// The HiiAddPackages() library function requires that any controller (or
// image) handle, to be associated with the HII packages under installation, be
// "decorated" with a device path. The tradition seems to be a vendor device
// path.
//
// We'd like to associate our HII packages with the driver's image handle. The
// first idea is to use the driver image's device path. Unfortunately, loaded
// images only come with an EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL (not the
// usual EFI_DEVICE_PATH_PROTOCOL), ie. a different GUID. In addition, even the
// EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL interface may be NULL, if the image
// has been loaded from an "unnamed" memory source buffer.
//
// Hence let's just stick with the tradition -- use a dedicated vendor device
// path, with the driver's FILE_GUID.
