2004-10-04   drh     Add NAND specific partition header file
2004-09-30   drh     Move partition functions out to partition specific file
2004-09-29   drh     Support for dynamic 8/16 bit use
2004-09-24   drh     Correct handling of block numbers by using variable
                     instead of #define
2004-08-26   drh     Conditionally compile out functions not needed by
                     boot loader.
2004-08-11   drh     Add support for turning ECC off when needed
2004-07-20    gr     Added multi-threading support.
2004-07-20   drh     Do not compile partition functions for boot_loader
                     Fix bug in mark_block_bad function.
2004-07-08   drh     Add support for Samsung K9K1216Q0C
2004-06-09   drh     Prevent 8/16 bit false detection
2004-05-18   drh     Make flash name string more generic to not confuse user
2004-03-08   dlb     Rename FS_NAND... to FLASH_NAND...
2004-04-02   drh     Change use of spare_byte to spare_unit except func name
2004-03-30   drh     Add macros to separate setting wait states from setting
                     ECC enable/disable state.
2004-03-26   drh     Use single common ops table for all devices.
                     Modify probe to fill in device structure.
2004-03-19   drh     Change partition manipulation function names.
                     Correct ordering of flash reset.
2004-02-23   drh     Move device specific function dispatch tables out of
                     device common file and put them here.
                     Correct handling of wait states setting.
                     Remove functions that merely returned constants as they
                     are replaced by generic functions in flash_nand_device.c.
2004-01-21   drh     Came from services/efs/fs_nand_samsung.c
