Okay, that's what I wanted to know. However, I believe your patch to
be incorrect. You delete the assignments to initrd_start and initrd_end
in arm_memblock_init(), which will result in non-OF platforms having
no initrd.
The reason is that OF platforms set initrd_start and initrd_size from
the OF code (drivers/of/fdt.c), but ATAG platforms only set our private
phys_* versions.
The reason I went with phys_* stuff was to permit better verification
of the addresses passed - that the addresses were indeed memory locations
before passing them through something like __va().
