3 PCDs are defined assuming that microcode is put in the end of a FV:
PcdFlashFvMicrocodeBase: The base address of the microcode FV
PcdFlashFvMicrocodeSize: The size of the microcode FV
PcdFlashMicrocodeOffset: The microcode offset relative to the FV
base address
The 3 new PCDs are to replace the following existing PCDs in
MinPlatformPkg and IntelFsp2WrapperPkg.
The ones in MinPlatformPkg will be removed in a separate patch.
The ones in IntelFsp2WrapperPkg will be re-positioned as only using
inside IntelFsp2WrapperPkg\Library\SecFspWrapperPlatformSecLibSample.
Defining PCDs in IntelSiliconPkg is because certain close-source
silicon code depends on these PCDs but the silicon code cannot depend
on MinPlatformPkg.
MinPlatformPkg contains the below 3 PCDs:
PcdFlashFvMicrocodeBase: Same meaning as
IntelSiliconPkg.PcdFlashFvMicrocodeBase
PcdFlashFvMicrocodeSize: Same meaning as
IntelSiliconPkg.PcdFlashFvMicrocodeSize
PcdFlashFvMicrocodeOffset: The FV offset relative to the firmware
base address.
Note: MinPlatformPkg doesn't contain the PCD that tells the microcode
offset relative to the FV base address.
IntelFsp2WrapperPkg contains the below 3 PCDs:
PcdCpuMicrocodePatchAddress: Same meaning as
IntelSiliconPkg.PcdFlashFvMicrocodeBase
PcdCpuMicrocodePatchRegionSize: Same meaning as
IntelSiliconPkg.PcdFlashFvMicrocodeSize
PcdFlashMicrocodeOffset: Same meaning as
IntelSiliconPkg.PcdFlashMicrocodeOffset
