Thanks Scott.

Apologize for not quoting the old email reference.

You did it again. :-)

I assumed the old archive content always will be in the trail.

It's in the archives (as I noted), but it's a pain to search for it
versus having relevant bits quoted.

Any idea whether the DBCR0 BRT bit actually works(??),

Do you have reason to believe that it might not?

if I add  DBCR0 under sys_debug context call? because this code seems
like direct porting and wondering why on first place not included under
debug_context call. 

Again, it was probably an oversight, but the people who might know for
sure are no longer reachable.

And also, anything special required for "server" family application code
porting here ?? as because in server family the trace exception used to viz
NORMAL exception proglog and uses SRR0 and SRR1 but in this ISA/embedded
case have dedicated DEBUG_DEBUG prolog and dedicated registers DSRR0 and
DSRR1.

IIRC the branch taken mechanism does have different semantics than the
equivalent mechanism on server.  You can find discussion of this in the
archives. :-)
