tpm: TPM 2.0 CRB Interface
tpm_crb is a driver for TPM 2.0 Command Response Buffer (CRB) Interface as defined in PC Client Platform TPM Profile (PTP) Specification. Only polling and single locality is supported as these are the limitations of the available hardware, Platform Trust Techonlogy (PTT) in Haswell CPUs. The driver always applies CRB with ACPI start because PTT reports using only ACPI start as start method but as a result of my testing it requires also CRB start.
