I have a fundamental question:

If I have to port LINUX on to new processor. How will I get address
mapping of different devices. Some of them are available in the manual.
Ex: NVram starting address is not available.
Iam porting on mips3k.

It may sound very dumb, but Iam stuck there.

Thanks

I would recommend looking at the list at [email protected]. I am
fairly sure there is an R3k port already being worked on. I assume the
mips3k processor you refer to is the R3k (which is very similar to the
R2k)?

Related question: does there exist any kind of definition of the abstract interface between the architecture-independent and architecture-dependent parts of the kernel? Or am I being naive?

In this case you have to contact the hardware vendor for specifications,
but at least in my experience, not many vendors are willing to part with
this information
