With this flag, the LockBox can be restored in S3 resume only.
The LockBox can not be restored after SmmReadyToLock in normal boot
and after EndOfS3Resume in S3 resume.
It can not be set together with LOCK_BOX_ATTRIBUTE_RESTORE_IN_PLACE.

After IOMMU is enabled in S3, original solution with SMM device
code (OpalPasswordSmm) to unlock OPAL device for S3 will not work
as the DMA operation will be aborted without granted DMA buffer.
Instead, this solution is to add OpalPasswordPei to eliminate
SMM device code, and OPAL setup UI produced by OpalPasswordDxe
will be updated to send requests (set password, update password,
and etc), and then the requests will be processed in next boot
before SmmReadyToLock, password and device info will be saved to
lock box used by OpalPasswordPei to unlock OPAL device for S3.

+
+ @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
+ @param[in] ControllerHandle The Handle of the controller to start. This Handle
+ must support a protocol interface that supplies
+ an I/O abstraction to the driver.

+ parameter is ignored by device drivers, and is optional for bus
+ drivers. For a bus driver, if this parameter is NULL, then handles

+ If this parameter is not NULL and the first Device Path Node is
+ not the End of Device Path Node, then only the Handle for the
+ child device specified by the first Device Path Node of
+ RemainingDevicePath is created by this driver.
+ If the first Device Path Node of RemainingDevicePath is

+ 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.
+
+ @param This Indicates a pointer to the calling context.
+ @param MediaId ID of the medium to receive data from.
+ @param Timeout The timeout, in 100ns units, to use for the execution
+ of the security protocol command. A Timeout value of 0
+ means that this function will wait indefinitely for the
+ security protocol command to execute. If Timeout is greater
+ than zero, then this function will return EFI_TIMEOUT
+ if the time required to execute the receive data command
+ is greater than Timeout.
+ @param SecurityProtocolId The value of the "Security Protocol" parameter of
+ the security protocol command to be sent.
+ @param SecurityProtocolSpecificData The value of the "Security Protocol Specific" parameter
+ of the security protocol command to be sent.
+ @param PayloadBufferSize Size in bytes of the payload data buffer.
+ @param PayloadBuffer A pointer to a destination buffer to store the security
+ protocol command specific payload data for the security
+ protocol command. The caller is responsible for having
+ either implicit or explicit ownership of the buffer.
+ @param PayloadTransferSize A pointer to a buffer to store the size in bytes of the
+ data written to the payload data buffer.
+
+ @retval EFI_SUCCESS The security protocol command completed successfully.
+ @retval EFI_WARN_BUFFER_TOO_SMALL The PayloadBufferSize was too small to store the available

Some comment:
1) I suggest we use grayoutif instead of suppressif, in the VFR page.
suppressif ( questionref(SupportedDisks) & ( 0x1 ) ) == 0;
2) BuildOpalDeviceInfoAta() - Do we need zero TempDevInfoAta->Password?
3) BuildOpalDeviceInfoNvme() - Do we need zero TempDevInfoNvme->Password?
4) OpalDriverPopUpPsidInput()/OpalDriverPopUpPasswordInput() - Do we need zero ZeroMem (Mask, sizeof (Mask)) before any return NULL?
Thank you

Thanks for the great comments.
I just sent the V2 patch series for review with the comments addressed.
Thanks,

Subject: RE: [PATCH 4/7] SecurityPkg OpalPassword: Add solution without SMM device code
Some comment:
1) I suggest we use grayoutif instead of suppressif, in the VFR page.
suppressif ( questionref(SupportedDisks) & ( 0x1 ) ) == 0;
2) BuildOpalDeviceInfoAta() - Do we need zero TempDevInfoAta->Password?
3) BuildOpalDeviceInfoNvme() - Do we need zero TempDevInfoNvme->Password?
4) OpalDriverPopUpPsidInput()/OpalDriverPopUpPasswordInput() - Do we need zero ZeroMem (Mask, sizeof (Mask)) before any return NULL?
Thank you

- 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.
-
- @param This Indicates a pointer to the calling context.
- @param MediaId ID of the medium to receive data from.
- @param Timeout The timeout, in 100ns units, to use for the execution
- of the security protocol command. A Timeout value of 0
- means that this function will wait indefinitely for the
- security protocol command to execute. If Timeout is greater
- than zero, then this function will return EFI_TIMEOUT
- if the time required to execute the receive data command
- is greater than Timeout.
- @param SecurityProtocolId The value of the "Security Protocol" parameter of
- the security protocol command to be sent.
- @param SecurityProtocolSpecificData The value of the "Security Protocol Specific" parameter
- of the security protocol command to be sent.
- @param PayloadBufferSize Size in bytes of the payload data buffer.
- @param PayloadBuffer A pointer to a destination buffer to store the security
- protocol command specific payload data for the security
- protocol command. The caller is responsible for having
- either implicit or explicit ownership of the buffer.
- @param PayloadTransferSize A pointer to a buffer to store the size in bytes of the
- data written to the payload data buffer.
-
- @retval EFI_SUCCESS The security protocol command completed successfully.
- @retval EFI_WARN_BUFFER_TOO_SMALL The PayloadBufferSize was too small to store the available
- data from the device. The PayloadBuffer contains the truncated data.
- @retval EFI_UNSUPPORTED The given MediaId does not support security protocol commands.
- @retval EFI_DEVICE_ERROR The security protocol command completed with an error.
- @retval EFI_NO_MEDIA There is no media in the device.
