Just getting back to things after the break...

We are looking at modeling some microcontrollers on the POWER
chips. There is an OCC power management controller which is a 405
and some other weird cut down 405 derivatives, we're not up to
those yet but we want to model them.

We should be able to remove a bunch of boards and CPUs, I just
haven't started looking, so might be easier to wait for a bit.
If it's not causing others too much problem, could we leave this
in for the time being?

Thanks,
Nick
