This is one way to fix these build errors. Is that what the MIPS people
want to do or should their be APIs to access these base addresses and
mips_cm_is64 data?
A similar patch was already sent a few weeks ago and Thomas asked for
a different approach [0].
I have sent a patch series removing mips stuff from the driver
controller. This series has not been reviewed yet [1].

Oh, very good then. Thanks.
