1, PeiPcdLib use EFI_PEI_PCD_PPI defined in PI 1.2 to handle dynamicEx type PCD request.
2, DxePcdLib use EFI_PCD_PROTOCOL defined in PI 1.2 to handle dynamicEx type PCD request. 3, There is no change for dynamic type PCD. 4, Refine the INF's comments. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9473 6f19259b-4bc3-4df7-8a09-765794883524

#/** @file
|

# Instance of PCD Library using PCD PPI.
|
||||
#
|
||||
# There are two PCD PPIs as follows:
|
||||
# 1) PCD_PPI
|
||||
# It is EDKII implementation which support Dynamic/DynamicEx Pcds.
|
||||
# 2) EFI_PEI_PCD_PPI
|
||||
# It is defined by PI specification 1.2, Vol 3 which only support dynamicEx
|
||||
# type Pcd.
|
||||
# For dynamicEx type PCD, it is compatible between PCD_PPI and EFI_PEI_PCD_PPI.
|
||||
# This library instance uses the PCD_PPI to handle dynamic PCD request and use
|
||||
# EFI_PEI_PCD_PPI to handle dynamicEx type PCD.
|
||||
#
|
||||
# This library instance assume the PCD_PPI and EFI_PEI_PCD_PPI are both installed early.
|
||||
#
|
||||
# PCD Library that uses the PCD PPI to access Dynamic and DynamicEx PCD entries
