    ar71xx: add support for YunCore T830
    
    YunCore T830 is a simple N300 router with 5-port FE switch, detachable
    antennas and USB 2.0 port.
    
    Specification:
    
    - 650/597/216 MHz (CPU/DDR/AHB)
    - 128 MB of RAM (DDR2)
    - 16 MB of FLASH (SPI NOR)
    - 5x 10/100 Mbps Ethernet
    - 2T2R 2.4 GHz (QCA9531), with ext. PA (SKY65174-21) and LNA
    - two external, detachable antennas (RP-SMA)
    - 1x USB 2.0
    - 8x LED (7 driven by GPIO)
    - 1x button (reset)
    - DC jack for main power input (12 V)
    - UART and JTAG headers on PCB
    
    Flash instruction:
    
    1. First, gain root access to the device, following below steps:
    
    - Login into web gui (default password/IP: admin/192.168.188.253).
    - Go to "Advanced" -> "Management" -> "System" and download backup of
      configuration (bakfile.bin).
    - Open the file as tar.gz archive, edit/update "shadow" file and change
      hash of root password to something known.
    - Repack the archive, rename it back to "bakfile.bin" and use to
      restore configuration of the device.
    - After that, device will reboot and can be accessed over SSH.
    
    2. Then, install OpenWrt:
    
    - Login over SSH and issue command:
      fw_setenv bootcmd "bootm 0x9f050000 || bootm 0x9fe80000"
    - Upload "sysupgrade" image and install it (only if previous command
      succeeded) with command: "sysupgrade -n -F openwrt-...".
