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 remaing 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.
