I'm definitely for extending trusted keys beyond TPMs. Before that can be
done, however, the current mess needs to be cleaned up.
I did a lot of work recently  to clean up TPM transmit code to better
suited to be used outside of the TPM drivers (remove recursive calls,
put the whole stack use tpm_buf for everything).
What still needs to be done is to move tpm_buf stuff to include/linux in
order to be usable in the keyring code. Also for TPM 2.0 trusted keys,
TPM2 constants need to be moved to include/linux. For the latter, I'd
suggest to move all protocol constants there and not just what is
required for trusted keys. Better to have them in one place.
