So far it looks like any arm board... I was working on specifically
the imx6 quad core wandboard bringup. But i've also verified it on
the Panda/Beagle too... Alll 3 of these boards worked fine with
v2013.07-rc1...

Wandboard:

Boot Sequence: (device tree boot)
load mmc ${mmcdev}:${mmcpart} ${loadaddr} zImage
load mmc ${mmcdev}:${mmcpart} ${fdt_addr} /dtbs/${fdt_file}
bootz ${loadaddr} - ${fdt_addr}
