It was due to lowlevel_init.S calculating the address of SMRDATA
with the assumption that we're running from RAM. I've not changed
this to PC-relative.

With the change above, we don't need it anymore. In fact, we
could probably remove CONFIG_LL_INIT_NAND_ONLY entirely. Shall we
give this a try now, or wait for more quiet days ?

Well, it took a little longer, but it's now in start.S. I noticed
that we have quite a bit of patch noise now (had me chasing ghosts
for a good while, too), so perhaps a global refresh wouldn't be so
