The following devices have a Winbond W25Q256FV flash chip,
which does not have the RESET pin enabled by default,
and otherwise would require setting a bit in a status register.

Before moving to Linux 5.4, we had the patch:
0053-mtd-spi-nor-add-w25q256-3b-mode-switch.patch
which kept specific flash chips with explicit 3-byte and 4-byte address modes
to stay in 3-byte address mode while idle (after an erase or write)
by using a custom flag SPI_NOR_4B_READ_OP that was part of the patch.

this was obsoleted by the patch:
481-mtd-spi-nor-rework-broken-flash-reset-support.patch
which uses the newer upstream flag SNOR_F_BROKEN_RESET
for devices with a flash chip that cannot be hardware reset with RESET pin
and therefore must be left in 3-byte address mode when idle.

The new patch requires that the DTS of affected devices
have the property "broken-flash-reset", which was not yet added for most of them.

This commit adds the property for remaining affected devices in ramips target,
specifically because of the flash chip model.

However, it is possible that there are other devices
where the flash chip uses an explicit 4-byte address mode
and the RESET pin is not connected to the SOC on the board,
and those DTS would also need this property.

Specifications:
- SoC: MT7621DAT (880MHz, 2 Cores)
- RAM: 128 MB
- Flash: 128 MB NAND
- Ethernet: 5x 1GiE MT7530
- WiFi: MT7603/MT7613
- USB: 1x USB 3.0

This is another MT7621 device, very similar to other Linksys EA7300
series devices.

Installation:

Upload the generated factory.bin image via the stock web firmware
updater.

Reverting to factory firmware:

Like other EA7300 devices, this device has an A/B router configuration
to prevent bricking.  Hard-resetting this device three (3) times will
put the device in failsafe (default) mode.  At this point, flash the
OEM image to itself and reboot.  This puts the router back into the 'B'
image and allows for a firmware upgrade.

Troubleshooting:

If the firmware will not boot, first restore the factory as described
above.  This will then allow the factory.bin update to be applied
properly.

RAISECOM MSG1500 X.00 is a 2.4/5 GHz band 11ac (Wi-Fi 5) router.
Apart from the general model, there are two ISP customized models:
China Mobile and China Telecom.

Specifications:

- SoC: Mediatek MT7621AT
- RAM: 256MiB DDR3
- Flash: 128MiB NAND
- Ethernet: 5 * 10/100/1000Mbps: 4 * LAN + 1 * WAN
  - Switch: MediaTek MT7530 (SoC)
- WLAN: 1 * MT7615DN Dual-Band 2.4GHz 2T2R (400Mbps) 5GHz 2T2R (867Mbps)
- USB: 1 * USB 2.0 port
- Button: 1 * RESET button, 1 * WPS button, 1 * WIFI button
- LED: blue color: POWER, WAN, WPS, 2.4G, 5G, LAN1, LAN2, LAN3, LAN4, USB
- UART: 1 * serial port header (4-pin)
- Power: DC 12V, 1A
  - Switch: 1 * POWER switch

MAC addresses as verified by vendor firmware:

use   address             source
LAN   C8:XX:XX:3A:XX:E7   Config   "protest_lan_mac"  ascii  (label)
WAN   C8:XX:XX:3A:XX:EA   Config   "protest_wan_mac"  ascii
5G    C8:XX:XX:3A:XX:E8   Factory  "0x4"              hex
2.4G  CA:XX:XX:4A:XX:E8   [not on flash]

The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:

       5g                 2.4g         increment
 C8:XX:XX:90:XX:C3  CA:XX:XX:C0:XX:C3  0x30
 C8:XX:XX:3A:XX:08  CA:XX:XX:4A:XX:08  0x10
 C8:XX:XX:3A:XX:E8  CA:XX:XX:4A:XX:E8  0x10

Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.

Notes:

1. The vendor firmware allows you to connect to the router by telnet.
   (known version 1.0.0 can open telnet.)
   There is no official binary firmware available.
   Backup the important partitions data:
   "Bootloader", "Config", "Factory", and "firmware".
   Note that with the vendor firmware the memory is detected only 128MiB
   and the last 512KiB in NAND flash is not used.

2. The POWER LED is default on after press POWER switch.
   The WAN and LAN1 - 4 LEDs are wired to ethernet switch.
   The WPS LED is controlled by MT7615DN's GPIO.
   Currently there is no proper way to configure it.

3. At the time of adding support the wireless config needs to be set up
   by editing the wireless config file:

 * Setting the country code is mandatory, otherwise the router loses
   connectivity at the next reboot. This is mandatory and can be done
   from luci. After setting the country code the router boots correctly.
   A reset with the reset button will fix the issue and the user has to
   reconfigure.

 * This is minor since the 5g interface does not come up online although
   it is not set as disabled. 2 options here:

   1- Either run the "wifi" command. Can be added from LuCI in system -
      startup - local startup and just add wifi above "exit 0".

   2- Or add the serialize option in the wireless config file as shown
      below. This one would work and bring both interfaces automatically
      at every boot:

      config wifi-device 'radio0'
          option serialize '1'

      config wifi-device 'radio1'
          option serialize '1'

Flash instructions using initramfs image:

1. Press POWER switch to power down if the router is running.

2. Connect PC to one of LAN ports, and set
   static IP address to "10.10.10.2", netmask to "255.255.255.0",
   and gateway to "10.10.10.1" manually on the PC.

3. Push and hold the WIFI button, and then power up the router.
   After about 10s (or you can call the recovery page, see "4" below)
   you can release the WIFI button.
   There is no clear indication when the router
   is entering or has entered into "RAISECOM Router Recovery Mode".

4. Call the recovery page for the router at "http://10.10.10.1".
   Keep an eye on the "WARNING!! tip" of the recovery page.
   Click "Choose File" to select initramfs image, then click "Upload".

5. If image is uploaded successfully, you will see the page display
   "Device is upgrading the firmware... %".
   Keep an eye on the "WARNING!! tip" of the recovery page.
   When the page display "Upgrade Successfully",
   you can set IP address as "automatically obtain".

6. After the rebooting (PC should automatically obtain an IP address),
   open the SSH connection, then download the sysupgrade image
   to the router and perform sysupgrade with it.

Flash back to vendor firmware:

 See "Flash instructions 1 - 5" above.
 The only difference is that in step 4
 you should select the vendor firmware which you backup.

The UniFi 6 Lite has two MAC addresses for the 2.4 and 5GHz radio in
it's EEPROM partition.

On my unit these are

F4 92 BF A0 BB 6F
F6 92 BF A0 BB 6F

The problem with these is that mac80211 increases the first octet by
2, which leads to conflicting MAC addresses between radios.

Work around this problem for now by increasing the last octet by 1 on
the 5 GHz radio.

Ubiquiti increases the last octet by 2 for each subsequent VAP created
per radio. Ideally we should do the same, however this functionality is
currently lacking from mac80211.

Zbtlink ZBT-WG1602 is a Wi-Fi router intendent to use with WWAN
(UMTS/LTE/3G/4G) modems. The router board offsers a couple of miniPCIe
slots with USB and SIM only and another one pure miniPCIe slot as well
as five Gigabit Ethernet ports (4xLAN + WAN).

Specification:

* SoC: MT7621A
* RAM: 256/512 MiB
* Flash: 16/32 MiB (SPI NOR)

* WLAN 2GHz: MT7603EN (.11n, MIMO 2x2)
* WLAN 5GHz: MT7612EN (.11ac, MIMO 2x2)
* WLAN Ants: detachable x2, shared by 2GHz & 5GHz radios
* miniPCIe: 2x slots with USB&SIM + 1x slot with regular PCIe bus
* WWAN Ants: detachable x4
* External storage: microSD (SDXC) slot
* USB: 2.0 Type-A port
* LED: 11 (5 per Eth phy, 3 SoC controlled, 2 WLAN 2/5 controlled, 1
       power indicator)
* Button: 1 (reset)
* UART: console (115200 baud)
* Power: DC jack (12 V / 2.5 A)

Additional HW information:

* SoC USB port #1 is shared by internal miniPCIe slot and external
  Type-A USB port, USB D+/D- lines are toggled between ports using a
  GPIO controlled DPDT switch.
* Power of the USB enabled miniPCIe slots can be individually controlled
  using dedicated GPIO lines.
* Vendor firmware feeds the external watchdog with 1s pulses. GPIO
  watchdog driver is able to either generate a 1us pulses or toggle the
  output line. 1us is not enough for the external watchod timer, so
  the line toggling driver mode is utilized.

Installation:

Vendor's firmware is OpenWrt (LEDE) based, so the sysupgrade image can
be directly used to install OpenWrt. Firmware must be upgraded using the
'force' and 'do not save configuration' command line options (or
correspondig web interface checkboxes) since the vendor firmware is from

The same situation was there. It is required to enable all phy ports.
This is fragment of stock bootlog:

switch reg write_athr offset=8c, value=2b0
switch reg write_athr offset=88, value=2b0
switch reg write_athr offset=84, value=2b0
switch reg write_athr offset=80, value=2b0

This patch adds proper registers configuration ar8337 initvals.
0x2b0 value causes force flow control configuration, 0x1200 was used
instead (flow control config auto-neg with phy). [1]

'cpc' and 'mc' nodes correspond with the MIPS 'Cluster Power Controller'
and 'MIPS Common Device Memory Map' which are present in some MIPS related
boards. There is already bindings documentation for these two located in:
- Documentation/devicetree/bindings/power/mti,mips-cpc.yaml
- Documentation/devicetree/bindings/bus/mti,mips-cdmm.yaml

Hence, properly update compatible strings and align nodes with already
mainlined bindings documentation. Also, move their definition to a proper
place since both of them are not related with the palmbus at all.

- RAM: 256 MB (DDR3)
- Flash: 32 MB SPI NOR 44MHz
- Switch: 1 WAN, 4 LAN (Gigabit)
- LEDs: 1 WAN, 4 LAN (controlled by PHY)
- USB Ports: 1 x USB2, 1 x USB3

Installation:
Update openWRT firmware using internal GNUBEE uboot:
https://github.com/gnubee-git/GnuBee-MT7621-uboot

By HTTP: Initial uboot address is http://10.10.10.123, your address
needs to be 10.10.10.x, and mask 255.255.255.0.
By TFTP: Uboot is in client mode, the address of the firmware must
be tftp://10.10.10.3/uboot.bin



Recovery:
Manufacturer provides MTK OpenWrt 14.07 source code, compile then
flash it by uboot.
HLK-7621A is a stamp hole package module for embedded development,
users have to design IO boards to use it.

MAC addresses:
- u-boot-env contains a placeholder address:
  > mtd_get_mac_ascii u-boot-env ethaddr
  03:17:73:ab:cd:ef
- phy0 gets a valid-looking address:
  > cat /sys/class/ieee80211/phy0/macaddress
  f8:62:aa:**:**:a8
- Calibration data for &pcie2 contains a valid address, however the
  zeros in the right half look like it's not real:
  8c:88:2b:00:00:1b
- Since it's an evaluation board and there is no solid information
  about the MAC address assignment, the ethernet MAC address is left random.

This commit adds support for Xiaomi MiWiFi 3C device.

Xiaomi MiWifi 3C has almost the same system architecture
as the Xiaomi Mi WiFi Nano, which is already officially
supported by OpenWrt.

The differences are:

 - Numbers of antennas (4 instead of 2). The antenna management
   is done via the µC. There is no configuration needed in the
   software code.
 - LAN port assignments are different. LAN1 and WAN are
   interchanged.

OpenWrt Wiki: https://openwrt.org/toh/xiaomi/mir3c

OpenWrt developers forum page:
https://forum.openwrt.org/t/support-for-xiaomi-mi-3c

Specifications:

 - CPU: MediaTek MT7628AN (575MHz)
 - Flash: 16MB
 - RAM: 64MB DDR2
 - 2.4 GHz: IEEE 802.11b/g/n with Integrated LNA and PA
 - Antennas: 4x external single band antennas
 - WAN: 1x 10/100M
 - LAN: 2x 10/100M
 - LED: 1x amber/blue/red. Programmable
 - Button: Reset

MAC addresses as verified by OEM firmware:

use address source
LAN *:92 factory 0x28
WAN *:92 factory 0x28
2g *:93 factory 0x4

OEM firmware uses VLAN's to create the network interface for WAN and LAN.

Bootloader info:
The stock bootloader uses a "Dual ROM Partition System".
OS1 is a deep copy of OS2.
The bootloader start OS2 by default.
To force start OS1 it is needed to set "flag_try_sys2_failed=1".

How to install:
1- Use OpenWRTInvasion to gain telnet, ssh and ftp access.
   https://github.com/acecilia/OpenWRTInvasion


   (IP: 192.168.31.1 - Username: root - Password: root)
2- Connect to router using telnet or ssh.
3- Backup all partitions. Use command  "dd if=/dev/mtd0 of=/tmp/mtd0".
   Copy /tmp/mtd0 to computer using ftp.
4- Copy openwrt-ramips-mt76x8-xiaomi_miwifi-3c-squashfs-sysupgrade.bin
   to /tmp in router using ftp.
5- Enable UART access and change start image for OS1.
```
nvram set uart_en=1
nvram set flag_last_success=1
nvram set boot_wait=on
nvram set flag_try_sys2_failed=1
nvram commit
```
6- Installing Openwrt on OS1 and free OS2.
```
mtd erase OS1
mtd erase OS2
mtd -r write /tmp/openwrt-ramips-mt76x8-xiaomi_miwifi-3c-squashfs-sysupgrade.bin OS1
```

Limitations: For the first install the image size needs to be less
than 7733248 bits.

Specs (same as in v1):
- MT7628AN (575 MHz)
- 64MB RAM
- 8MB of flash (SPI NOR)
- 1x 10/100Mbps Ethernet (MT7628AN built-in switch with vlan)
- 1x 2.4GHz wifi (MT7628AN)
- 1x 5Ghz wifi (MT7612E)
- 4x LEDs (5 GPIO-controlled)
- 1x reset button
- 1x WPS button

The only and important difference between v1 & v3 is in flash memory
layout, so pls don't interchange these 2 builds!

Installation through web-ui (on OEM factory firmware):
1. Visit http://tplinkrepeater.net or the configured IP address of
   your RE305 v3 (default 192.168.0.254).
2. Log in with the password you've set during initial setup of the
   RE305 (there is no default password).
3. Go to Settings -> System Tools -> Firmware upgrade
4. Click Browse and select the OpenWRT image with factory.bin suffix
   (not sysupgrade.bin)
5. A window with a progress bar will appear. Wait until it completes.
6. The RE305 will reboot into OpenWRT and serve DHCP requests on the
   ethernet port.
7. Connect an RJ45 cable from the RE305 to your computer and access
   LuCI at http://192.168.1.1/

 to configure (or use ssh).

Disassembly:
Just unscrew 4 screws in the corners & take off the back cover.
Serial is exposed to the right side of the main board (in the middle)
and marked with TX/RX/3V3/GND, but the holes are filled with solder.

Installation through serial:
1. connect trough serial (1n8, baudrate=57600)
2. setup the TFTP server and connect it via ethernet
   (ipaddr=192.168.0.254 of device, serverip=192.168.0.184 - your pc)
3. boot from a initramfs image first (choose 1 in the bootloader
   options)
4. test it a bit with that, then proceed to run sysupgrade build

MAC addresses as verified by OEM firmware:

  use  OpenWrt  address  reference
  LAN  eth0     *:d2     label
  2g   wlan0    *:d1     label - 1
  5g   wlan1    *:d0     label - 2

  The label MAC address can be found in config 0x2008.

Hardware
--------
MediaTek MT7621AT
16M SPI-NOR Macronix MX25L12835FMI
Microchip PD69104B1 4-Channel PoE-PSE controller
TI TPS2373 PoE-PD controller

PoE-Controller
--------------

By default, the PoE outputs do not work with OpenWrt. To make them output
power, install the "poemgr" package from the packages feed.
This package can control the PD69104B1 PSE controller.

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

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

2. Add the uboot-envtools configuration file /etc/fw_env.config with the
   following content

   $ echo "/dev/mtd1 0x0 0x1000 0x10000 1" > /etc/fw_env.config

3. Update the bootloader environment.

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

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

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

   $ cat /proc/mtd

6. Set the bootselect flag to boot from kernel0

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

7. 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

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

Restore to UniFi
----------------

To restore the vendor firmware, follow the Ubiquiti UniFi TFTP
recovery guide for access points. The process is the same for
the Flex switch.

  - uImage magic ( 0x0 - 0x3 ) : 0x434F4D42 ("COMB")
  - header crc32 ( 0x4 - 0x7 ) : with "data length" and "data crc32"
  - image name   (0x20 - 0x37) : model ID and firmware versions
  - data length  (0x38 - 0x3b) : kernel + rootfs
  - data crc32   (0x3c - 0x3f) : kernel + rootfs

- There are 2x important flags in the flash:

  - bootnum   : select os partition for booting (persist, 0x4)

    - 0x01: firmware
    - 0x02: firmware_2

  - debugflag : allow interrupt kernel loader, it's named as "Z-LOADER"
    (Factory, 0xFE75)

    - 0x00: disable debug
    - 0x01: enable debug
