Subject: [PATCH 04/12] imx_nand: use memcpy for copying from/to buffer
Date: Mon, 29 Mar 2010 11:36:15 +0200 [thread overview]
Message-ID: <1269855383-22716-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1269855383-22716-1-git-send-email-s.hauer@pengutronix.de>
We do not need to use memcpy32 in read_buf/write_buf because
in these functions we only access SDRAM and not the internal SRAM
buffer.
