#/** @file
# Module produces PciCfgPpi2 on top of PciCfgPpi. It also updates the
# PciCfg2Ppi pointer in the EFI_PEI_SERVICES upon a installation of
# EcpPeiPciCfgPpi.
#
# EcpPeiPciCfgPpi is installed by a framework module which
# produce PciCfgPpi originally. Such framework module is updated based on the
# following rule to install EcpPeiPciCfgPpi instead of updating the PciCfg pointer
# in the Framework PeiServicesTable:
#
# Search pattern:
# PeiServices->PciCfg = <*>;
# Replace pattern:
# {
# static EFI_PEI_PPI_DESCRIPTOR gEcpPeiPciCfgPpiList = {
# (EFI_PEI_PPI_DESCRIPTOR_PPI | EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST),
# &gEcpPeiPciCfgPpiGuid,
# <*>
# };
# (**PeiServices).InstallPpi (PeiServices, &gEcpPeiPciCfgPpiList);
# }
#
# In addition, the PeiServicesTable definition in PeiApi.h is updated to
#
# struct _EFI_PEI_SERVICES {
# EFI_TABLE_HEADER Hdr;
# ...
#
# //
# // Pointer to PPI interface
# //
# #if (PI_SPECIFICATION_VERSION < 0x00010000)
#
# PEI_CPU_IO_PPI *CpuIo;
# ECP_PEI_PCI_CFG_PPI *PciCfg; //Changed.
# #else
# ...
# #endif
#
# };
#
# This change enable the detection of code segment which invokes PeiServices->PciCfg->Modify.
# Such code causes a build break as ECP_PEI_PCI_CFG_PPI does not has "Modify" field.
# This should be updated to a call to PeiLibPciCfgModify as shown below:
#
# Search pattern:
# *->Modify(<*>);
# Replace pattern:
# PeiLibPciCfgModify(<*>);
#
# 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 present that produces PCI CFG PPI AND
# 2) PI module that produces PCI CFG2 is not present
#
# PEIM to provide the Variable functionality.
