Subject: [PATCH 10/16] ARM bootm: only use concatenated oftree when no other is available
Date: Fri, 11 Jan 2013 14:24:30 +0100	[thread overview]
Message-ID: <1357910676-4231-11-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1357910676-4231-1-git-send-email-s.hauer@pengutronix.de>

When an oftree is already specified use it. This lets the user
boot a kernel with an oftree he provided himself rather than
hardcoding the concatenated one.
