Can you elaborate on this a bit, both in the code comment and the
commit message.
Will do in v3. Basically the TPM 2 code has been 'fixed' to reflect the
pcclient profile more closely and due to the change in PCRs that belong
to the 'TCB group' the response of the TPM2_Pcrread command now returns
a slightly different value for the pcrUpdateCounter value, which
unfortunately breaks the test cases. Leaving the TPM 2 as it was wasn't
a long-term option.
