Jarkko Sakkinen 30fc8d138e 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.

---help---
If you have a TPM security chip in your system, which
implements the Trusted Computing Group's specification,
say Yes and it will be accessible from within Linux. For
more information see <http://www.trustedcomputinggroup.org>.
An implementation of the Trusted Software Stack (TSS), the
userspace enablement piece of the specification, can be
obtained at: <http://sourceforge.net/projects/trousers>. To
compile this driver as a module, choose M here; the module
will be called tpm. If unsure, say N.
Notes:
1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
and CONFIG_PNPACPI.
2) Without ACPI enabled, the BIOS event log won't be accessible,
which is required to validate the PCR 0-7 values.
