part del kernel
part del root
part add kernel 0x00100000 0x00300000 0 SZ_1M*3

2，修改Makefile
ARCH = arm
CROSS_COMPILE = /usr/local/arm/3.4.1/bin/arm-linux-

第二步：修改nand flash的参数：
在同一个文件中找到
smdk_nand_info = {
.tacls=20,
.twrph0=60,
.twrph1=20,
...
}
改成
smdk_nand_info = {
.tacls=0,
.twrph0=30,
.twrph1=0,
...
}
___________________________
vi drivers/mtd/nand/s3c2410.c
s3c2410_nand_init_chip()函数，将其中的
chip->ecc.mode=NAND_ECC_SOFT;
改成
chip->ecc.mode=NAND_ECC_NONE;
2440:
修改时钟
在arch/arm/mach-s3c2440/mach-smdk2440.c中修改smdk2440_map_io如下
static void __init smdk2440_map_io(void)
{
s3c24xx_init_io(smdk2440_iodesc, ARRAY_SIZE(smdk2440_iodesc));
s3c24xx_init_clocks(12000000);
s3c24xx_init_uarts(smdk2440_uartcfgs, ARRAY_SIZE(smdk2440_uartcfgs));
}
