[PATCH v3 0/6] tpm: Support boot measurements

[Eddie James]

This series adds support for measuring the boot images more generically
than the existing EFI support. Several EFI functions have been moved to
the TPM layer. The series includes optional measurement from the bootm 
command.
A new test case has been added for the bootm measurement to test the new
path, and the sandbox TPM2 driver has been updated to support this use
case.

Changes since v2:
 - Add documentation.
 - Changed reserved memory address to the top of the RAM for sandbox dts.
 - Add measure state to booti and bootz.
 - Skip measurement for EFI images that should be measured

Changes since v1:
 - Refactor TPM layer functions to allow EFI system to use them, and
   remove duplicate EFI functions.
 - Add test case
 - Drop #ifdefs for bootm
 - Add devicetree measurement config option
 - Update sandbox TPM driver
