+/**
+ Updates the firmware image of the device.
+
+ This function updates the hardware with the new firmware image.
+ This function returns EFI_UNSUPPORTED if the firmware image is not updatable.
+ If the firmware image is updatable, the function should perform the following minimal validations
+ before proceeding to do the firmware image update.
+ - Validate the image authentication if image has attribute
+ IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns
+ EFI_SECURITY_VIOLATION if the validation fails.
+ - Validate the image is a supported image for this device. The function returns EFI_ABORTED if
+ the image is unsupported. The function can optionally provide more detailed information on
+ why the image is not a supported image.
+ - Validate the data from VendorCode if not null. Image validation must be performed before
+ VendorCode data validation. VendorCode data is ignored or considered invalid if image
+ validation failed. The function returns EFI_ABORTED if the data is invalid.
+
+ VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if
+ the caller did not specify the policy or use the default policy. As an example, vendor can implement
+ a policy to allow an option to force a firmware image update when the abort reason is due to the new
+ firmware image version is older than the current firmware image version or bad image checksum.
+ Sensitive operations such as those wiping the entire firmware image and render the device to be
+ non-functional should be encoded in the image itself rather than passed with the VendorCode.
+ AbortReason enables vendor to have the option to provide a more detailed description of the abort
+ reason to the caller.
