027b728d4a Add support for LZ4 decompression algorithm
This patch adds support for LZ4-compressed FIT image contents. This
algorithm has a slightly worse compression ration than LZO while being
nearly twice as fast to decompress. When loading images from a fast
storage medium this usually results in a boot time win.

Sandbox-tested only since I don't have a U-Boot development system set
up right now. The code was imported unchanged from coreboot where it's
proven to work, though. I'm mostly interested in getting this recognized
by mkImage for use in a downstream project.

0eb25b6196 common: Make sure arch-specific map_sysmem() is defined
In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.

Also split the non-arch specific functions out of common.h

6ed4dc7876 test: Add unit tests for bootm image decompression
Use each compression method (including uncompressed). Test for normal
operation, insufficient space and corrupted data.

3153e915b4 sandbox: add compression tests
This adds the "test_compression" command when building the sandbox. This
tests the existing compression and decompression routines for simple
sanity and for buffer overflow conditions.
