ramips: add support for TP-Link Archer C20 v4
TP-Link Archer C20 v4 is a router with 5-port FE switch and non-detachable antennas. It's based on MediaTek MT7628N+MT7610EN. Specification: - MediaTek MT7628N/N (580 Mhz) - 64 MB of RAM - 8 MB of FLASH - 2T2R 2.4 GHz and 1T1R 5 GHz - 5x 10/100 Mbps Ethernet - 3x external, non-detachable antennas - UART (J1) header on PCB (115200 8n1) - 7x LED (GPIO-controlled*), 2x button, power input switch * WAN LED in this devices is a dual-color, dual-leads type which isn't (fully) supported by gpio-leds driver. This type of LED requires both GPIOs state change at the same time to select color or turn it off. For now, we support/use only the green part of the LED. * MT7610EN ac chip isn't not supported by LEDE. Therefore 5Ghz won't work. Flash instruction: The only way to flash LEDE image in ArcherC20v4 is to use tftp recovery mode in U-Boot: 1. Configure PC with static IP 192.168.0.66/24 and tftp server. 2. Rename "openwrt-ramips-mt7628-ArcherC20v4-squashfs-tftp-recovery.bin" to "tp_recovery.bin" and place it in tftp server directory. 3. Connect PC with one of LAN ports, press the reset button, power up the router and keep button pressed for around 6-7 seconds, until device starts downloading the file. 4. Router will download file from server, write it to flash and reboot. Signed-off-by: Maxim Anisimov <maxim.anisimov.ua@gmail.com>
