Its an NEC 5074 development board with an VR5000 --
32K I and 32K D Primary cache
no secondary cache.
which vec0 code should I be using?
NEC seems to have a bunch of errata and hazards in this part when
dealing with TLBWR and friends... Is any of the existing code supposed
to respect these?
Also, arch/mips/Makefile makes the compiler use -r8000 -mips2, is
that right?
