In addition, I moved the vmlinux elf header decompress code from
prep_kernel() to its own routine and called it before platform_init.
I then pass the elf header ptr into platform_init.  That way,
platform_init can figure out where the end of the kernel will
be and put the dtb beyond it.  The OF code can now change
claim_base in platform_init instead of needing the platform_ops.image_hdr
hook.

Hmmm.  What if platform_init needs to e.g. turn on caches or do other
things that need to be done before decompressing?  I think it's
important to provide some way for the platform code to do things
really early on.

Good point.  I'll make a separate hook so it'll be platform_init, then
get_elfheader, then call new hook, then open console & do the rest.
