[[PATCH v2] tpm: Add wolfTPM library support for TPM 2.0 00/12] *** SUBJECT HERE ***

[Ilias Apalodimas]

Hi David,

Apologies for the very late reply, but I am overloaded and this is going some time to review.

For starters the CI failed to pass the docs. Please have a look and update
them properly

Cheers
