Subject: [PATCH 4/4] ARM: simplify start.c
Date: Fri, 5 Oct 2012 18:45:05 +0200 [thread overview]
Message-ID: <1349455505-31731-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1349455505-31731-1-git-send-email-s.hauer@pengutronix.de>
start() for the PBL case is a duplicate of board_init_lowlevel_return().
Instead of duplicating it just call it.
