From d5934ad7756f038a393a9cfab76a4fe306d9d930 Mon Sep 17 00:00:00 2001 From: Marian Balakowicz Date: Mon, 4 Feb 2008 08:28:09 +0100 Subject: [new uImage] Add dual format uImage support framework This patch adds framework for dual format images. Format detection is added and the bootm controll flow is updated to include cases for new FIT format uImages. When the legacy (image_header based) format is detected appropriate legacy specific handling is invoked. For the new (FIT based) format uImages dual boot framework has a minial support, that will only print out a corresponding debug messages. Implementation of the FIT specific handling will be added in following patches.
