In my development of a stub for a home-grown
embedded environment I am now looking at the
'Z' and 'z' messages (insert/remove break and
watchpoints).
Is there an example stub that I should study?
Maybe even an MPC8xx or IBM405 implementation?

RedBoot has a stub which uses the Z packets. RedBoot also has
existing ports for both 8xx and 4xx cpus.

I have grabbed a copy of the sources. I was hoping
that I would see an example of setting up hardware
breakpoints and watchpoints. It looks to me like
this code supports only software breakpoints. Am
I mistaken?
