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