devices, but since this won't cover runtime assigned (hotplugged)
ones, I don't think this would gain you anything.

Well, you described what you do (with quite a bit of ARM terminology
I don't understand), but I'm not sure you made explicit what problem(s)
you need to solve. I'm sorry if it's just me not understanding what you
wrote.
