 330   Tests to see if this driver supports a given controller. If a child device is provided,
 331   it further tests to see if this driver supports creating a handle for the specified child device.
 332
 333   This function checks to see if the driver specified by This supports the device specified by
 334   ControllerHandle. Drivers will typically use the device path attached to
 335   ControllerHandle and/or the services from the bus I/O abstraction attached to
 336   ControllerHandle to determine if the driver supports ControllerHandle. This function
 337   may be called many times during platform initialization. In order to reduce boot times, the tests
 338   performed by this function must be very small, and take as little time as possible to execute. This
 339   function must not change the state of any hardware devices, and this function must be aware that the
 340   device specified by ControllerHandle may already be managed by the same driver or a
 341   different driver. This function must match its calls to AllocatePages() with FreePages(),
 342   AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
 343   Since ControllerHandle may have been previously started by the same driver, if a protocol is
 344   already in the opened state, then it must not be closed with CloseProtocol(). This is required
 345   to guarantee the state of ControllerHandle is not modified by this function.
 346
 347   @param[in]  This                 A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
 348   @param[in]  ControllerHandle     The handle of the controller to test. This handle
 349                                    must support a protocol interface that supplies
 350                                    an I/O abstraction to the driver.
 351   @param[in]  RemainingDevicePath  A pointer to the remaining portion of a device path.  This
 352                                    parameter is ignored by device drivers, and is optional for bus
 353                                    drivers. For bus drivers, if this parameter is not NULL, then
 354                                    the bus driver must determine if the bus controller specified
 355                                    by ControllerHandle and the child controller specified
 356                                    by RemainingDevicePath are both supported by this

 397                                    parameter is ignored by device drivers, and is optional for bus

 903   of one or more commands sent by SendData.
 904
 905   The ReceiveData function sends a security protocol command to the given MediaId.
 906   The security protocol command sent is defined by SecurityProtocolId and contains
 907   the security protocol specific data SecurityProtocolSpecificData. The function
 908   returns the data from the security protocol command in PayloadBuffer.
 909
 910   For devices supporting the SCSI command set, the security protocol command is sent
 911   using the SECURITY PROTOCOL IN command defined in SPC-4.
 912
 913   For devices supporting the ATA command set, the security protocol command is sent
 914   using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
 915   is non-zero.
 916
 917   If the PayloadBufferSize is zero, the security protocol command is sent using the
 918   Trusted Non-Data command defined in ATA8-ACS.
 919
 920   If PayloadBufferSize is too small to store the available data from the security
 921   protocol command, the function shall copy PayloadBufferSize bytes into the
 922   PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.

 925   the function shall return EFI_INVALID_PARAMETER.
 926
 927   If the given MediaId does not support security protocol commands, the function shall
 928   return EFI_UNSUPPORTED. If there is no media in the device, the function returns
 929   EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device,
 930   the function returns EFI_MEDIA_CHANGED.
 931
 932   If the security protocol fails to complete within the Timeout period, the function
 933   shall return EFI_TIMEOUT.
 934
 935   If the security protocol command completes without an error, the function shall
 936   return EFI_SUCCESS. If the security protocol command completes with an error, the

 943                                        means that this function will wait indefinitely for the
 944                                        security protocol command to execute. If Timeout is greater

 946                                        if the time required to execute the receive data command

1061   Typically, there are 2 mechanism for resetting eDrive. They are:
1062   1. TPer Reset through IEEE 1667 protocol.
1063   2. TPer Reset through native TCG protocol.
1064   This routine will detect what protocol the attached eDrive comform to, TCG or
1065   IEEE 1667 protocol. Then send out TPer Reset command separately.
