Subject: [PATCH 05/11] armlinux: reorder tag setup
Date: Thu, 24 Jun 2010 11:39:10 +0200	[thread overview]
Message-ID: <1277372356-32370-6-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1277372356-32370-1-git-send-email-s.hauer@pengutronix.de>

We call the individual setup_*_tag functions from three different
boot commands. Waste less space by calling a single setup_tags function
instead.
