ath79: Add support for OpenMesh MR600 v2
Device specifications: ====================== * Qualcomm/Atheros AR9344 rev 2 * 560/450/225 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 * 2T2R 5 GHz Wi-Fi * 8x GPIO-LEDs (6x wifi, 1x wps, 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) * 1x ethernet - AR8035 ethernet PHY (RGMII) - 10/100/1000 Mbps Ethernet - 802.3af POE - used as LAN interface * 12-24V 1A DC * internal antennas 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@192.168.1.1:/tmp/ On the device, the sysupgrade must then be started using sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin Signed-off-by: Sven Eckelmann <sven@narfation.org> [rebase, add LED migration] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
