ramips: mt76x8: Add support for Zbtlink ZBT-WE2426-B

The Zbtlink ZBT-WE2426-B is an indoor dual band WiFi router with 4 external non detachable antennas and 5 Fast Ethernet ports. Hardware of ZBT-WE2426-B: - SoC: MT7628AN - RAM: 64 MB (Winbond W9751G6K8-25) - Storage: 8 MB SPI flash (S25FL064K) - Ethernet: 5x 10/100 Mbps LAN1,LAN2,LAN3,LAN4 & WAN - Wireless: 2.4GHz: on SoC (802.11b/g/n) - Wireless: 5GHz: Mediatek MT7612EN (802.11n/ac) - LEDs: 8x - Buttons: 1x reset - USB: 1x 2.0 - MicroSD slot: 1x - Power: 9 VDC, 1 A - Uart: GND TX RX PWR - J1 on the PCB - Board silkscreen: "ZBT-WE2426-C V04" "2018-02-28" "CTT" "13 18" Backup the stock firmware, settings and calibration data: This router comes with PandoraBox OpenWrt firmware, so it is possible to get all MTD partitions using scp. Installation: - Using the bootloader web server. Hold the reset button while turning the power on. Upload the sysupgrade image on http://192.168.1.1. - Using the sysupgrade command in PandoraBox OpenWrt. LEDs: - LAN1,LAN2,LAN3,LAN4,WAN,WLAN2G use GPIO pins of the MT7628AN SoC (GPIOs 43,42,41,40,39,44) - WLAN5G uses pin of MT7612EN. - The POWER LED is directly connected to the VCC. It can be reconnected to the GPIO 37 of the MT7628AN SoC by resoldering SMD resistor on the PCB. Buttons: - The RESET button is connected to the GPIO 38 of the MT7628AN SoC. MAC addresses as verified by OEM firmware: use address source 2g *:b0 factory 0x4 (label) 5g *:b1 factory 0x8004 LAN *:b2 factory 0x28 WAN *:b3 factory 0x2e Signed-off-by: Vaclav Svoboda <[email protected]> Link: openwrt/openwrt#16927 Signed-off-by: Hauke Mehrtens <[email protected]>
