Subject: [PATCH 04/14] bootm: use names instead of numbers for image parts
Date: Fri, 22 Jan 2016 08:32:22 +0100	[thread overview]
Message-ID: <1453447952-30818-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1453447952-30818-1-git-send-email-s.hauer@pengutronix.de>

The uImage format uses numbers for to identify the different
parts of a image, but the FIT image format uses names. To better
integrate the FIT image format into bootm always use names and
convert them to numbers when necessary.
