ramips: add support for Fon FON2601
FON2601 is a wireless router. Specification: - SoC: Mediatek MT7620A (580MHz) - RAM: 128 MiB - ROM: 16 MiB SPI Flash - Wireless: for 11b/g/n (upto 300 Mbps): MT7620A built-in WMAC for 11a/n/ac (upto 867 Mbps): MT7662E - Ethernet LAN: 1 port, upto 100 Mbps - Ethernet WAN: 1 port, upto 1000 Mbps - USB: 1 port (USB 2.0 host) - LEDs: 4 (all can be controlled by SoC's GPIO) - buttons: 1 (Displayed as "WPS" on enclosure) - serial port: 57600n8 pins: Vcc(3.3V), Rx, Tx, GND (left to right, viewed from outside of board) Installation (only available via UART): 1. download sysupgrade binary image by wget command 2. write sysupgrade binary image to Flash command is: mtd write sysupgrade.bin firmware 3. reboot Important Notice: Only one button is displayed as "WPS" on enclosure. However, it is configured as "reset" (factory resetting feature).
