- *   09-18-2000 SJH     Moved structure out of the Disk-On-Chip drivers
- *			so it can be used by other NAND flash device

- *   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
- *
