This seems sane to me assuming that alchemy, sibyte, sandcraft, nxp, and
broadcom all have standard mips{32,64} watch registers (i.e., if the
watch bit in config1 is set the registers have mips semantics).
The watch bit is a standard feature of the MIPS R1/R2 architecture. What
Sandcraft did was bascially an RM7000 clone with some extensions. I'm
still trying to track somebody who could verify the correctness of that
code as I don't have Sandcraft docs ...
R4400 and R10K have the watch registers, but they do not have mips
semantics, so are not currently usable with the watch register support.
This is why I initially was very conservative about the conditions
under which I probed watch registers. So I think it is good to try to
verify these things.
