4 | This library will handle TPM 2.0 physical presence request from OS.\r | |
5 | \r | |
6 | Caution: This module requires additional review when modified.\r | |
7 | This driver will have external input - variable.\r | |
8 | This external input must be validated carefully to avoid security issue.\r | |
