This patch ports over support for the device from ar71xx.
SOC: AR7370 (Wasp - AR9344 rev2 0001974c)
RAM: Winbond W9725G6KB-25 32MiB
FLASH: Winbond 25Q64FVSIG 8MiB
WLAN: AR9300 Dual-Band 802.11abgn 3x3:3
INPUT: WPS, RESET button. (hardware Power button)
LED: Power, LAN, WiFi, 3 RSSI-Leds (low, medium, high)
Serial: Header Next to the winbond flash chip (labeld JP1)
Pinout is GND - NC - RX - TX - 3V3 (JP1)
The Serial setting is 115200-8-N-1.
Tested and working:
- LEDs
- Buttons
- Ethernet
- Wi-Fi
- Installation via uboot (see wiki)
- OpenWRT sysupgrade
- TFTP boot from ramdisk image
=> tftpboot 81000000 initramfs.bin
=> bootm
For flashing and debricking information see:
<https://openwrt.org/toh/wd/rext>
Users coming from ar71xx can use sysupgrade too. But I highly
advise to no save the old configuration and start from a clean
state.

Note: back in the day, this device required a special 10/100Mbps
vs 1Gbit/s link speed fix: https://patchwork.ozlabs.org/patch/476713/.
But armed with a better understanding (and more importantly: docs), I
think it's possible to do away with the special fixup_rgmii_tx_delay
code and just set the right delay bits in the pll-data.
