omap3: overo: Allow boot with kernel in UBI rootfs
If regular NAND booting fails to find a valid uImage in the kernel partition in NAND, try to boot using a zImage and dtb found in a UBI volume in the rootfs partition. This is the NAND analog of mmc zImage booting for device-tree based kernels. Signed-off-by: Ash Charles <ashcharles@gmail.com> Signed-off-by: Arun Bharadwaj <arun@gumstix.com>
