I discussed with Alex and Alice that it would be good to land the register!=
()
macro this cycle (having some local to register.rs bitfield support), so dr=
ivers
can start using it next cycle.

Subsequently, we can follow up on the discussions for global bitfield suppo=
rt.

For this purpose, it would be nice if I could pick up those two prerequisit=
es as
part of this.
