    ramips: add support for HiLink HLK-7621A evaluation board
    
    Specifications:
    - SoC: MediaTek MT7621AT
    - RAM: 256 MB (DDR3)
    - Flash: 32 MB SPI NOR 44MHz
    - Switch: 1 WAN, 4 LAN (Gigabit)
    - LEDs: 1 WAN, 4 LAN (controlled by PHY)
    - USB Ports: 1 x USB2, 1 x USB3
    - WLAN: 1 x 2.4, 5 GHz 866Mbps (MT7612E)
    - Button: 1 button (reset)
    - UART Serial: UART1 as console : 57600 baud
    - Power: 12VDC, 1A
    
    Installation:
    Update openWRT firmware using internal GNUBEE uboot:
    https://github.com/gnubee-git/GnuBee-MT7621-uboot
    
    By HTTP: Initial uboot address is http://10.10.10.123, your address
    needs to be 10.10.10.x, and mask 255.255.255.0.
    By TFTP: Uboot is in client mode, the address of the firmware must
    be tftp://10.10.10.3/uboot.bin
    
    Recovery:
    Manufacturer provides MTK OpenWrt 14.07 source code, compile then
    flash it by uboot.
    HLK-7621A is a stamp hole package module for embedded development,
    users have to design IO boards to use it.
    
    MAC addresses:
    - u-boot-env contains a placeholder address:
      > mtd_get_mac_ascii u-boot-env ethaddr
      03:17:73:ab:cd:ef
    - phy0 gets a valid-looking address:
      > cat /sys/class/ieee80211/phy0/macaddress
      f8:62:aa:**:**:a8
    - Calibration data for &pcie2 contains a valid address, however the
      zeros in the right half look like it's not real:
      8c:88:2b:00:00:1b
    - Since it's an evaluation board and there is no solid information
      about the MAC address assignment, the ethernet MAC address is left random.
