-# Tree (FIT) format. The FIT format uses a device tree structure to

|
|
-# 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.
