  This module collects performance data for MM driver boot records and S3 Suspend Performance Record.

  This module registers report status code listener to collect performance data
  for MM driver boot records and S3 Suspend Performance Record.

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

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