[PATCH v2 0/3] TPM2.0: Added eventlog support for TPM2.0

[Nayna Jain <nayna-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>]

Overview:
=========

This patch adds support for enabling securityfs for TPM2.0, currently
driver has eventlog support only for TPM1.2.
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.

Changelog v2:
=============

	* Fixes issues as given in feedback by Jason.
	* Adds documentation for device tree.
