This patch series add the support of measurement
descibed in TCG PC Client PFP spec(Version 1.05 Revision 23).
Eventlog generated with this patch series are tested on
the aarch64 based machine(Socionext Developerbox) and fTPM
running on OP-TEE.
The eventlog result is almost same result as the one
generated by edk2 running on the Devloperbox and Secure96.
This patch series does not cover all measurement requirements
described in TCG spec, the remaining items will be supported
in the future.
Major missing items in TCG PC Client PFP spec:
1) If the secure boot variables are updated after they are
initially measured in PCR[7] and before ExitBootServices()
has completed, the platform MAY be restarted OR the variables
MUST be remeasured into PCR[7].
2) SMBIOS structure measurement
3) "DeployedMode" and "AuditMode" measurement
4) EV_EFI_GPT_EVENT event
5) Measurement of U-boot itself. I assume U-boot measurement will be done
by the former firmware such as trusted firmware.
