I see there are patches queued in linux-next enabling some arm64 TPM CRB
support, which I believe are related.
As I have commented elsewhere [1], I think those have been taken
prematurely, and I'm not sure it's a good idea to enable this just yet,
due to that. There are spec issues to be addressed in the draft that is
still open.

Thanks,
Mark.
