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.

closes freifunk-gluon/gluon#2603

Co-authored-by: Martin Weinelt <martin@darmstadt.freifunk.net>

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)

To install via EVA bootloader, a FTP connection need to be
established to 192.168.178.1 within the first seconds after power on:

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

Since sphinx-5.0.0 "None" is not recommended anymore.

The DTS model name has been changed to "TP-Link Archer C6 v2 (EU/RU/JP)"
to distinguish it from the US version.

Was commented out in the former commit.

Removed in 45c84a11 ("ar71xx: drop target").

Re-add mikrotik target

Note that previous images were generic ones and as such no migration
path is provided other than manually flashing the image via config-mode.
