[SeaBIOS] [PATCH v2 0/3] Fix CRB probing to work with real hardware

[Stefan Berger]

This series of patches attempts to fix the probing of the CRB interface
for real hardware.

Stephen Douthit tested the changes on real hardware and it seems to
fix an existing problem.

Stefan

v1->v2:
  - test LOC_STATE register for set tpmRegValidSts flag and unset
    locAssigned flag without writing to any other registers

Stefan Berger (3):
  tpm: Wait for tpmRegValidSts flag on CRQ interface before probing
  tpm: revert return values for successful/failed CRB probing
  tpm: when CRB is active, select, lock it, and check addresses
