14 * struct s3c2410_nand_set - define a set of one or more nand chips
15 * @disable_ecc: Entirely disable ECC - Dangerous
16 * @flash_bbt: Openmoko u-boot can create a Bad Block Table
17 * Setting this flag will allow the kernel to
18 * look for it at boot time and also skip the NAND
19 * scan.
20 * @options: Default value to set into 'struct nand_chip' options.
21 * @nr_chips: Number of chips in this set
22 * @nr_partitions: Number of partitions pointed to by @partitions
23 * @name: Name of set (optional)
24 * @nr_map: Map for low-layer logical to physical chip numbers (option)
25 * @partitions: The mtd partition list
26 *
27 * define a set of one or more nand chips registered with an unique mtd. Also
28 * allows to pass flag to the underlying NAND layer. 'disable_ecc' will trigger
29 * a warning at boot time.
