+ Updates a firmware device with a new firmware image. This function returns\r
+ EFI_UNSUPPORTED if the firmware image is not updatable. If the firmware image\r

+ Return EFI_ABORTED if the image is not supported. Additional details\r

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