Subject: [PATCH] ath79: add support for Mikrotik LHG 5
The MikroTik LHG 5 series (product codes RBLHG-5nD, RBLHG-5HPnD and
RBLHG-5HPnD-XL) devices are an outdoor 5GHz CPE with a 24.5dBi or 27dBi
integrated antenna built around the Atheros AR9344 SoC.
It is very similar to the SXT Lite5 series which this patch is based
upon.
Specifications:
- SoC: Atheros AR9344
- RAM: 64 MB
- Storage: 16 MB SPI NOR
- Wireless: Atheros AR9340 (SoC) 802.11a/n 2x2:2
- Ethernet: Atheros AR8229 switch (SoC), 1x 10/100 port,
8-32 Vdc PoE in
- 8 user-controllable LEDs:
- 1x power (blue)
- 1x user (white)
- 1x ethernet (green)
- 5x rssi (green)
See https://mikrotik.com/product/RBLHG-5nD for more details.
Notes:
The device was already supported in the ar71xx target.
Flashing:
TFTP boot initramfs image and then perform a sysupgrade. Follow common
MikroTik procedure as in https://openwrt.org/toh/mikrotik/common.
