Subject: [PATCH 09/28] ARM OMAP boards: switch to barebox_arm_entry
Date: Wed, 17 Oct 2012 23:03:18 +0200	[thread overview]
Message-ID: <1350507817-7819-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1350507817-7819-1-git-send-email-s.hauer@pengutronix.de>

All boards use hardcoded SDRAM addresses, copied from the board init file.
OMAP3 boards are a bit special, they had a SoC specific reset() function. This
is renamed to omap3_invalidate_dcache() and called from the board lowlevel init
code now.
