This device is already supported.
It's a lantiq device that was entered as ar71xx
in to the list of supported device and therefore
removed before the release of Gluon 22.

(cherry picked from commit 95e5d382)

(cherry picked from commit 33fa77a7)

(cherry picked from commit 267124b5)

Upstream added a standalone SPI kernel-loader which fixes the unbootable
image for the WDR4900. Thus, we can re-introduce this device to Gluon.

Specification:

SoC: MediaTek MT7628AN
RAM: 64MiB
Flash: 8MiB
Wifi:
  - 2.4GHz: MT7628AN
  - 5GHz: MT7612EN
LAN: 1x 10/100 Mbps

Flash instructions:
Flash factory image through stock firmware WEB UI.
Back to stock is possible by using TFTP and stripping down the Firmware
provided by TP-Link to a initramfs.

The flash space between 0x650000 and 0x7f0000
is blank in the stock firmware so I left it out as well.

Note: Buffalo has introduced hardware changes without bumping the
revision number. 19.07 did not support the rb-variant so there's no need
to implement a migration for the rb-variant.
Every g300nh supported by Gluon should either be the s-variant or
been flashed wrongly.

Note that it was wrongly marked as device class tiny in
commit 7fd7116e ("targets: add device-class flags") in the past,
the device has 64MB RAM and not 32MB.

Also, the device has no "led-running" assigned in DTS. The device has
three LEDs: "green:vpn", "green:lan" and "green:wlan". The first LED,
"green:vpn", has a "V" icon and was used to show the VPN connection
status in the vendor firmware. This LED will be used via the newly
added "led-boot" fallback in gluon-setup-mode. But will be unused
during normal operation due to the unassigned "led-running" in DTS.

The CN/RU variant of the device has the same hardware
as the EU already supported, but contains a 16M flash chip.

Gone due to
commit 45c84a11 ("ar71xx: drop target")

ar71xx only supported the 8M variant

Specifications:
* SoC: AR7242 (Virian 400MHz)
* RAM: 64 MB DDR (W9751G6JB-25)
* Flash: 16MB SPI flash (S25FL129PIF)
* WiFi: AR9382 (2.4/5GHz) + 2x SE2595L
* LAN: 1x1000M (PEF7071V)

Both are effectively the same hardware, the latter being Buffalos
replacement model.
