Hopefully, I'll be able to get zImages working on MSM8x60 today, and I
can test this.  I think the above might need some work to handle
multiple ATAG_MEM attributes (our memory isn't contiguous).  I can look
at this once I get it working.

Does this mean that merging appended DTB and atags requires using a
compressed kernel?  It seems that several years ago, someone tested the
decompressor on a slow MSM and decided to boot from the uncompressed
image, and nobody has bothered with the compressed image.  I don't think
it is a problem to require zImage for this case, though.
