定义芯片信息

struct s3c2410_nand_set {
unsigned int disable_ecc:1;
unsigned int flash_bbt:1;

unsigned int options;
int nr_chips;
int nr_partitions;
char *name;
int *nr_map;
struct mtd_partition *partitions;
struct nand_ecclayout *ecc_layout;
};
/***对于NANDFLASH作为平台设备的一些时序信息等
struct s3c2410_platform_nand {
/* timing information for controller, all times in nanoseconds */

int tacls; /* time for active CLE/ALE to nWE/nOE */
int twrph0; /* active time for nWE/nOE */
int twrph1; /* time for release CLE/ALE from nWE/nOE inactive */

unsigned int ignore_unset_ecc:1;

int nr_sets;
struct s3c2410_nand_set *sets;

void (*select_chip)(struct s3c2410_nand_set *,
int chip);
};

/**********************************************************************************

static struct s3c2410_platform_nand eilian6410_nand_info = {
.tacls = 25,
.twrph0 = 55,
.twrph1 = 40,
.nr_sets = ARRAY_SIZE(eilian6410_nand_sets),
.sets = eilian6410_nand_sets,
};
/************************************************

该代码放在static struct platform_device *eilian6410_devices[] __initdata = {上面就行

同时记得添加如下头文件
