How to generate Microcode FMP from Microcode PDB file

1) Copy directory UefiCpuPkg/Feature/Capsule/MicrocodeUpdatePdb to <Your Platform Package>/MicrocodeUpdatePdb.

2) Uncomment and update FILE DATA statement in <Your Platform Package>/MicrocodeUpdatePdb/MicrocodeCapsulePdb.fdf with path to a Microcode PDB file. The PDB file can placed in <Your Platform Package>/MicrocodeUpdatePdb or any other path.

FILE DATA = <your Microcode PDB file path>

Uncomment and update PLATFORM_NAME, FLASH_DEFINITION, OUTPUT_DIRECTORY section in <Your Platform Package>/MicrocodeUpdatePdb/MicrocodeCapsulePdb.dsc with .

PLATFORM_NAME                  = <Your Platform Package>
FLASH_DEFINITION               = <Your Platform Package>/MicrocodeCapsulePdb/MicrocodeCapsulePdb.fdf
OUTPUT_DIRECTORY               = Build/<Your Platform Package>

3) Use EDK II build tools to generate the Microcode FMP Capsule

build -p <Your Platform Package>/MicrocodeCapsulePdb/MicrocodeCapsulePdb.dsc

4) The Microcode FMP Capsule is generated at $(WORKSPACE)/$(OUTPUT_DIRECTORY)/$(TARGET)_$(TOOL_CHAIN_TAG)/FV/MicrocodeCapsule.Cap
