Subject: [PATCH 08/34] ARM OMAP boards: switch to barebox_arm_entry
Date: Sun, 27 Jan 2013 11:46:37 +0100	[thread overview]
Message-ID: <1359283623-1782-9-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1359283623-1782-1-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.
