[edk2-devel] [edk2-platforms][PATCH v4 05/41] IntelSiliconPkg: Add microcode FV PCDs

[Michael Kubacki]

Unfortunately, those cannot be used in the silicon packages.

This is not new to this series, see existing code:

https://github.com/tianocore/edk2-platforms/blob/086a3a3ce6c42c859ee5943eb2c4b6edcefdc241/Silicon/Intel/KabylakeSiliconPkg/SiPkg.dec#L460

https://github.com/tianocore/edk2-platforms/blob/086a3a3ce6c42c859ee5943eb2c4b6edcefdc241/Silicon/Intel/CoffeelakeSiliconPkg/SiPkg.dec#L481

https://github.com/tianocore/edk2-platforms/blob/086a3a3ce6c42c859ee5943eb2c4b6edcefdc241/Silicon/Intel/TigerlakeSiliconPkg/SiPkg.dec#L845

This series consolidates them to one silicon package declaration.

We can clean up further but this series has been out for 2+ months, 
rebasing 40 patches is costly, and incremental changes can continue to 
be made in the future. I originally made this series to prepare the code 
for some Standalone MM changes and those are still waiting to be rebased.
