    ath79: Add support for OpenMesh OM5P-AC v2
    
    Device specifications:
    ======================
    
    * Qualcomm/Atheros QCA9558 ver 1 rev 0
    * 720/600/200 MHz (CPU/DDR/AHB)
    * 128 MB of RAM
    * 16 MB of SPI NOR flash
      - 2x 7 MB available; but one of the 7 MB regions is the recovery image
    * 2T2R 2.4 GHz Wi-Fi (11n)
    * 2T2R 5 GHz Wi-Fi (11ac)
    * 4x GPIO-LEDs (3x wifi, 1x power)
    * 1x GPIO-button (reset)
    * external h/w watchdog (enabled by default))
    * TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX)
    * TI tmp423 (package kmod-hwmon-tmp421) for temperature monitoring
    * 2x ethernet
      - eth0
        + AR8035 ethernet PHY (RGMII)
        + 10/100/1000 Mbps Ethernet
        + 802.3af POE
        + used as LAN interface
      - eth1
        + AR8031 ethernet PHY (RGMII)
        + 10/100/1000 Mbps Ethernet
        + 18-24V passive POE (mode B)
        + used as WAN interface
    * 12-24V 1A DC
    * internal antennas
    
    This device support is based on the partially working stub from commit
    53c474abbdfe ("ath79: add new OF only target for QCA MIPS silicon").
    
    Flashing instructions:
    ======================
    
    Various methods can be used to install the actual image on the flash.
    Two easy ones are:
    
    ap51-flash
    ----------
    
    The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
    used to transfer the image to the u-boot when the device boots up.
    
    initramfs from TFTP
    -------------------
    
    The serial console must be used to access the u-boot shell during bootup.
    It can then be used to first boot up the initramfs image from a TFTP server
    (here with the IP 192.168.1.21):
    
       setenv serverip 192.168.1.21
       setenv ipaddr 192.168.1.1
       tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr
    
    The actual sysupgrade image can then be transferred (on the LAN port) to the
    device via
    
      scp <filename-of-squashfs-sysupgrade>.bin root at 192.168.1.1:/tmp/
    
    On the device, the sysupgrade must then be started using
    
      sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin
