND flash is not used on stock firmware

- stock firmware requires "customized uImage header" (called as "combo
  image") by MSTC (MitraStar Technology Corp.), but U-Boot doesn't

  - uImage magic ( 0x0 - 0x3 ) : 0x434F4D43 ("COMC")
  - header crc32 ( 0x4 - 0x7 ) : with "data length" and "data crc32"
  - image name   (0x20 - 0x37) : model ID and firmware versions

fb4d7a9680 ramips: add support for Ubiquiti UniFi 6 Lite
Hardware
--------
MediaTek MT7621AT
256M DDR3
32M SPI-NOR
MediaTek MT7603 2T2R 802.11n 2.4GHz
MediaTek MT7915 2T2R 802.11ax 5GHz

Not Working
-----------
 - Bluetooth (connected to UART3)

UART
----

UART is located in the lower left corner of the board. Pinout is

0 - 3V3 (don't connect)
1 - RX
2 - TX
3 - GND

Console is 115200 8N1.

Boot
----

1. Connect to the serial console and connect power.

2. Double-press ESC when prompted

3. Set the fdt address

   $ fdt addr $(fdtcontroladdr)

4. Remove the signature node from the control FDT

   $ fdt rm /signature

5. Transfer and boot the OpenWrt initramfs image to the device.
   Make sure to name the file C0A80114.img and have it reachable at
   192.168.1.1/24

   $ tftpboot; bootm

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

1. Connect to the booted device at 192.168.1.20 using username/password
   "ubnt".

2. Update the bootloader environment.

   $ fw_setenv devmode TRUE
   $ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
     fdt rm /signature; bootubnt"
   $ fw_setenv bootcmd "run boot_openwrt"

3. Transfer the OpenWrt sysupgrade image to the device using SCP.

4. Check the mtd partition number for bs / kernel0 / kernel1

   $ cat /proc/mtd

5. Set the bootselect flag to boot from kernel0

   $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4

6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1

   $ dd if=openwrt.bin of=/dev/mtdblock6
   $ dd if=openwrt.bin of=/dev/mtdblock7

7. Reboot the device. It should boot into OpenWrt.

Below are the original installation instructions prior to the discovery
of "devmode=TRUE". They are not required for installation and are
documentation only.

The bootloader employs signature verification on the FIT image
configurations. This way, booting unauthorized image without patching
the bootloader is not possible. Manually configuring the bootcmd in the
U-Boot envronment won't work, as this is restored to the default value
if modified.

The bootloader is made up of three different parts.

1. The SPL performing early board initialization and providing a XModem
   recovery in case the PBL is missing

2. The PBL being the primary U-Boot application and containing the
   control FDT. It is LZMA packed with a uImage header.

3. A Ubiquiti standalone U-Boot application providing the main boot
   routine as well as their recovery mechanism.

In a perfect world, we would only replace the PBL, as the SPL does not
perform checks on the PBLs integrity. However, as the PBL is in the same
eraseblock as the SPL, we need to at least rewrite both.

The bootloader will only verify integrity in case it has a "signature"
node in it's control device-tree. Renaming the signature node to
something else will prevent this from happening.

Warning: These instructions are based on the firmware intially
shipped with the device and potentially brick your device in a way it
can only be recovered using a SPI flasher.

Only (!) proceed if you understand this!

1. Extract the bootloader from the U-Boot partition using the OpenWrt
   initramfs image.

2. Split the bootloader into it's 3 components:

   $ dd if=bootloader.bin of=spl.bin bs=1 skip=0 count=45056
   $ dd if=bootloader.bin of=pbl.uimage bs=1 skip=45056 count=143360
   $ dd if=bootloader.bin of=ubnt.uimage bs=1 skip=188416

3. Strip the uImage header from the PBL

   $ dd if=pbl.uimage of=pbl.lzma bs=64 skip=1

4. Decompress the PBL

   $ lzma -d pbl.lzma --single-stream

   The decompressed PBL sha256sum should be
   d8b406c65240d260cf15be5f97f40c1d6d1b6e61ec3abed37bb841c90fcc1235

5. Open the decompressed PBL using your favorite hexeditor. Locate the
   control FDT at offset 0x4CED0 (0xD00DFEED). At offset 0x4D5BC, the
   label for the signature node is located. Rename the "signature"
   string at this offset to "signaturr".

   The patched PBL sha256sum should be
   d028e374cdb40ba44b6e3cef2e4e8a8c16a3b85eb15d9544d24fdd10eed64c97

6. Compress the patched PBL

   $ lzma -z pbl --lzma1=dict=67108864

   The resulting pbl.lzma file should have the sha256sum
   7ae6118928fa0d0b3fe4ff81abd80ecfd9ba2944cb0f0a462b6ae65913088b42

7. Create the PBL uimage

   $ SOURCE_DATE_EPOCH=1607909492 mkimage -A mips -O u-boot -C lzma
     -n "U-Boot 2018.03 [UniFi,v1.1.40.71]" -a 84000000 -e 84000000
     -T firmware -d pbl.lzma patched_pbl.uimage

   The resulting patched_pbl.uimage should have the sha256sum
   b90d7fa2dcc6814180d3943530d8d6b0d6a03636113c94e99af34f196d3cf2ce

8. Reassemble the complete bootloader

   $ dd if=patched_pbl.uimage of=aligned_pbl.uimage bs=143360 count=1
     conv=sync
   $ cat spl.bin > patched_uboot.bin
   $ cat aligned_pbl.uimage >> patched_uboot.bin
   $ cat ubnt.uimage >> patched_uboot.bin

   The resulting patched_uboot.bin should have the sha256sum
   3e1186f33b88a525687285c2a8b22e8786787b31d4648b8eee66c672222aa76b

9. Transfer your patched bootloader to the device. Also install the
   kmod-mtd-rw package using opkg and load it.

   $ insmod mtd-rw.ko i_want_a_brick=1

   Write the patched bootloader to mtd0

   $ mtd write patched_uboot.bin u-boot

10. Erase the kernel1 partition, as the bootloader might otherwise
    decide to boot from there.

    $ mtd erase kernel1

11. Transfer the OpenWrt sysupgrade image to the device and install
    using sysupgrade.

In the future, the MT7621 UniFi6 family can be supported by a single
OpenWrt image.

7a181a65f2 treewide: fix initramfs detection
Commit "initramfs: switch to tmpfs to fix ujail" switched initramfs to
now use tmpfs, it causes $(rootfs_type) to now return tmpfs when
running initramfs image instead of being empty.

This broke initramfs detection which is required so that when installing
on MikroTik devices firmware partition would first get erased fully
before writing.

So, lets test for $(rootfs_type) returning "tmpfs" instead.

a51e46e543 ramips: add Xiaomi Mi Router 4A Gigabit explicitly
This device has previously been supported by the image
for Xiaomi Mi Router 3G v2. Since this is not obvious, the
4A is marketed as a new major revision and it also seems to
have a different bootloader, this will be both more tidy and
more helpful for the users.

Apart from that, note that there also is a 100M version of
the device that uses mt7628 platform, so a specifically named
image will also prevent confusion in this area.

Specifications:

- SoC:      MediaTek MT7621
- Flash:    16 MiB NOR SPI
- RAM:      128 MiB DDR3
- Ethernet: 3x 10/100/1000 Mbps (switched, 2xLAN + WAN)
- WIFI0:    MT7603E 2.4GHz 802.11b/g/n
- WIFI1:    MT7612E 5GHz 802.11ac
- Antennas: 4x external (2 per radio), non-detachable
- LEDs:     Programmable "power" LED (two-coloured, yellow/blue)
            Non-programmable "internet" LED (shows WAN activity)
- Buttons:  Reset

Installation:

Bootloader won't accept any serial input unless "boot_wait" u-boot
environment variable is changed to "on".

Vendor firmware won't accept any serial input until "uart_en" is
set to "1".

Using the https://github.com/acecilia/OpenWRTInvasion exploit you
can gain access to shell to enable these options:

To enable uart keyboard actions - 'nvram set uart_en=1'
To make uboot delay boot work - 'nvram set boot_wait=on'
Set boot delay to 5 - 'nvram set bootdelay=5'

Then run 'nvram commit' to make the changes permanent.

Once in the shell (following the OpenWRTInvasion instructions) you
can then run the following to flash OpenWrt and then reboot:

'cd /tmp; curl https://downloads.openwrt.org/...-sysupgrade.bin
  --output firmware.bin; mtd -e OS1 -r write firmware.bin OS1'

2230fe3922 ramips: remove set_wifi_led function in 01_leds
While we mostly use the ucidef_set_led_* functions directly in 01_leds
we still have the set_wifi_led function in parallel for several old
devices. This is not only inconsistent with the other definitions,
it also links to the wlan0 interface instead of using a phy trigger
which would be independent of the interface name (and is used for
all newer devices anyway). Apart from that, the standard names
"wifi" and "wifi-led" are not very helpful in a world with different
radio bands either.

Thus, this patch removes the set_wifi_led function and puts the
relevant commands into the cases explicitly. This makes the
mechanism used more evident and will hopefully lead to some future
improvements or at least prevent some copy-pasting of the old
setups.

ed5933beb6 ramips: remove option to set WiFi LED via aliases
In ramips, it's not common to use an alias for specifying the WiFi
LED; actually only one device uses this mechanism (TL-WR841N v14).

Particularly since the WiFi LEDs are typically distinguished between
2.4G and 5G etc. it is also not very useful for this target.

Thus, this patch removes the setup lines for this mechanism and
converts the TL-WR841N v14 to the normal setup.

c846dd91f0 ramips: remove model name from LED labels
Like in the previous patch for ath79 target, this will remove the
"devicename" from LED labels in ramips as well.

The devicename is removed in DTS files and 01_leds, consolidation
of definitions into DTSI files is done where (easily) possible,
and migration scripts are updated.

For the latter, all existing definitions were actually just
devicename migrations anyway. Therefore, those are removed and
a common migration file is created in target base-files. This is
actually another example of how the devicename removal makes things
easier.

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.

        UART2: J12 header, located on the right side of
               the board.
* USB: One USB3 port.
* I2C: J9 header, located below the top heatsink.

Backup the OEM Firmware:
-----------------------

There isn't any firmware released for the WL-WN531A6 on
the Wavlink web site. Reverting back to the OEM firmware is
not possible unless we have a backup of the original OEM
firmware.

The OEM firmware is stored on /dev/mtd4 ("Kernel").

  1) Plug a FAT32 formatted USB flash drive into the USB port.
  2) Navigate to "Setup->USB Storage". Under the "Available
     Network folder" you can see part of the mount point of
     the newly mounted flash drive filesystem - e.g "sda1".
     The full mount point is prefixed with "/media", so in
     this case the mount point becomes "/media/sda1".
  3) Go to http://192.168.10.1/webcmd.shtml .
  4) Type the following line in the "Command" input box:

     dd if=/dev/mtd4ro of=/media/sda1/firmware.bin

  5) Click "Apply"
  6) After few seconds, in the text area should appear this
     output:

        30080+0 records in
      30080+0 records out

  7) Type "sync" in the "Command" input box and click "Apply".
  8) At this point the OEM firmware is stored on the flash
     drive as "firmware.bin". The size of the file is 15040 KB.

Installation:
------------

* Flashing instructions (OEM web interface):
The OEM web interface accepts only files with names containing
"WN531A6". It's also impossible to flash the *-sysupgrade.bin
image, so we have to flash the *-initramfs-kernel.bin first and
use the OpenWrt's upgrade interface to write the sysupgrade
image.

  1) Rename openwrt-ramips-mt7621-wavlink_wl-wn531a6-initramfs-kernel.bin
     to WN531A6.bin.
  2) Connect your computer to the one of the LAN ports of the
     router with an Ethernet cable and open http://192.168.10.1
  3) Browse to Setup -> Firmware Upgrade interface.
  4) Upload the (renamed) OpenWrt image - WN531A6.bin.
  5) Proceed with the firmware installation and give the device
     a few minutes to finish and reboot.
  6) After reboot wait for the "WAVLINK" logo on the top cover
     to turn solid blue, and open http://192.168.1.1
  7) Use the OpenWrt's "Flash Firmware" interface to write the
     OpenWrt sysupgrade image:
     openwrt-ramips-mt7621-wavlink_wl-wn531a6-squashfs-sysupgrade.bin

* Flashing instructions (u-boot TFTP):
  1) Configure a TFTP server on your computer and set its IP
     to 192.168.10.100
  2) Rename the OpenWrt sysupgrade image to firmware.bin and
     place it in the root folder of the TFTP server.
  3) Power off the device and connect an Ethernet cable from
     one of its LAN ports your computer.
  4) Press the "Reset" button (and keep it pressed)
  5) Power on the device.
  6) After a few seconds, when the connected port LAN LED stops
     blinking fast, release the "Reset" button.
  7) Flashing OpenWrt takes less than a minute, system will
     reboot automatically.
  8) After reboot the WAVLINK logo on the top cover will indicate
     the current OpenWrt running status (wait until the logo tunrs
     solid blue).

Revert to the OEM Firmware:
--------------------------
* U-boot TFTP:
  Follow "Flashing instructions (u-boot TFTP)" and use the
  "firmware.bin" backup image.

* OpenWrt "Flash Firmware" interface:
  Upload the "firmware.bin" backup image and select "Force update"
  before continuing.

Notes:
-----
* The MAC address shown on the label at the back of the device
is assigned to the 2.4G WiFi adapter.

  MAC addresses assigned by the OEM firmware:
  2.4G: *:XX (label): factory@0x0004
    5G: *:XX + 1    : factory@0x8004
   WAN: *:XX - 1    : factory@0xe006
   LAN: *:XX - 2    : factory@0xe000

* The I2C bus and UART2 are fully functional. The headers are
not populated.

74438d5419 ramips: add support for MikroTik RouterBOARD 760iGS (hEX S)
This patch adds support for the MikroTik RouterBOARD 760iGS router.
It is similar to the already supported RouterBOARD 750Gr3.
The 760iGS device features an added SFP cage, and passive
PoE out on port 5 compared to the RB750Gr3.

https://mikrotik.com/product/hex_s

Specifications:

- SoC: MediaTek MT7621A
- CPU: 880MHz
- Flash: 16 MB
- RAM:  256 MB
- Ethernet: 5x 10/100/1000 Mbps
- SFP cage
- USB port
- microSD slot

Unsupported:

- Beeper (requires PWM driver)
- ZT2046Q (ADS7846 compatible) on SPI as slave 1 (CS1)
  The linux driver requires an interrupt, and pendown GPIO
  These are unknown, and not needed with the touchscreen
  only used for temperature and voltage monitoring.
  ads7846 hwmon:
  temp0 is degrees Celsius
  temp1 is voltage * 32

GPIOs:

- 07:  input passive PoE out (lan5) compatible (Mikrotik) device connected
- 17:  output passive PoE out (lan5) switch

Installation through RouterBoot follows the usual MikroTik method
https://openwrt.org/toh/mikrotik/common

To boot to intramfs image in RAM:

1. Setup TFTP server to serve intramfs image.
2. Plug Ethernet cable into WAN port.
3. Unplug power, hold reset button and plug power in.
   Wait (~25 seconds) for beep and then release reset button.
   The SFP LED will be lit in RouterBoot, but will not be lit in OpenWRT.
4. Wait for a minute. Router should be running OpenWrt,
   check by plugging in to port 2-5 and going to 192.168.1.1.

To install OpenWrt to flash:

1. Follow steps above to boot intramfs image in RAM.
2. Flash the sysupgrade.bin image with web interface or sysupgrade.
3. Once the router reboots you will be running OpenWrt from flash.

OEM firmware differences:

- RouterOS assigns a different MAC address for each port
- The first address (E01 on the sticker) is used for wan (ether1 in OEM).
- The next address is used for lan2.
- The last address (E06 on the sticker) is used for sfp.

1eac573b53 ramips: mt7621: implement compatibility version for DSA migration
This implements the newly introduced compat-version to prevent
broken upgrade between swconfig and DSA for ramips' mt7621 subtarget.

In order to make the situation more transparent for the user, and
to prevent large switch-cases for devices, it is more convenient to
have the entire subtarget 1.1-by-default. This means that new devices
will be added with 1.1 from the start, but in contrast we don't need
to switch them in board.d files. Apart from that, users that manually
backport devices to 19.07 with swconfig will have an equivalent
upgrade experience to officially supported devices.

Since DSA support on mt7621 is out for a while already, this applies
the same uci-defaults workaround for early adopters as already
done for kirkwood and mvebu in previous commits.

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

	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

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.

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.

RAM:   128MB
FLASH: 16MB NOR (Macronix MX25L12805D)
ETH:   1x 10/100/1000 Mbps Ethernet (MT7530)
WIFI:
  - 2.4GHz: 1x MT7615 (4x4:4)

LEDS:
  - 1x Green led (Power)
  - 1x Green-Amber-Red led (Wifi)
UART:

Everything works correctly.

Installation
------------
Flash the factory image directly from OEM web interface.
(You can login using these credentials: admin/1234)

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)

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.

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).

intended, but tried over and over since the non-zero exit prevents the
script from being deleted.

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)
Ie. wget https://yourip/busybox-mipsel -O /tmp/busybox
chmod a+x /tmp/busybox
/tmp/busybox telnetd -l /bin/sh

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.

5e50515fa6 ramips/mt7621: mikrotik: don't use mtd-mac-address in DTS
As evidenced here[1] the device MAC address can be stored at a random
offset in the hard_config partition. Rely on sysfs to update the MAC
address correctly.

Adjust config so that WAN is base MAC and LAN is base MAC +1 to better
match label and vendor OS.

a10537f674 ramips: fix MikroTik 750Gr3 ports MAC addresses
According to a user in OpenWrt forum, on RouterOS the MAC addresses are
ether1(WAN) = MAC
ether2(LAN2) = MAC+1
ether3(LAN3) = MAC+2
etc.

Fix the MAC addresses in OpenWrt.

ramips: enable SFP port for Ubiquiti ER-X-SFP
SFP cage of this device is connected via a AT8031 phy to port 5 of the switch.
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!
