ramips: add support for Wavlink WL-WN531G3 This device is similiar to the Wavlink WL-WN531A3. Hardware -------- SoC: Mediatek MT7620A RAM: 64MB FLASH: 8MB NOR (GigaDevice GD25Q64CS) ETH: - 2x 10/100/1000 Mbps Ethernet (RTL8211F) - 3x 10/100 Mbps Ethernet (integrated in SOC) WIFI: - 2.4GHz: 1x (integrated in SOC) (2x2:2) - 5GHz: 1x MT7612E (2x2:2) - 4 external antennas BTN: - 1x Reset button - 1x Touchlink button - 1x Turbo button - 1x Wps button - 1x ON/OFF switch LEDS: - 1x Red led (system status) - 1x Blue led (system status) - 5x Blue leds (ethernet ports) - 1x Power led - 1x Wifi led UART: - 57600-8-N-1 Everything works correctly. Installation ------------ Flash the initramfs image in the OEM firmware interface When Openwrt boots, flash the sysupgrade image otherwise you won't be able to keep configuration between reboots. In my case the whole device was locked and there was no way to flash the image, except for flashing directly to the flash via an spi-flasher. You need to put the sysupgrade image file at the beginning of 0x60000.
