  This file includes a memory call back function notified when MRC is done,\r
  following action is performed in this file,\r
    1. ICH initialization after MRC.\r
    2. SIO initialization.\r
    3. Install ResetSystem and FinvFv PPI.\r
    4. Set MTRR for PEI\r
    5. Create FV HOB and Flash HOB\r
