Subject: [PATCH 18/34] ARM AT91: switch to barebox_arm_entry part1
Date: Fri,  1 Feb 2013 08:59:31 +0100	[thread overview]
Message-ID: <1359705587-9762-19-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1359705587-9762-1-git-send-email-s.hauer@pengutronix.de>

This switches the at91sam926x, 9g10 and 9g20 over to barebox_arm_entry.
For these SoCs we currently support reading back the memory size from
the SDRAM controller, so all of these can have a common reset() function.
