To: u-boot
A new 'update_emmc_firmware' target is added to allow for easy U-Boot
update in the eMMC as it has secury boot partition and this needs
specific handling on how to program the specific partition.

The zImage works for FSL Linux's kernel fork versions 3.0.35, 3.10.9, and 3.10.17; this also works fine for mainline kernels.
