As discussed during the thread on [0] here are my out of tree debug patches. These are only really for reference not expected for merge, and I'm not even sure it's worthy of an RFC tag. That said, if there are parts here that should perhaps be extracted for integration let me know and I'll split things out if relevant. The register extraction and decode is probably something that could be handled in userspace now anyway with something like Tomi's rwmem debug tool [1]. I've used that for other devices, but not used it on vsp1 yet.
