   2 // Instance of PCD Library using PCD PPI.
   3 //
   4 // There are two PCD PPIs as follows:
   5 // 1) PCD_PPI
   6 // It is EDKII implementation which support Dynamic/DynamicEx Pcds.
   7 // 2) EFI_PEI_PCD_PPI
   8 // It is defined by PI specification 1.2, Vol 3 which only support dynamicEx
   9 // type Pcd.
  10 // For dynamicEx type PCD, it is compatible between PCD_PPI and EFI_PEI_PCD_PPI.
  11 // This library instance uses the PCD_PPI to handle dynamic PCD request and use
  12 // EFI_PEI_PCD_PPI to handle dynamicEx type PCD.
  13 //
  14 // This library instance assume the PCD_PPI and EFI_PEI_PCD_PPI are both installed early.

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 assumes that PCD_PPI and EFI_PEI_PCD_PPI are both installed early. The PCD Library that uses the PCD PPI to access Dynamic and DynamicEx PCD entries."
