To boot Linux, we should prevent Initramdisk and FDT from going too high.

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!
