I get terribly confused with the differences in the various MIPS CPU 
models so please bear with me.

Are the CPU models used by the p4000/p4600/p4650 BSP MIPS32 ones?  I
thought they were the Orion's which are some older 64-bit embedded
MIPS variant.  Is this what became known as MIPS32?

I am prone to say yes .. a functional MIPS32 BSP is better than
an Orion BSP no one has hardware for as long as they cover the same
class of CPUs.  Some BSPs are for custom hardware and only serve
as examples/starting points for new BSPs.

So if you have a functioning MIPS32 BSP and I asked you to write
one for the ITD 4650, would it be of any use?
