Hi John,

Thanks, I really appreciate your help on this.  I'll try this out 
today and see what we can get it to do.  Please keep us posted on
any updates.

regards,
Walt

Attached is a newer version of the archive, I'm homing in on getting 
this working.  You will need to freshen 
linux/arch/microblaze/kernel/ptrace.c and entry.S from CVS.

I've implemented support for gdb's remote "z/Z" packets - I'll spare you 
the details but it means we don't need custom versions of mb-gdb, and 
don't need to resort to the horrible hacks i mentioned earlier today.

Status now is that I can set at least one breakpoint, and have it 
trigger/trap correctly.  Stack frames seem to be OK, and I can inspect 
memory/local variables and function parameters etc.

Multiple breakpoints, and singlestepping don't work yet.   Anyway, it's 
getting there :)

Rgds,

John
