The uImage format is causing some trouble on ARM because it requires knowing
the load address at boot time, so we try to move people towards using just
zImage files there. You might want to consider the same.

It's probably not necessary to have both lzma and xz formats since they
are the same algorithm with different headers afaik.

The header files will have to change now for the UAPI split, see the discussion
about the same thing for the ARC architecture.
