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