# 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.
