That one was interesting - the bcsr was being referenced from an
ethernet driver that looked to me like it would be useful on any board
based on an 836x chip (I think).  Yet it was claimed that the bcsr was
so specific and unique to each board that there was no point putting
it in the device tree - which implies that we would have to have a
separate lump of code in the tree to drive it for every single
board. :P  I asked why the ethernet driver was accessing it directly
if that was the case, but didn't get an answer (well, only an indirect
answer in that the bcsr access code got removed from the ethernet
driver).
