OMAP3: igep00x0: allow booting with a FDT from MMC
IGEP boards now have Device Tree support in the mainline kernel. To boot an IGEP board using a DT, a uEnv.txt plain text file could be used to define a custom uenvcmd that will be run by the default boot command. It is more convenient to change the default boot command to allow loading a FDT if it is stored in the boot dir of the rootfs uSD/MMC partition. If no FDT is found then the defaul command tries to boot a zImage without a DT using legacy boot. Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk>
