- 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
- the image is unsupported. The function can optionally provide more detailed information on\r
- why the image is not a supported image.\r
- - Validate the data from VendorCode if not null. Image validation must be performed before\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
-\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

- reason to the caller.\r

- @param[in] VendorCode This enables vendor to implement vendor-specific firmware image update policy.\r
- Null indicates the caller did not specify the policy or use the default policy.\r
