+# U-Boot firmware supports the booting of images in the Flattened Image
+# Tree (FIT) format. The FIT format uses a device tree structure to
+# describe a kernel image, device tree blob, ramdisk, etc. This script
+# creates an Image Tree Source (.its file) which can be passed to the
+# 'mkimage' utility to generate an Image Tree Blob (.itb file). The .itb
+# file can then be booted by U-Boot (or other bootloaders which support
+# FIT images). See doc/uImage.FIT/howto.txt in U-Boot source code for
+# additional information on FIT images.
