This commit adds support for a dual-band AX1800 wall plug manufactured by Shenzhen Century Xinyang Tech Co., Ltd. CPU: Mediatek MT7621A (2 cores, 4 threads) RAM: 256i MiB DDR3 (Samsung K4B2G1646F-BCNB) ROM: 16 MiB SPI NOR (Winbond W25Q128JVPQ) Wired: one gigabit RJ45 port (with green/yellow non-GPIO LEDs) WiFi: Mediatek MT7905DAN + MT7975DN (DBDC 2x 2T2R) Ant.: four 2 dBi external antennas (two 2.4GHz, two 5 GHz) GPIO: tri-color status LED (GPIO 13, 14, 16); reset button (GPIO 18) Power: 12V 2-pin JST-XH on main PCB 110/220V AC to 12V1A DC on auxiliary PCB UART: 115200 8n1, SMD pads available on the PCB as J4 pinout is [3v3] (Rx) (Tx) (Gnd) MAC: 1C:BF:CE:xx:xx:xx (2.4 GHz, label) 1C:BF:CE:xx:xx:xx + 1 (ethernet [1]) 1C:BF:CE:xx:xx:xx + 2 (5 GHz) Original firmware is LEDE Reboot 17.01-SNAPSHOT (kernel 4.4.198) with a few custom packages and a non-LuCI web interface. Telnet and SSH are enabled, requiring an unknown root password [2]. Root password is also needed to access the router via UART console, but passwordless telnet can be enabled via a trivial web exploit [3] and then the root password can be removed by editing `/etc/shadow`. Installation: First upload `sysupgrade` binary via web interface at `http://192.168.188.1/settings.shtml` and wait until getting back to the home screen (select network to extend). The installation fails since the original firmware uses `swconfig` and recent versions of OpenWrt use DSA. However, the sysupgrade file is uploaded correctly and stored at `/tmp/upgrade.bin`, so it can be written to flash via the web exploit [4] (both `mtd -r write` and `sysupgrade -Fn` work fine). Passwordless telnet/ssh is not needed for installation. Alternatively, use u-boot menu to load image via TFTP. Notes: - Device model in LEDE is "MediaTek MT7621 RFB (802.11ax,SNOR)". - It is sold under several names, among them are Wodesys WD-R1802U, Fenvi F-AX1802U, and EDUP EP-2971; the Wodesys brand was selected since it is referenced in `/etc/banner` and `/etc/hosts`, and the PCB is marked "WD518A V1.0". - Instead of a standard ethernet transformer, the PCB has a few tiny SMD coils. [1] Original firmware sets ethernet MAC to 1C:BF:CE:E7:62:1D based on offset `0x3fff4` in the Factory partition; since this is the same MAC for all units, whereas WiFi MACs stored at offsets 0x6 and 0xc are unique, it was decided to use <label MAC + 1> for ethernet.
