-Module produce PciCfgPpi on top of PciCfgPpi2.
-
-PIWG's PI specification replaces Inte's EFI Specification 1.10.
-EFI_PEI_PCI_CFG_PPI defined in Inte's EFI Specification 1.10 is replaced by
-EFI_PEI_PCI_CFG2_PPI in PI 1.0.
-This module produces PciCfgPpi on top of PciCfgPpi2. This module is used on platform when both of
-these two conditions are true:
-1) Framework module is present that consumes PCI CFG AND
-2) PI module is present that produces PCI CFG2 but not PCI CFG
-
-The Usage of this module is rare since EDK II module IntelFrameworkModulePkg\Universal\PcatSingleSegmentPciCfgPei\PcatSingleSegmentPciCfgPei.inf
-that produce PCI CFG2 can also produce PCI CFG by setting Pcd Feature Flag gEfiIntelFrameworkModulePkgTokenSpaceGuid.PcdPciCfgDisable
-to FALSE.
