[PATCH 0/2] tcgbios: Use the proper hashes for the TPM 2 PCR banks

[Stefan Berger]

This PR adds the implementations for sha{256, 384, 512} and makes use
of the hash implementation when extending the PCRs of the respective
banks rather than always using the sha1 and zero-padding it for the PCR
banks of a TPM 2.

Regards,
    Stefan
