+ 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

+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
