MikroTik RouterBoard RB711-5Hn-MMCX
The device is not yet supported but there is some code ready to test in trunk. So far (February 2015), wifi modules crash with a kernel panic, ethernet does not transmit any packages successfully and and the flash layout doesn't look right.

Installation
If you flash OpenWrt from NetBoot facility, you will lose your RouterOS licence.
If you build OpenWrt from trunk, you first have to apply a patch:
wget "https://onny.project-insanity.org/files/rb711-openwrt.patch" patch -p0 < rb711-openwrt.patch make defconfig
Then select these menuconfig options:
Target System: Atheros AR71xx Subtarget: Mikrotik devices with NAND flash Target Images: ramdisk
You have to adjust following config parameters in this file: target/linux/ar71xx/mikrotik/config-default before compiling
CONFIG_CMDLINE="console=ttyS0,115200 GPIO_RESET=yes gpio=790341 HZ=200000000 mem=32M board=711 boot=0 mlc=2 rootfstype=yaffs noinitrd" CONFIG_CMDLINE_OVERRIDE=y
Here's an easy way to setup Dhcp and Tftp using Dnsmasq:
sudo service network-manager stop sudo ifconfig eth1 192.168.1.2 up sudo dnsmasq -i eth1 --dhcp-range=192.168.1.100,192.168.1.200 --dhcp-boot=openwrt-ar71xx-nand-vmlinux-initramfs.elf --enable-tftp --tftp-root=/tmp/openwrt -d -p0 -K --log-dhcp --bootp-dynamic
Connect ethernet to your RouterBoard device and holt the S301 button pressed while booting it up. LED LD301 starts lighting up, then flashing and than turns off. After this you can release the button and the router starts looking for a TFTP server providing an elf-image. If you want to have a look at the booting process, you can solder RS232 serial connection to your board (see picture below) and connect to it for example with this command:
sudo minicom -D /dev/ttyUSB0 -b 115200
Important to note: Serial output is disabled by default by the bootloader. Therefore, the first output comes with your OpenWrt kernel booting. Here's my bootup log (an older one!, dmesg):
