From 8e35bb07eb68e524804f2ef53dd18c7cec0b06fc Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 22 Feb 2016 22:55:51 -0700 Subject: mkimage: Support automatic creating of a FIT without a .its At present, when generating a FIT, mkimage requires a .its file containing the structure of the FIT and referring to the images to be included. Creating the .its file is a separate step that makes it harder to use FIT. This is not required for creating legacy images. Often the FIT is pretty standard, consisting of an OS image, some device tree files and a single configuration. We can handle this case automatically and avoid needing a .its file at all. To start with, support automatically generate the FIT using a new '-f auto' option. Initially this only supports adding a single image (e.g. a linux kernel) and a single configuration.
