Re: [PATCH v8 7/8] tpm: TPM 2.0 CRB Interface

Am Dienstag, 2. Dezember 2014, 23:31:19 schrieb Jarkko Sakkinen:

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.

If I apply it on top of security/next or linux-3.18-rc6 I get the following 
compile error:
