    ath79: add support for ASUS RT-AC59U / ZenWiFi CD6
    
    ASUS RT-AC59U / RT-AC59U v2 are wi-fi routers with a large number of
    alternate names, including RT-AC1200GE, RT-AC1300G PLUS, RT-AC1500UHP,
    RT-AC57U v2/v3, RT-AC58U v2/v3, and RT-ACRH12.
    
    ASUS ZenWiFi AC Mini(CD6) is a mesh wifi system. The unit labeled CD6R
    is the router, and CD6N is the node.
    
    Hardware:
    
    - SoC: QCN5502
    - RAM: 128 MiB
    - UART: 115200 baud (labeled on boards)
    - Wireless:
      - 2.4GHz: QCN5502 on-chip 4x4 802.11b/g/n
        currently unsupported due to missing support for QCN550x in ath9k
      - 5GHz: QCA9888 pcie 5GHz 2x2 802.11a/n/ac
    - Flash: SPI NOR
      - RT-AC59U / CD6N: 16 MiB
      - RT-AC59U v2 / CD6R: 32 MiB
    - Ethernet: gigabit
      - RT-AC59U / RT-AC59U v2: 4x LAN 1x WAN
      - CD6R: 3x LAN 1x WAN
      - CD6N: 2x LAN
    - USB:
      - RT-AC59U / RT-AC59U v2: 1 port USB 2.0
      - CD6R / CD6N: none
    
    WiFi calibration data contains valid MAC addresses.
    
    The initramfs image is uncompressed because I was unable to boot a
    compressed initramfs from memory (gzip or lzma). Booting a compressed
    image from flash works fine.
    
    Installation:
    
    To install without opening the case:
    
    - Set your computer IP address to 192.168.1.10/24
    - Power up with the Reset button pressed
    - Release the Reset button after about 5 seconds or until you see the
      power LED blinking slowly
    - Upload OpenWRT factory image via TFTP client to 192.168.1.1
    
    Revert to stock firmware using the same TFTP method.
