+A splash source location can describe either storage with raw data, a storage
+formatted with a file system or a FIT image. In case of a filesystem, the splash
+screen data is loaded as a file. The name of the splash screen file can be
+controlled with the environment variable "splashfile".
+
+To enable loading the splash image from a FIT image, CONFIG_FIT must be
+enabled. Struct splash_location field 'name' should match the splash image
+name within the FIT and the FIT should start at the 'offset' field address in
+the specified storage.
