第一步，配置内核
<*>Memory Technology Device (MTD) support --->
[*] MTD partitioning support
<*> NAND Device Support --->
<*> NAND Flash support for Samsung S3C SoCs
<*> Support for generic platform NAND driver
第二步：配置资源，添加以下代码
（1）头文件
#include <linux/mtd/nand.h>
#include <linux/mtd/partitions.h>
#include <linux/mtd/physmap.h>
#include <linux/mtd/partitions.h>
#include <plat/nand.h>
（2）配置信息
#define SZ_1K 0x00000400
#define SZ_1M 0x00100000
/* NAND flash controller */
#define S3C64XX_PA_NAND (0x70200000)
#define S3C64XX_SZ_NAND SZ_1M
struct mtd_partition s3c_partition_info[] ={
{
.name = "Bootloader",
.offset = 0,
.size = (4 * 128 *SZ_1K),
.mask_flags = MTD_CAP_NANDFLASH,
},
{
.name = "Kernel",
.offset = (4 * 128 *SZ_1K),
.size = (5*SZ_1M) ,
.mask_flags = MTD_CAP_NANDFLASH,
},
{
.name = "File System",
.offset = MTDPART_OFS_APPEND,
.size = MTDPART_SIZ_FULL,
}
};
static struct s3c2410_nand_sets3c6410_nand_sets[] = {
[0]= {
.name = "nand",
.nr_chips = 1,
.nr_partitions = ARRAY_SIZE(s3c_partition_info),
.partitions = s3c_partition_info,
},
};
static struct s3c2410_platform_nands3c6410_nand_info = {
.tacls = 25,
.twrph0 = 55,
.twrph1 = 40,
.nr_sets = ARRAY_SIZE(s3c6410_nand_sets),
.sets = s3c6410_nand_sets,
};
（3）注册nandflah设备
1.在static void __init smdk6410_machine_init(void)函数中添加以下代码
s3c_nand_set_platdata(&s3c6410_nand_info);
2.添加平台设备
static struct platform_device*anw6410_devices[] __initdata = {
&s3c_device_fb,
&anw6410_lcd_powerdev,
&anw6410_device_eth,
//新添加
&s3c_device_nand,
};
