> module extend the TCG event.
> There is more and more use case in PEI phase that a PEIM need extend TCG
> event, such as BootGuard, FSP, Microcode measurement. Currently, we dont
> have API to do that so that each module need create TCG/TCG2 event log,
> which is a burden.
>
> This bugzilla requests to add PeiTpmMeasurementLib instance.
>
> The implementation includes:
> 1) A EDKII_TCG_PPI which abstracts the HashLogExtendEvent service.
> 2) A PeiTpmMeasurementLib instance, so that a PEIM can call this API to
> add TCG event.
