Hmm. I thought ST-Erricson folks had something similar.
Anyway, maybe we've been going about this the wrong way. Couldn't we
just make TEXT_OFFSET be 0x00208000 and then make sure to remove the
first 2MB of memory in a machine->reserve() routine if we're MSM?
Something like PHYS_OFFSET=0xN0000000 and TEXT_OFFSET=0x00208000 so that
our text ends up at the right place (0xN0208000) and AUTO_ZRELADDR will
be happy. This seems to work as long as I fixup the atags to say memory
starts at 0xN000000 instead of 0xN0200000.
