From addb2e1650fdf872334478393f482dfdce965a61 Mon Sep 17 00:00:00 2001
From: Bartlomiej Sieka <tur@semihalf.com>
Date: Sun, 5 Mar 2006 18:57:33 +0100
Subject: [PATCH] Re-factoring the legacy NAND code (legacy NAND now only in
 board-specific code and in SoC code). Boards using the old way have
 CFG_NAND_LEGACY and BOARDLIBS = drivers/nand_legacy/libnand_legacy.a added.
 Build breakage for NETTA.ERR and NETTA_ISDN - will go away when the new NAND
 support is implemented for these boards.

- *  Changelog:
- *   01-31-2000 DMW     Created
- *   09-18-2000 SJH     Moved structure out of the Disk-On-Chip drivers
- *			so it can be used by other NAND flash device
- *			drivers. I also changed the copyright since none
- *			of the original contents of this file are specific
- *			to DoC devices. David can whack me with a baseball
- *			bat later if I did something naughty.

- *			hardwarespecific function for accessing control lines
- *   02-21-2002 TG	added support for different read/write adress and
- *			ready/busy line access function
- *   02-26-2002 TG	added chip_delay to nand_chip structure to optimize
- *			command delay times for different chips
- *   04-28-2002 TG	OOB config defines moved from nand.c to avoid duplicate
- *			defines in jffs2/wbuf.c
- *   08-07-2002 TG	forced bad block location to byte 5 of OOB, even if
- *			CONFIG_MTD_NAND_ECC_JFFS2 is not set
- *   08-10-2002 TG	extensions to nand_chip structure to support HW-ECC
- *
- *   08-29-2002 tglx 	nand_chip structure: data_poi for selecting
- *			internal / fs-driver buffer
- *			support for 6byte/512byte hardware ECC
- *			read_ecc, write_ecc extended for different oob-layout
- *			oob layout selections: NAND_NONE_OOB, NAND_JFFS2_OOB,
- *			NAND_YAFFS_OOB
- *  11-25-2002 tglx	Added Manufacturer code FUJITSU, NATIONAL
- *			Split manufacturer and device ID structures
- *
- *  02-08-2004 tglx 	added option field to nand structure for chip anomalities
