Subject: [PATCH 1/4] ARM i.MX53: enable imx53_init_lowlevel for pbl
Date: Fri, 12 Oct 2012 18:52:51 +0200 [thread overview]
Message-ID: <1350060774-24779-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1350060774-24779-1-git-send-email-s.hauer@pengutronix.de>
The KARO Tx53 board in the revision 8030 has an instable SDRAM
setup. It works as long as the MMU is disabled, but the board
crashes at arbitrary places once the MMU gets enabled. So we
need the PLL setup early. Enable it for pbl.
