REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2841
Currently, we have TCG/TCG2 protocol and DxeTpmMeasurementLib to let DXE
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.
