The changelog needs to go below the '---' so that git will drop it when
applyng.

This should be %zu not %lu.

There is no decompress_data function. And I suspect what you should do
here is the switch logic from common/bootm.c::bootm_decomp_image()
without the print (so re-factor that function a bit more).
Finally, you're adding some whitespace issues (empty lines with just
spaces), please run checkpatch.pl against it before submission next
time. Thanks!
