ramips: add support for YunCore AX820/HWAP-AX820
There are two versions which are identical apart from the enclosure: YunCore AX820: indoor ceiling mount AP with integrated antennas YunCore HWAP-AX820: outdoor enclosure with external (N) connectors Hardware specs: SoC: MediaTek MT7621DAT Flash: 16 MiB SPI NOR RAM: 128MiB (DDR3, integrated) WiFi: MT7905DAN+MT7975DN 2.4/5GHz 2T2R 802.11ax Ethernet: 10/100/1000 Mbps x2 (WAN/PoE+LAN) LED: Status (green) Button: Reset Power: 802.11af/at PoE; DC 12V,1A Antennas: AX820(indoor): 4dBi internal; HWAP-AX820(outdoor): external Flash instructions: The "OpenWRT support" version of the AX820 comes with a LEDE-based firmware with proprietary MTK drivers and a luci webinterface and ssh accessible under 192.168.1.1 on LAN; user root, no password. The sysupgrade.bin can be flashed using luci or sysupgrade via ssh, you will have to force the upgrade due to a different factory name. Remember: Do *not* preserve factory configuration! MAC addresses as used by OEM firmware: use address source 2g 44:D1:FA:*:0b Factory 0x0004 (label) 5g 46:D1:FA:*:0b LAA of 2g lan 44:D1:FA:*:0c Factory 0xe000 wan 44:D1:FA:*:0d Factory 0xe000 + 1 The wan MAC can also be found in 0xe006 but is not used by OEM dtb. Due to different MAC handling in mt76 the LAA derived from lan is used for 2g to prevent duplicate MACs when creating multiple interfaces. Signed-off-by: Clemens Hopfer <openwrt@wireloss.net>
