The TPer Reset operation would be moved into SecurityPkg/Tcg/ MemoryOverwriteControl/TcgMor.inf module and be triggered at EndOfDxe. By this way, all encrypted drives which produce EFI_STORAGE_SECURITY_ RPOTOCOL interface would be force reset when MOR is set.

  Tests to see if this driver supports a given controller. If a child device is provided,
 | 
						|
  it further tests to see if this driver supports creating a handle for the specified child device.
 | 
						|
 | 
						|
  This function checks to see if the driver specified by This supports the device specified by
 | 
						|
  ControllerHandle. Drivers will typically use the device path attached to
 | 
						|
  ControllerHandle and/or the services from the bus I/O abstraction attached to
 | 
						|
  ControllerHandle to determine if the driver supports ControllerHandle. This function
 | 
						|
  may be called many times during platform initialization. In order to reduce boot times, the tests
 | 
						|
  performed by this function must be very small, and take as little time as possible to execute. This
 | 
						|
  function must not change the state of any hardware devices, and this function must be aware that the
 | 
						|
  device specified by ControllerHandle may already be managed by the same driver or a
 | 
						|
  different driver. This function must match its calls to AllocatePages() with FreePages(),
 | 
						|
  AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
 | 
						|
  Since ControllerHandle may have been previously started by the same driver, if a protocol is
 | 
						|
  already in the opened state, then it must not be closed with CloseProtocol(). This is required
 | 
						|
  to guarantee the state of ControllerHandle is not modified by this function.

  Send a security protocol command to a device that receives data and/or the result

  of one or more commands sent by SendData.

  The ReceiveData function sends a security protocol command to the given MediaId.
 | 
						|
  The security protocol command sent is defined by SecurityProtocolId and contains
 | 
						|
  the security protocol specific data SecurityProtocolSpecificData. The function
 | 
						|
  returns the data from the security protocol command in PayloadBuffer.
 | 
						|
 | 
						|
  For devices supporting the SCSI command set, the security protocol command is sent
 | 
						|
  using the SECURITY PROTOCOL IN command defined in SPC-4.
 | 
						|
 | 
						|
  For devices supporting the ATA command set, the security protocol command is sent
 | 
						|
  using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
 | 
						|
  is non-zero.
 | 
						|
 | 
						|
  If the PayloadBufferSize is zero, the security protocol command is sent using the
 | 
						|
  Trusted Non-Data command defined in ATA8-ACS.
 | 
						|
 | 
						|
  If PayloadBufferSize is too small to store the available data from the security
 | 
						|
  protocol command, the function shall copy PayloadBufferSize bytes into the
 | 
						|
  PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.
 |

  If PayloadBuffer or PayloadTransferSize is NULL and PayloadBufferSize is non-zero,
 |

  the function shall return EFI_INVALID_PARAMETER.
 | 
						|
 | 
						|
  If the given MediaId does not support security protocol commands, the function shall
 | 
						|
  return EFI_UNSUPPORTED. If there is no media in the device, the function returns
 | 
						|
  EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device,
 | 
						|
  the function returns EFI_MEDIA_CHANGED.
 | 
						|
 | 
						|
  If the security protocol fails to complete within the Timeout period, the function
 | 
						|
  shall return EFI_TIMEOUT.
 | 
						|
 | 
						|
  If the security protocol command completes without an error, the function shall
 |

  return EFI_SUCCESS. If the security protocol command completes with an error, the

  function shall return EFI_DEVICE_ERROR.

/**

  Send a security protocol command to a device.
 | 
						|
 | 
						|
  The SendData function sends a security protocol command containing the payload
 | 
						|
  PayloadBuffer to the given MediaId. The security protocol command sent is
 | 
						|
  defined by SecurityProtocolId and contains the security protocol specific data
 | 
						|
  SecurityProtocolSpecificData. If the underlying protocol command requires a
 | 
						|
  specific padding for the command payload, the SendData function shall add padding
 | 
						|
  bytes to the command payload to satisfy the padding requirements.
 | 
						|
 | 
						|
  For devices supporting the SCSI command set, the security protocol command is sent
 | 
						|
  using the SECURITY PROTOCOL OUT command defined in SPC-4.
 | 
						|
 | 
						|
  For devices supporting the ATA command set, the security protocol command is sent
 | 
						|
  using one of the TRUSTED SEND commands defined in ATA8-ACS if PayloadBufferSize
 | 
						|
  is non-zero. If the PayloadBufferSize is zero, the security protocol command is
 | 
						|
  sent using the Trusted Non-Data command defined in ATA8-ACS.
 | 
						|
 | 
						|
  If PayloadBuffer is NULL and PayloadBufferSize is non-zero, the function shall
 | 
						|
  return EFI_INVALID_PARAMETER.
 | 
						|
 | 
						|
  If the given MediaId does not support security protocol commands, the function
 | 
						|
  shall return EFI_UNSUPPORTED. If there is no media in the device, the function
 | 
						|
  returns EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the
 | 
						|
  device, the function returns EFI_MEDIA_CHANGED.
 | 
						|
 | 
						|
  If the security protocol fails to complete within the Timeout period, the function
 | 
						|
  shall return EFI_TIMEOUT.
 | 
						|
 | 
						|
  If the security protocol command completes without an error, the function shall return
 | 
						|
  EFI_SUCCESS. If the security protocol command completes with an error, the function
 | 
						|
  shall return EFI_DEVICE_ERROR.
 | 
						|

 |

                                       means that this function will wait indefinitely for the

                                       security protocol command to execute. If Timeout is greater
