   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.
