What's currently implemented and working is the trace, memory loading
components, together with the hardware-supported printf() support
(similar to ARM CoreSight STM, printf()s in software are transmitted to
a host PC through the debug system).
For run-control debugging, including gdb support, we have early patches,
but it's not yet fully working. I didn't have time to work on it lately,
but a colleague of mine will start looking at it next week and pick up
the existing work, so we hope to get it integrated by early April.
If you need it earlier, I can get you access to the current patches, but
as I said, it requires some more work to be usable first.
