Reviewing / accepting this patch is up to the u-boot maintainers, not
me. I just provided this patch as I think it could be useful.

This is because mkimage is generic tool which supports all image formats

different ARM images, not only x86. I guess this is primary intended for
Linux distributions to support all U-Boot targets...
