There are use cases which not all FVs need be migrated from TempRam to
permanent memory before TempRam tears down. This new guid is introduced
to avoid unnecessary FV migration to improve boot performance. Platform
can publish MigrationInfo hob with this guid to customize FV migration
info, and PeiCore will only migrate FVs indicated by this Hob info.

This is a backwards compatible change, PeiCore will check MigrationInfo
hob before migration. If MigrationInfo hobs exists, only migrate FVs
recorded by hobs. If MigrationInfo hobs not exists, migrate all FVs to
permanent memory.

In Tcg driver, when MigratedFvInfo hob is detected, existing code logic
is assuming FV raw data is already copied, and raw data base address is
also recorded. Due to the new PeiCore change, the platform can publish
hob to indicate raw data need be copied or not along with FV migration.

Two cases need be considered to skip copy for boot performance: The first
case is FV is not expected to be measured in post-mem phase, we should
use MeasurementExcludedPpiGuid to skip measurement. The second case is
FV raw data has no need to do rebase operation after migration, then
measurement should calculate hash directly from FV base address.

Hi Liming and Kumar

Could you help review this v5 patch:

MdeModulePkg: Support customized FV Migration Information: 
https://github.com/fanwang2intel/edk2/commit/83c55a73107bfb13df1d8b522e0ea1d18ef3d86b

SecurityPkg: Support customized FV Migration Information
https://github.com/fanwang2intel/edk2/commit/6f7e955f1d63a875f69ebc084885e76610acc722

v5: 
- Remove RemoveFvHobsInTemporaryMemory() since no consumer will call this API now.
- Separate patches to different packages. 

Best Regards
Fan

Hi Liming

The V5 patches have past test. Could you help merge these two patches? Or I need find Rahul to merge the one in SecurityPkg?

https://github.com/tianocore/edk2/pull/5180
https://github.com/tianocore/edk2/pull/5181

They are totally independent and merge MdeModulePkg patch only will not impact any existing code.

Best Regards
Fan
