Subject: [PATCH 4/4] bootm: print Kernel commandline in verbose mode
Date: Thu, 30 May 2013 12:44:54 +0200	[thread overview]
Message-ID: <1369910694-20991-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1369910694-20991-1-git-send-email-s.hauer@pengutronix.de>

Without devicetree support we print the Kernel commandline in
verbose mode. Do the same with devicetree boot aswell.
