/** @file
  This file defines:
  * the capsule vendor GUID for capsule variables and the HOB
  * the capsule variable name
  * the capsule GUID HOB data structure.
  The capsule HOB and variable can be used to store the capsule image start address and length.
  They are used by EDKII implementation of capsule update across a system reset.
  
  @par Note: EDKII implementation of capsule updating has obsolted this capsule GUID HOB data
             structur and used one UEFI Capsule HOB (defined in PI Specification 1.2) instead.
