Do you have the new interface in the cortex port branches? If it
implements it the old way, we can merge it in trunk then merge it in
ugpio.
No need to keep all branches really up to date.

Since this could break some platforms, I thought it would be best to
stage it in a branch first.

It isn't too much work to simply satisfy the specs. It can be
optimized on each platform later after the merge, as long as the
public interface doesn't change.
