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.
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
