Hi All,

Does Tianocore payload supports Variable services for storing variables in
SPI Flash

The default has
*In CorebootPayloadPkgIa32X64.dsc *
* MdeModulePkg/Universal/Variable/EmuRuntimeDxe/EmuVariableRuntimeDxe.inf*






Ideally it should have below drivers for Variable services to work

  CorebootPayloadPkg/PchSpi/RuntimeDxe/PchSpiRuntime.inf
  CorebootPayloadPkg/FvbRuntimeDxe/FvbRuntimeDxe.inf {
    <LibraryClasses>

FlashDeviceLib|CorebootPayloadPkg/Library/FlashDeviceLib/FlashDeviceLib.inf

NULL|CorebootPayloadPkg/Library/SpiFlashChipLib/SpiFlashChipWINBOND/SpiFlashChipWINBOND.inf

NULL|CorebootPayloadPkg/Library/SpiFlashChipLib/SpiFlashChipNUMONYX/SpiFlashChipNUMONYX.inf
  }
!endif
  MdeModulePkg/Universal/FaultTolerantWriteDxe/FaultTolerantWriteDxe.inf

Can any one comment on this for newer platforms like Skylake and KabyLake

Regards
Ranga
