I intend to look at this. I'm fighting a nasty cold right now so I'm doing so
moving very fast.

I agree to some extent. Having a default chipset implementation of
a fallack mechanism could be useful. In the general case you need to
be per board. But there is no reason not to provide helper functions.
At least with the code in C. Someone can modify the code and
have a reasonable chance of it working on ports they cannot test.

The vision is to get enough pieces into a general framework so we can
freeze the APIs or at least put them in serious slush mode. Getting
nearly everything into the device tree as we have looks like a significant
step in that direction.
The big remaining piece is to figure out how to get irq routing into a generic
framework. Right now we have some functional hacks but code reuse is hard.
