1562847cde ramips: add support for TP-Link EX220 v1
This device is very similar, if not identical, to the TP-Link AX23 v1
but is targeted at service providers and features a completely different
flash layout.

Hardware
--------

CPU:    MediaTek MT7621 DAT
RAM:    128MB DDR3 (integrated)
FLASH:  16MB SPI-NOR
WiFi:   MediaTek MT7905 + MT7975 (2.4 / 5 DBDC) 802.11ax
SERIAL: 115200 8N1
        LEDs - (3V3 - GND - RX - TX) - ETH ports

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

Flashing is only possible via a serial connection using the sysupgrade
image; the factory image must be signed. You can flash the sysupgrade
image directly through the U-Boot console, or preferably, by booting the
initramfs image and flashing with the sysupgrade command. Follow these
steps for sysupgrade flashing:

1. Establish a UART serial connection.
2. Set up a TFTP server at 192.168.0.2 and copy the initramfs image
   there.
3. Power on the device and press any key to interrupt normal boot.
4. Load the initramfs image using tftpboot.
5. Boot with bootm.
6. If you haven't done so already, back up all stock mtd partitions.
7. Copy the sysupgrade image to the router.
8. Flash OpenWrt through either LuCI or the sysupgrade command. Remember
   not to attempt saving settings.

Revert to stock firmware
------------------------

Flash stock firmware via OEM web-recovery mode. If you don't have access
to the stock firmware image, you will need to restore the firmware
partition backed up earlier.

Web-Recovery
------------

The router supports an HTTP recovery mode:

1. Turn off the router.
2. Press the reset button and power on the device.
3. When all LEDs start flashing, release reset and quickly press it
   again.

The interface is reachable at 192.168.0.1 and supports installation of
the OEM factory image. Note that flashing OpenWrt this way is not
possible, as mentioned above.

 - Switch: 1 WAN, 4 LAN (Gigabit)
 - Buttons: Reset, WPS
 - LEDs: System, Wan, Lan 1-4, WiFi 2.4G, WiFi 5G, WPS
 - Power: DC 12V 1A tip positive

Download and flash the manufacturer's built OpenWRT image available at
http://www.cudytech.com/openwrt_software_download
Install the new OpenWRT image via luci (System -> Backup/Flash firmware)
Be sure to NOT keep settings. The force upgrade may need to be checked
due to differences in router naming conventions.

Cudy WR1300 v3 differs from v2 only in swapped WiFi chip PCIe slots. Common
nodes are extracted to .dtsi and new v2 and v3 dts are created.

Cudy WR1300 v2 dts now contains ieee80211-freq-limit.

The same manufacturer's built OpenWRT image is provided for both v2 and v3
devices as a step in installing, but for proper WiFi functionality,
a separate build is required.

Recovery:
 - Loads only signed manufacture firmware due to bootloader RSA verification
 - serve tftp-recovery image as /recovery.bin on 192.168.1.88/24
 - connect to any lan ethernet port
 - power on the device while holding the reset button
 - wait at least 8 seconds before releasing reset button for image to
   download
 - See http://www.cudytech.com/newsinfo/547425.html

Backported from branch main to 23.05.

ramips: RT1800: fix invalid octal number error
This commit removes the padded zeros in the date formatting.
The padded zeros from the date command causes the numbers
to be interpreted as an octal number by printf. Months, days,
and years with the number 08 or 09 raise an error in printf as an
"invalid octal number" and get interpreted as a zero.

- Flash:    16 MiB SPI NOR (EN25QH128A-104HIP)
- Ethernet: 4x 10/100/1000 Mbps (SOC's built-in switch)
- Wi-Fi:    2x2:2 2.4/5 GHz (MT7905DAN + MT7975DN)
            (MT7905DAN doesn't support background DFS scan/BT)
- LED:      6x green, 1x green/red
- Buttons:  2x (reset, WPS)
- Antenna:  4x external, non-detachable omnidirectional
- UART:     1x 4-pin (2.54 mm pitch, J4, not populated)
- Power:    12 V DC/1 A (DC jack)

MAC addresses:

LAN:     00:c0:ca:xx:xx:4e (factory 0x4, +2)
WAN:     00:c0:ca:xx:xx:4f (factory 0x4, +3)
2.4 GHz: 00:c0:ca:xx:xx:4c (factory 0x4, device's label)
5 GHz:   00:c0:ca:xx:xx:4c (factory 0xa)

Flash instructions for web-based U-Boot recovery:

1. Power the device with WPS button pressed and wait around 10 seconds.
2. Setup static IP 192.168.1.2/24 on your PC.
3. Go to 192.168.1.1 in browser and upload 'recovery' image.

The device runs LEDE 17.01 (kernel 4.4.x) based firmware with 'failsafe'
mode available which allows alternative upgrade method:

1. Run device in 'failsafe' mode and change password for default user.
2. SSH to the device, transfer 'sysupgrade' image and perform upgrade
   in forced mode, without preserving settings: 'sysupgrade -n -F ...'.

Other notes:

If you own early version of this device, the vendor firmware might
refuse OpenWrt image because of missing custom header. In that case,
ask vendor's customer support for stock firmware without custom header
support/requirement.

cd878b1b55 ramips: mt7621: add TP-Link EAP613 v1
The TP-Link EAP613 v1 is a ceiling-mount 802.11ax access point. It can
be powered via PoE or a DC barrel connector (12V). Connecting to the
UART requires fine soldering and careful manipulation of any soldered
wires.

Device details:
  * SoC: MT7621AT
  * Flash: 16 MiB SPI NOR
  * RAM: 256 MiB DDR3L
  * Wi-Fi:
    * MT7905DA + MT7975D: 2.4 GHz + 5 GHz (DBDC), 2x2:2
    * Two stamped metal antennas (ANT1, ANT2)
    * One PCB antenna (ANT3)
    * One unpopulated antenna (ANT4)
  * Ethernet:
    * 1× 10/100/1000 Mbps port with PoE
  * LEDs:
    * Array of four blue LEDs with one control line
  * Buttons:
    * Reset
  * Board test points:
    * UART: next to CPU RF-shield and power circuits
    * JTAG: under CPU RF-shield (untested)
  * Watchdog: 3PEAK TPV706 (not implemented)

  Althought three antennas are populated, the MT7905DA does not support
  the additional Rx chain for background DFS detection (or Bluetooth)
  according to commit 6cbcc34f50 ("ramips: disable unsupported
  background radar detection").

MAC addresses:
  * LAN: 48:22:54:xx:xx:a2 (device label)
  * WLAN 2.4 GHz: 48:22:54:xx:xx:a2
  * WLAN 5 GHz: 48:22:54:xx:xx:a3

  The radio calibration blob stored in flash also contains valid MAC
  addresses for both radio bands (OUI 00:0c:43).

Factory install:
  1. Enable SSH on the device via web interface
  2. Log in with SSH, and run `cliclientd stopcs`
  3. Upload -factory.bin image via web interface. It may be necessary to
     shorten the filename of the image to e.g. 'factory.bin'.

Recovery:
  1. Open the device by unscrewing four screws from the backside
  2. Carefully remove board from the housing
  3. Connect to UART (3.3V):
    * Find test points labelled "VCC", "GND", "UART_TX", "UART_RX"
    * Solder wires to test points or connect otherwise. Be careful not
      to damage the PCB e.g. by pulling on soldered wires.
    * Open console with 115200n8 settings
  4. Interrupt bootloader and use tftpboot to start an initramfs:
        setenv ipaddr $DEVICE_IP
        setenv serverip $SERVER_IP
        tftpboot 84000000 openwrt-initramfs-kernel.bin
        bootm

  DO NOT use saveenv to store modified u-boot environment variables. The
  environment is saved at flash offset 0x30000, which erases part of the
  (secondary) bootloader.

  The device uses two bootloader stages. The first stage will load the
  second stage from a uImage stored at flash offset 0x10000. In case of
  a damaged second stage, the first stage should allow uploading a new
  image via y-modem (untested).

- Button: Reset, WPS
- UART: 1:VCC, 2:GND, 3:TX, 4:RX (from LAN port)
  Serial console @ 57600,8n1

Flash instructions:

Connect to serial console and start up the device. As the bootloader got
locked you need to type in a password to unlock U-Boot access.
When you see the following output on the console:

relocate_code Pointer at: 87f1c000

type in the super secure password:

1234567890

Then select TFTP boot from RAM by selecting option 1 in the boot menu.
As Linksys decided to leave out a basic TFTP configuration you need to
set server- & client ip as well as the image filename the device will
search for. You need to use the initramfs openwrt image for the TFTP
boot process.

Once openwrt has booted up, upload the sysupgrade image via scp and run
sysupgrade as normal.

4a043dc9d4 ramips: add factory image for TP-Link EC330-G5u v1
This commit adds factory.bin image for TP-Link EC330-G5u v1. This allows
to install OpenWrt without connecting a serial cable (UART).

Installation using factory image
--------------------------------

Tested with "3.16.0 0.9.1 v6037.0 Build 191016 Rel.30619nb" TP-Link
firmware.

1.  Login to the router web interface (http://192.168.0.1/ by default) and
    save running config to "conf.bin" file
2.  Open configuration file in any TP-Link config editor (e.g.
    https://jahed.github.io/tp-link-config-editor/)
3.  Find "DeviceInfo" section and insert a new string "<Description
    val="Modem Router`telnetd -p 1023 -l login`" />" according to the
    following example:
       <DeviceInfo>
          ...
          <Description val="Modem Router`telnetd -p 1023 -l login`" />
          ...
       </DeviceInfo>
4.  Save configuration file and upload changed configuration using stock
    firmware interface
5.  Login using telnet to IP:192.168.0.1 (Username:admin, password:1234)
6.  Run "cat /proc/mtd | grep mtd7"
       a. If the result is 'mtd7: 03000000 00020000 "rootfs" 03400000',
          then install stock firmware using web interface to toggle booted
          firmware image from "os1" to "os0"
       b. If the result is 'mtd7: 03000000 00020000 "rootfs" 00400000',
          then all is ok, go to the next step
7.  Set up a tftp server with OpenWrt factory.bin image (IP:192.168.0.100
    in this example)
8.  Login using telnet to 192.168.0.1
9.  Download OpenWrt factory.bin image from the tftp server:
       cd /tmp
       tftp -g -r factory.bin 192.168.0.100
10. Write OpenWrt factory.bin image:
       dd if=/tmp/factory.bin of=/dev/mtdblock1
11. Power cycle the router

28df7f7ff2 ramips: mt7621: add support for ZyXEL WSM20
The ZyXEL WSM20 aka Multy M1 is a cheap mesh router system by ZyXEL
based on the MT7621 CPU.

Specifications
==============

SoC: MediaTek MT7621AT (880MHz)
RAM: 256MiB
Flash: 128MiB NAND
Wireless: 802.11ax (2x2 MT7915E DBDC)
Ethernet: 4x 10/100/1000 (MT7530)
Button: 1x WPS, 1x Reset, 1x LED On/Off
LED: 7 LEDs (3x white, 2x red, 2x green)

MAC address assignment
======================

The MAC address assignment follows stock: The label MAC address is the LAN
MAC address, the WAN address is read from flash.

The WiFi MAC addresses are set in userspace to label MAC + 1 and label MAC
+ 2.

Installation (web interface)
============================

The device is cloud-managed, but there is a hidden local firmware upgrade
page in the OEM web interface. The device has to be registered in the
cloud in order to be able to access this page.

The system has a dual firmware design, there is no way to tell which
firmware is currently booted. Therefore, an -initramfs version is flashed
first.

1. Log into the OEM web GUI
2. Access the hidden upgrade page by navigating to
   https://192.168.212.1/gui/#/main/debug/firmwareupgrade
3. Upload the -initramfs-kernel.bin file and flash it
4. Wait for OpenWrt to boot and log in via SSH
5. Transfer the sysupgrade file via SCP
6. Run sysupgrade to install the image
7. Reboot and enjoy

NB: If the initramfs version was installed in RAS2, the sysupgrade script
sets the boot number to the first partition. A backup has to be performed
manually in case the OEM firwmare should be kept.

Installation (UART method)
==========================

The UART method is more difficult, as the boot loader does not have a
timeout set. A semi-working stock firmware is required to configure it:

1. Attach UART
2. Boot the stock firmware until the message about failsafe mode appears
3. Enter failsafe mode by pressing "f" and "Enter"
4. Type "mount_root"
5. Run "fw_setenv bootmenu_delay 3"
6. Reboot, U-Boot now presents a menu
7. The -initramfs-kernel.bin image can be flashed using the menu
8. Run the regular sysupgrade for a permanent installation

Changing the partition to boot is a bit cumbersome in U-Boot, as there is
no menu to select it. It can only be checked using mstc_bootnum. To change
it, issue the following commands in U-Boot:

   nand read 1800000 53c0000 800
   mw.b 1800004 1 1
   nand erase 53c0000 800
   nand write 1800000 53c0000 800

This selects FW1. Replace "mw.b 1800004 1 1" by "mw.b 1800004 2 1" to
change to the second slot.

Back to stock
=============

It is possible to flash back to stock, but a OEM firmware upgrade is
required. ZyXEL does not provide the link on its website, but the link
can be acquired from the OEM web GUI by analyzing the transferred JSON
objects.

It is then a matter of writing the firmware to Kernel2 and setting the
boot partition to FW2:

   mtd write zyxel.bin Kernel2
   echo -ne "\x02" | dd of=/dev/mtdblock7 count=1 bs=1 seek=4 conv=notrunc

Stock flash layout:
```

0x000000fb0000-0x000001000000 : "Private"
```
The kernel partition will be replaced with the OpenWrt image, the other
partitions are left untouched.

"Config2" seems to be the config storage used by the stock firmware.

"Private" is a 320kB empty JFFS2 partition that comes with the stock
firmware. One can get a larger space for OpenWrt by merging it with
"Kernel".

OpenWrt flash layout:
```
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"

0x000000fb0000-0x000001000000 : "private_stock"
```

The OpenWrt image must have 96 bytes of padding in the header.

MAC addresses on OEM firmware:
|      		| location on the flash 	| notes    	|
|------		|-----------------------	|----------	|
| lan (eth2) 	| factory + 0xe000      	| on label 	|
| wan (eth3) 	| factory + 0xe006      	|          	|
| 2.4g (rax0) 	| not on flash          	| lan + 1  	|
| 5g (ra0) 	| not on flash          	| lan + 2  	|

Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
the u-boot-env partition, but they are not used. OpenWrt calculates
Wifi Mac addresses based on the LAN Mac.

Flash and test instructions:
Flash the encrypted image (available in the OpenWrt forum) through the
stock D-Dink web interface.

1. Open the case, and solder the 4-pin header near the WAN port.
2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
the settings mentioned above.
4. Setup a TFTP server on your PC that can serve
`xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
5. Connect any LAN port to your PC and set a static IPv4 address to
192.168.0.101 (netmask 255.255.255.0).
6. Power on the device and keeps pressing 1 until you see the prompt.
7. Use default IP addresses and enter the file name accordingly, then hit
enter.
8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
you need to change your PC network adapter to use DHCP in order to access
LUCI.
9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
You can try OpenWrt without having to overwrite the stock firmware, a
reboot clears all changes.
10. Optionally, backup the stock firmware (the "firmware" partition) in
Luci.
11. To permantly install OpenWrt to the device , click
on "System -> Backup/Flash Firmware" in Luci and flash
`xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`

Known problems:
* WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
you need to config it manually in LUCI.

* If you see jffs2 related warnings/errors after updating from the stock
web interface, you need to do a reset in LUCI. The error will be gone after
a cold reboot.

79bd0172ca mt7621: move uboot-envtools to DEFAULT_PACKAGES
Several devices depend on fw_printenv during sysupgrade.  Make sure
it always is present in all images, including initramfs images built

68004f1942 ramips: add alternative device name for Wiflyer WF3526-P
Wiflyer WF3526-P and Zbtlink ZBT-WE1326 have the same circuit design.
Installing the misunderstading firmware of ZBT-WE3526 will cause Wi-Fi
not work due to allocate the wrong pcie port. Add alternative name to
help users easily build or download the correct firmware.

d4c63c7786 ramips: add support for TP-Link Deco M4R v4
This commit adds support for the V4 hardware revision of the Deco M4R.
V4 is a complete overhaul of the hardware compared to V1 and V2,
and is much more similar to the Archer C6 V3 and C6U V1.

Specifications:

  SoC: MediaTek MT7621AT (2 cores at 880 MHz, 4 threads)
  RAM: Kingston D1216ECMDXGJD (256 MB)
  Wireless 2.4 GHz: MediaTek MT7603EN
  Wireless 5 GHz: MediaTek MT7613BEN
  Flash: 16 MB SPI NOR

Installation:

Flash the *-factory.bin image in the U-Boot recovery webserver.
You can trigger this webserver by holding the reset button until the LED
flashes yellow, or by hooking up to serial pads on the board (clearly
labeled GND, RX and TX) and pressing `x` early in boot.

Once the factory image has been flashed, you can use the regular upgrade
procedure with sysupgrade images for subsequent flashes.

39e4f03fd3 ramips: mt7621: add support for Xiaomi Mi Router 4A Gigabit v2
Device is the same as Xiaomi Mi Router 4A Gigabit, except of:
- 5G WiFi is MT7663
- addresses of leds, wifi and eth ports are slightly changed

Specs:
  SoC:  MT7621
  CPU:  2 x 880 MHz
  ROM:  16 MB
  RAM:  128 MB
  WLAN: MT7603, MT7663

MAC addresses:
  WAN     ****  factory 0xe006 (label)
  LAN     *:f7  factory 0xe000
  2.4 GHz *:f8  factory 0x0000+0x4 (mtd-eeprom+0x4)
  5 GHz   *:f9  factory 0x8000+0x4 (mtd-eeprom+0x4)

Installation:

Factory firmware is based on a custom OpenWrt 17.x.
Installation is the same as for Xiaomi Mi Router 4A Gigabit.

Probably the easiest way to install is to use the script from
this repository: https://github.com/acecilia/OpenWRTInvasion/pull/155

In a more advanced case, you can do everything yourself:
- gain access to the device through one of the exploits described
  in the link above
- upload sysupgrade image to /tmp
- overwrite stock firmware:
  # mtd -e OS1 -r write /tmp/sysupgrade.bin OS1

Recovery:

Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit.
Possible options can be found here:
https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition

One of the ways is to use another router with OpenWrt:
- connect both routers by their LAN ports
- download stock firmware from [1]
- place it inside /tmp/test.bin on the main router
- configure PXE/TFTP on the main router
- power off 4Av2, hold Reset button, power on
- as soon as image download via TFTP starts, Reset can be released
- blinking blue wan LED will indicate the end of the flashing process,
  now router can be rebooted
