OK, why?  I could be entirely wrong here but I had thought for some
reason that if the ramdisk was in "highmem" the kernel would relocate
contents (or if compressed, uncompress to a non-highmem location).  The
FDT must be in lowmem as that tells the kernel where memory even is.  Is
this not the case?  Thanks!
