More walnut boottime "fun"

	Hi,

	Apart from NFS not working, it looks like the bootloader is
clobbering itself when the image is reasonably large (> 1M?).

	This happens when it relocates itself (the initrd or whatever
overwrites the relocation code).

	Has anyone fixed this, or should I keep going ;)

	Simon

p.s. this is only an issue where the dest address < the load address, as
on walnut and friends

There's certain dead-zones now.  Check out
arch/ppc/boot/common/relocate.S for the constraints.  Tomorrow I plan on
implementing a slightly smarter relocate that moves the text, jumps
there and then relocates data, which should bring us back to the same
size deadzones that the original code had.
