[PATCH] Expose active mmc boot partition to scripts

[Reuben Dowle]

This patch allows uboot scripts make choices about where to boot from based on 
the active mmc boot partition. This allows having two copies of kernel, 
filesystems etc, and choosing which to boot from based off the active 
bootloader partition.
