  The EFI_DRIVER_SUPPORTED_EFI_VERSION_PROTOCOL provides a
  mechanism for an EFI driver to publish the version of the EFI   
  specification it conforms to. This protocol must be placed on   
  the drivers image handle when the driver's entry point is   
  called.
  
  @param Length The size, in bytes, of the entire structure.
                Future versions of this specification may grow
                the size of the structure.
  
  @param firmwareVersion The version of the EFI specification
                         that this driver conforms to.
                         EFI_2_10_SYSTEM_TABLE_REVISION for this
                         version of this specification.
