Overview: ========= Patch adds support for enabling securityfs for TPM2.0. The patch currently adds support for only binary_bios_measurements.
The structure for TPM2.0 is compliant with TCG Spec for 2.0 family. Also , the reading of data has the assumption that writer would have followed TCG Spec and so everything is in little-endian. The tpm device driver code has been refactored to: * Identify the TPM version - 1.2 or 2.0 * Calls corresponding compatible seq_ops for iterating over eventlog. Files Description: =================== * tpm-chip.c : Adds call to setup bios log for TPM2.0. * tpm2_of.c : Reads the device tree entries to find the location and size of event. * tpm_eventlog_init.c : Provides common initialization functions between TPM2.0 and TPM1.2 to setup securityfs entries and seq_ops iterator. The functions has been moved from tpm_eventlog.c into this file. * tpm_eventlog.c : Provides functions only specific to TPM1.2 version. Common initialization functions are moved to tpm_eventlog_init.c * tpm2_eventlog.c : Provides functions specific only for TPM2.0 eventlog format. * tpm2.h : Header file for TPM2.0 structures and functions.
