This change added a new instance of Tcg2PhysicalPresenceLib to support MM_STANDALONE type drivers. It centralizes the common routines into shared files and abstract the library constructor into corresponding files to implement each constructor function prototypes.

Handle TPM 2.0 physical presence requests from OS.
|
|
|
|
This library will handle TPM 2.0 physical presence request from OS.
|
|
|
|
Caution: This module requires additional review when modified.
|
|
This driver will have external input - variable.
|
|
This external input must be validated carefully to avoid security issue.
