[edk2-devel] [PATCH v1] Intel/WhiskeylakeOpenBoardPkg: Simplify microcode related PCD usage

[Jason Lou]

From: Jason Lou <yun.lou at intel.com>

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3334

There are following PCDs in IntelFsp2WrapperPkg for microcode location:

* IntelFsp2WrapperPkg:
  PcdCpuMicrocodePatchAddress
  PcdCpuMicrocodePatchRegionSize
  PcdFlashMicrocodeOffset

The change simplify the platform code to use following PCDs instead:
* MinPlatformPkg
  PcdFlashFvMicrocodeOffset
  PcdFlashFvMicrocodeBase = $(BIOS_BASE) + PcdFlashFvMicrocodeOffset
  PcdFlashFvMicrocodeSize
  PcdMicrocodeOffsetInFv <NEW>
