From mboxrd@z Thu Jan 1 00:00:00 1970 From: =?utf-8?Q?Beno=C3=AEt_Th=C3=A9baudeau?= Date: Mon, 13 Aug 2012 22:49:42 +0200 (CEST) Subject: [U-Boot] [PATCH 06/13] mxc nand: Access all ecc_status_result fields In-Reply-To: <1580773374.2374979.1344890876408.JavaMail.root@advansee.com> Message-ID: <1372434962.2374989.1344890982845.JavaMail.root@advansee.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de On the NFC IP 1.1, the 32-bit ecc_status_result value comes from 2 consecutive 16-bit registers. This patch reads all the fields of this value, which makes a difference for 4-kiB NF pages.
