Subject: [PATCH 10/12] ARM: i.MX53 Vincell: Add NAND xload support
Date: Wed, 14 Sep 2016 11:12:46 +0200	[thread overview]
Message-ID: <1473844368-13030-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1473844368-13030-1-git-send-email-s.hauer@pengutronix.de>

The Vincell boards do the SDRAM setup from board init code, so the
image size is limited to the internal SRAM size. To overcome this
limitation use the NAND xload support.
