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