I looked at the contents here, and I'm not too fond of adding
low-level register access interfaces to firmware drivers,
that is usually a bad idea because it ties the interface
to a particular platform.

I have no idea what 'CSU registers' are and the ABI
description does not really explain that either.

What type of userspace would access those, and why can't
this be done in a portable way?

No objections here, though they look like bugfixes that
may be 7.1 material. Up to you, but don't be shy about
sending things as bugfixes when they address real
problems, it's better than waiting for the merge window
and then immediately asking for a backport.
