Sounds like a sensible cleanup to me. I think at the time I last
worked on the mpcore objects I was mostly interested in pulling
out the common bits (ie mptimer) and didn't worry so much about
the bits that were genuinely core specific. But splitting out
the SCU is really the right way to model it.

Better done sooner than later (ie months, not years), at some point
we're going to have to stop allowing ourselves to break ARM migration
compatibility...
