From: Marian Balakowicz Date: Wed, 12 Mar 2008 09:35:46 +0000 (+0100) Subject: [new uImage] Add proper ramdisk/FDT handling when FIT configuration is used X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f773bea8e11f4a11c388dcee956b2444203e6b65;p=project%2Fbcm63xx%2Fu-boot.git [new uImage] Add proper ramdisk/FDT handling when FIT configuration is used Save FIT configuration provied in the first bootm argument and use it when to get ramdisk/FDT subimages when second and third (ramdisk/FDT) arguments are not specified.
