Is it going to be (or very likely to be) the case that a given AXPxxx
device will only ever be a primary or a secondary,  but never used as both
(perhaps on different boards)?

Is there some property of these devices which causes them to be only usable
as one or the other?

If there is some possibility of this not being the case then this
unification + my comments on patch #1 might be seen in a different light.

Having a board which uses two of the same AXPxxx device looks like it would
be even more problematic, if such a thing is possible.

Or is the plan to just cross that bridge if/when we get there? (I think I'm
 OK with that).

Ian.
