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.
