Pretty cool eh?

Have you tested it on real hardware?

Otherwise I can test it if I have a git branch
I can pull in and compile.

Another target I had in mind was the Integrator which
incidentally supports a bunch of the old noMMU core
tiles where we can swap in an ARM946, which I guess
could work with this?

Not really related but I don't mind.
