Has a RFC of the kernel driver been posted yet? I'm curious on how it
Linux backend integrates with other devices.

This PDF seems to include a fair number of extra devices - including an
RPMB device I'm quite interested in. Is this because you are building
from a tree with a bunch of rolled up updates?

In fact looking closer at the rendered version it seems to be missing
device id 32.

/me wonders off to look at the make tooling in the upstream repo to see
if things can be tweaked a bit.
