s3c6410(arm11核)的nandflash移植
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,
};
