Yes - microblaze gdb 5.0 does supoprt remote debugging.  Xilinx never 
intended to support (uC)linux, so they wrote their own gdbserver-type 
program to run on the host, which then communicates with a stub on the 
target via a proprietary serial interface.

So then, the question becomes:  is there any info online about providing 
new arch support for gdb/gdbserver?

Also looking at gdbserver version strings in the Makefiles - I see that 
gdbserver versions don't track gdb versions.  In both the gdb5.0 and 
gdb5.1 distributions, the gdbserver version string is 4.12.3...   ???

Thanks,
