+ Updates the firmware image of the device.\r
+\r
+ This function updates the hardware with the new firmware image.\r
+ This function returns EFI_UNSUPPORTED if the firmware image is not updatable.\r
+ If the firmware image is updatable, the function should perform the following minimal validations\r
+ before proceeding to do the firmware image update.\r
+ - Validate the image authentication if image has attribute\r
+ IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns\r
+ EFI_SECURITY_VIOLATION if the validation fails.\r
+ - Validate the image is a supported image for this device. The function returns EFI_ABORTED if\r

+ VendorCode data validation. VendorCode data is ignored or considered invalid if image\r
+ validation failed. The function returns EFI_ABORTED if the data is invalid.\r

+ VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if\r
+ the caller did not specify the policy or use the default policy. As an example, vendor can implement\r
+ a policy to allow an option to force a firmware image update when the abort reason is due to the new\r
+ firmware image version is older than the current firmware image version or bad image checksum.\r
+ Sensitive operations such as those wiping the entire firmware image and render the device to be\r
+ non-functional should be encoded in the image itself rather than passed with the VendorCode.\r
