Nit: I think this should be HasMips3D.

This should include the HasMips3D predicate so that the CompleteModel check passes..

This addition looks incorrect. Looking at the MIPS32® P5600 Multiprocessing System Software User’s Manual, Revision 01.60, on page 646, it says that wired paired single is not available on the P5600.

Thanks for the catching the issues.
