ath79: add support for 8devices Lima board

Specification:

  • 650/600/216 MHz (CPU/DDR/AHB)
  • 64 MB of RAM (DDR2)
  • 32 MB of FLASH
  • 2T2R 2.4 GHz
  • 2x 10/100 Mbps Ethernet
  • 1x USB 2.0 Host socket
  • 1x miniPCIe slot
  • UART for serial console
  • 14x GPIO

Flash instructions:

Upgrading from ar71xx target:

  • Upload image into the board:
    scp openwrt-ath79-generic-8dev_lima-squashfs-sysupgrade.bin
    root@192.168.1.1/tmp/
  • Run sysupgrade
    sysupgrade -F /tmp/openwrt-ath79-generic-8dev_lima-squashfs-sysupgrade.bin

Upgrading from u-boot:

  • Set up tftp server with
    openwrt-ath79-generic-8dev_lima-initramfs-kernel.bin
  • Go to u-boot (reboot and press ESC when prompted)
  • Set TFTP server IP
    setenv serverip 192.168.1.254
  • Set device ip from the same subnet
    setenv ipaddr 192.168.1.1
  • Copy new firmware to board
    tftpboot 0x82000000 initramfs.bin
  • Boot OpenWRT
    bootm 0x82000000
  • Upload image openwrt-ath79-generic-8dev_lima-squashfs-sysupgrade.bin into
    the board
  • Run sysupgrade.
