# Module produces PciCfgPpi2 on top of PciCfgPpi. It also updates the \r
# PciCfg2Ppi pointer in the EFI_PEI_SERVICES upon a installation of\r
# EcpPeiPciCfgPpi. \r
#\r
# EcpPeiPciCfgPpi is installed by a framework module which\r
# produce PciCfgPpi originally. Such framework module is updated based on the \r
# following rule to install EcpPeiPciCfgPpi instead of updating the PciCfg pointer\r
# in the Framework PeiServicesTable: \r
# \r
# Search pattern:\r
# 	   PeiServices->PciCfg = <*>;\r
# Replace pattern:\r
#         {\r
#           static EFI_PEI_PPI_DESCRIPTOR gEcpPeiPciCfgPpiList = {\r
#             (EFI_PEI_PPI_DESCRIPTOR_PPI | EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST),\r
#             &gEcpPeiPciCfgPpiGuid,\r
#             <*>\r
#           };\r
#           (**PeiServices).InstallPpi (PeiServices, &gEcpPeiPciCfgPpiList);\r
#         }\r
# \r
# In addition, the PeiServicesTable definition in PeiApi.h is updated to\r
# \r
# struct _EFI_PEI_SERVICES {\r
#   EFI_TABLE_HEADER              Hdr;\r
#   ...\r
# \r
#   //\r
#   // Pointer to PPI interface\r
#   //\r
# #if (PI_SPECIFICATION_VERSION < 0x00010000)\r
# \r
#   PEI_CPU_IO_PPI                 *CpuIo;\r
#   ECP_PEI_PCI_CFG_PPI        *PciCfg;  //Changed.\r
# #else\r
# ...\r
# #endif\r
# \r
# };\r
# \r
# This change enable the detection of code segment which invokes PeiServices->PciCfg->Modify.\r
# Such code causes a build break as ECP_PEI_PCI_CFG_PPI does not has "Modify" field. \r
# This should be updated to a call to PeiLibPciCfgModify as shown below:\r
# \r
# Search pattern:\r
# 		*->Modify(<*>); \r
# Replace pattern:\r
# 		PeiLibPciCfgModify(<*>);\r
#\r
# PIWG's PI specification replaces Inte's EFI Specification 1.10.\r
# EFI_PEI_PCI_CFG_PPI defined in Inte's EFI Specification 1.10 is replaced by\r
# EFI_PEI_PCI_CFG2_PPI in PI 1.0.\r
# This module produces PciCfgPpi on top of PciCfgPpi2. This module is used on platform when both of\r
# these two conditions are true:\r
# 1) Framework module present that produces PCI CFG PPI  AND\r
# 2) PI module that produces PCI CFG2 is not present\r
