Applied, thanks.  However...

This change means that if someone builds another board with the same CPU
on it then they'll have to add all the objects for the core CPU support
to the Makefile entry for their board.  There should at least be a
separate Kconfig thing, even if it's not user visible.  I've committed a
patch backing this bit out for now.

This probably shouldn't be on by default?

In general, it'd be a bit easier to review the changes you're making if
you were able to submit individual changes in separate patches, though I
appreciate that at the minute you're making a lot of changes that go
over large portions of the code and can't be easily separated out so I
wouldn't worry about it too much.
