[edk2-devel] [Patch V2 07/12] UefiPayloadPkg: Fix up UPL Pcd database

Wed Jun 23 02:52:30 UTC 2021
V1:
Edk2 bootloader will pass the pei pcd database, and UPL also contain a
PCD database.
Dxe PCD driver has the assumption that the two PCD database can be
catenated and the local token number should be successive。
This patch will manually fix up the UPL PCD database to meet that
assumption.
V2:
Update the function comments
