ramips: add Edimax EW-7476RPC
SoC: MediaTek MT7620a @ 580MHz
RAM: 64M (Winbond W9751G6KB-25)
FLASH: 8MB (Macronix)
WiFi: SoC-integrated: MediaTek MT7620a bgn
WiFi: MediaTek MT7612EN nac
GbE: 1x (RTL8211E)
BTN: WPS - RFKILL/RF 50%/RF 100% toggle
LED: - Wifi 5g (blue)
- Wifi 2g (blue)
- Crossband (green)
- Power (green)
- WPS (green)
- LAN (Green)
UART: UART is present as Pads with throughholes on the PCB. They are
located next to the switch for the wifi configuration
3.3V - RX - GND - TX / 57600-8N1
3.3V is the square pad
Installation
------------
Update the factory image via the web-interfaces (by default:
192.168.9.2/24).

3.3V - RX - GND - TX / 57600-8N1
3.3V is the square pad
Installation
------------
Update the factory image via the web-interfaces (by default:
http://edimaxext.setup)
Or push wpa button on power on and send firmware via tftp to 192.168.1.6
The EW-7478AC is identical to the EW-7476RPC, except instead of 2 internal
antennas it has 2 external ones.
