2 | This PEIM initialize platform for MRC, following action is performed,\r | |
3 | 1. Initizluize GMCH\r | |
4 | 2. Detect boot mode\r | |
5 | 3. Detect video adapter to determine whether we need pre allocated memory\r | |
6 | 4. Calls MRC to initialize memory and install a PPI notify to do post memory initialization.\r | |
7 | This file contains the main entrypoint of the PEIM.\r | |
