At the end of the line, some kind of hardware glue is going to be needed.

I just feel that drawing from a sample size of 1 (maybe 2 if I get to throw
in the beagleboard), it is a bit premature to think about making it overly
general, besides the part that are obviously part of the infrastructure
(like the DT overlay stuff).

What I'm getting at, is that we need some user experience about this, before
going away and creating structure out of possible misconception about the uses.
