Known issues so far:
- le32/le64_to_cpu()'s and one cpu_to_le32 missing from tpm_crb.c
assuming that CRB driver would be used in big-endian architecture.
- I still have troubles having FIFO testing environment so it would
not be a big surprise if it had broke for some reason (help with
testing and/or bug fixes for FIFO would be highly appreciated).
Notes about the implementation:
- Reworked the code base to the direction that Jason Gunthorpe suggested.
- Moved to use devres in tpm_crb as Jason suggested.
- Did some groundwork for implementing Stefan Bergers suggestions to
I hope that it is now more in right direction than in my preview.
I'll push fixes on top of tpm2-v1 branch  and do not rebase it anymore
and therefore it is a good testing branch.
When things look good enough I'll create tpm2-v2 branch and prepare and
send a new patch set.
