From mboxrd@z Thu Jan 1 00:00:00 1970 From: Frank Mandarino Date: Wed, 06 Dec 2006 12:50:42 -0500 Subject: [U-Boot-Users] [PATCH] Add support for AT91RM9200 NAND (Smartmedia) controller Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The attached patch adds support for the AT91RM9200 NAND (Smartmedia) controller, allowing use of the U-Boot NAND commands on AT91RM9200-based boards which use NAND flash. It uses four CFG parameters: CFG_NAND_BASE - address of Smartmedia chip select (normally 0x40000000) CFG_NAND_AT91_CLE_BIT - address bit number used to set CLE signal CFG_NAND_AT91_ALE_BIT - address bit number used to set ALE signal CFG_NAND_CHIP_DELAY - command delay time in microseconds I have been using this code for almost a year with no problems on our custom AT91RM9200 board. I believe it would be useful for others as the popularity of NAND flash increases. Regards, ../fam -- Frank Mandarino fmandarino(a)endrelia.com Endrelia Technologies Inc.
