> Introduces a new library class FirmwareBootMediaInfoLib that is used to
> report the firmware boot media device. A default library instance is provided
> that always returns the firmware boot media is SPI flash. For platforms with
> other firmware boot media options, a board-specific instance of this library
> should be used instead to provide the correct firmware boot media device
> information.
