Right, that doesn't mean this is a great way of doing things, though -
it's been a frequent source of errors in the past and is painful to
debug as the data structures get rewritten during boot which is a bit of
a surprise.

Yes, that's the normal way of handling this and is actually what the
code was originally doing - there's a bunch of ifdefed devices in
plat-samsung/devs.c.  You usually have to do this anyway as the IPs move
about so the resources need changing.
