I think the C looks more confusing than the assembly, but I understand
there are folks who feel compelled to write micro-controller code in a
high-level language.  :)

It definitely opens the door to more users.

Looks very interesting.  The methods they're using to pass data around
could be quite handy for our use, as long as we can do them in userland.

We might also be able to allocate some buffer memory and get that
locked in place and flagged properly as non-cacheable and side-step
the issue that way.

Thanks for the update!
