-// 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.
