[PATCH v2 0/3] Exynos Mobile DFU and blkmap additions

This series has two additions for support for blkmap and capsule updates
via DFU. The blkmap support is due to booting from sub-partitions from the
userdata partition.

The series also has a patch which fixes U-Boot builds from failing due
to the lack of a default fallback device tree.

This must go through u-boot-samsung. Would be nice to get this accepted
in this cycle itself.
