ARM: IGEP0033: Add support to boot from NAND.
Add to the default environment the possibily to boot from NAND using a ubi rootfs. Also the partition scheme is set as follows: Start Size SPL : 0x00000000 0x00080000 (512KiB) U-Boot : 0x00080000 0x00100000 (1MiB) U-Boot Env : 0x00180000 0x00020000 (128KiB) File System : 0x001C0000 - The ubiboot script gets the kernel and the dtb file from the boot directory of the File System.
