1## @file 2# Instance of PCD Library using PCD Protocol. 3# 4# There are two PCD protocols as follows: 5# 1) PCD_PROTOCOL 6# It is EDKII implementation which support Dynamic/DynamicEx Pcds. 7# 2) EFI_PCD_PROTOCOL 8# It is defined by PI specification 1.2, Vol 3 which only support dynamicEx 9# type Pcd. 10# 11# For dynamicEx type PCD, it is compatible between PCD_PROTOCOL and EFI_PCD_PROTOCOL. 12# 13# This library instance uses the PCD_PROTOCOL to handle dynamic PCD request and use 14# EFI_PCD_PROTOCOL to handle dynamicEx type PCD. 15# 16# Note: A driver of type DXE_RUNTIME_DRIVER and DXE_SMM_DRIVER can only use this DxePcdLib 17# in their initialization without any issues to access Dynamic and DynamicEx PCD. They can't 18# access Dynamic and DynamicEx PCD in the implementation of runtime services and SMI handlers. 19# Because EFI_PCD_PROTOCOL is DXE protocol that is not aviable in OS runtime phase. 20# 21# Copyright (c) 2007 - 2014, Intel Corporation.
