Detailed Description

This module implements TCG EFI Protocol.

Caution: This module requires additional review when modified. This driver will have external input - TcgDxePassThroughToTpm This external input must be validated carefully to avoid security issue like buffer overflow, integer overflow.

TcgDxePassThroughToTpm() will receive untrusted input and do basic validation.
