558 Tests to see if this driver supports a given controller. If a child device is provided,
559 it further tests to see if this driver supports creating a handle for the specified child device.
560
561 This function checks to see if the driver specified by This supports the device specified by
562 ControllerHandle. Drivers will typically use the device path attached to
563 ControllerHandle and/or the services from the bus I/O abstraction attached to
564 ControllerHandle to determine if the driver supports ControllerHandle. This function
565 may be called many times during platform initialization. In order to reduce boot times, the tests
566 performed by this function must be very small, and take as little time as possible to execute. This
567 function must not change the state of any hardware devices, and this function must be aware that the
568 device specified by ControllerHandle may already be managed by the same driver or a
569 different driver. This function must match its calls to AllocatePages() with FreePages(),
570 AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
571 Since ControllerHandle may have been previously started by the same driver, if a protocol is
572 already in the opened state, then it must not be closed with CloseProtocol(). This is required
573 to guarantee the state of ControllerHandle is not modified by this function.
574
575 @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
576 @param[in] ControllerHandle The handle of the controller to test. This handle
577 must support a protocol interface that supplies
578 an I/O abstraction to the driver.
579 @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
580 parameter is ignored by device drivers, and is optional for bus
581 drivers. For bus drivers, if this parameter is not NULL, then
582 the bus driver must determine if the bus controller specified
583 by ControllerHandle and the child controller specified
584 by RemainingDevicePath are both supported by this
585 bus driver.
586
587 @retval EFI_SUCCESS The device specified by ControllerHandle and
588 RemainingDevicePath is supported by the driver specified by This.
589 @retval EFI_ALREADY_STARTED The device specified by ControllerHandle and
590 RemainingDevicePath is already being managed by the driver
591 specified by This.
592 @retval EFI_ACCESS_DENIED The device specified by ControllerHandle and

700 1. ControllerHandle must be a valid EFI_HANDLE.
701 2. If RemainingDevicePath is not NULL, then it must be a pointer to a naturally aligned
702 EFI_DEVICE_PATH_PROTOCOL.
703 3. Prior to calling Start(), the Supported() function for the driver specified by This must
704 have been called with the same calling parameters, and Supported() must have returned EFI_SUCCESS.
705
706 @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
707 @param[in] ControllerHandle The handle of the controller to start. This handle
708 must support a protocol interface that supplies
709 an I/O abstraction to the driver.
710 @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
711 parameter is ignored by device drivers, and is optional for bus
712 drivers. For a bus driver, if this parameter is NULL, then handles
713 for all the children of Controller are created by this driver.
714 If this parameter is not NULL and the first Device Path Node is
715 not the End of Device Path Node, then only the handle for the
716 child device specified by the first Device Path Node of
717 RemainingDevicePath is created by this driver.
718 If the first Device Path Node of RemainingDevicePath is
719 the End of Device Path Node, no child handle is created by this
720 driver.

1475 The security protocol command sent is defined by SecurityProtocolId and contains
1476 the security protocol specific data SecurityProtocolSpecificData. The function
1477 returns the data from the security protocol command in PayloadBuffer.
1478
1479 For devices supporting the SCSI command set, the security protocol command is sent
1480 using the SECURITY PROTOCOL IN command defined in SPC-4.
1481
1482 For devices supporting the ATA command set, the security protocol command is sent
1483 using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
1484 is non-zero.
1485
1486 If the PayloadBufferSize is zero, the security protocol command is sent using the
1487 Trusted Non-Data command defined in ATA8-ACS.
1488
1489 If PayloadBufferSize is too small to store the available data from the security
1490 protocol command, the function shall copy PayloadBufferSize bytes into the
1491 PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.

1494 the function shall return EFI_INVALID_PARAMETER.

1497 return EFI_UNSUPPORTED. If there is no media in the device, the function returns
1498 EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device,
1499 the function returns EFI_MEDIA_CHANGED.

1501 If the security protocol fails to complete within the Timeout period, the function
1502 shall return EFI_TIMEOUT.

1510 @param Timeout The timeout, in 100ns units, to use for the execution
1511 of the security protocol command. A Timeout value of 0
1512 means that this function will wait indefinitely for the
1513 security protocol command to execute. If Timeout is greater
1514 than zero, then this function will return EFI_TIMEOUT
1515 if the time required to execute the receive data command
1516 is greater than Timeout.

1518 the security protocol command to be sent.

1520 of the security protocol command to be sent.

1528
1529 @retval EFI_SUCCESS The security protocol command completed successfully.
1530 @retval EFI_WARN_BUFFER_TOO_SMALL The PayloadBufferSize was too small to store the available
