废话不说了，就讲讲要怎么改，
（1）arch/arm/mach-s3c2410/common-smdk.c
static struct s3c2410_platform_nand smdk_nand_info = {
.tacls = 0,
.twrph0 = 30,
.twrph1 = 0,
.nr_sets = ARRAY_SIZE(smdk_nand_sets),
.sets = smdk_nand_sets,
};
（2）arch/arm/mach-s3c2410/mach-smdk2410.c
static struct map_desc smdk2410_iodesc[] __initdata = {
/* nothing here yet */
/* Map the ethernet controller CS8900A */
{ 0xe0000000, __phys_to_pfn(S3C2410_CS3+0x01000000), SZ_1M, MT_DEVICE }
};
static struct resource cs89x0_resources[] = {drivers/net/cs89x0.c
[0] = {
.start = 0x19000000,
.end = 0x19000000 + 16,
.flags = IORESOURCE_MEM,
},
[1] = {
.start = IRQ_EINT9,
.end = IRQ_EINT9,
.flags = IORESOURCE_IRQ,
},
};
static struct platform_device cs89x0_device = {
.name = "cirrus-cs89x0",
.num_resources = ARRAY_SIZE(cs89x0_resources),
.resource = cs89x0_resources,
};
static struct platform_device *smdk2410_devices[] __initdata = {
&s3c_device_usb,
&s3c_device_lcd,
&s3c_device_wdt,
&s3c_device_i2c,
&s3c_device_iis,
&cs89x0_device,
};
（3）添加对cs8900网卡的支持
主要看patch

（4）还有添加对devfs的支持，网上资料一大堆，我就不多说了。
（5) 推荐用3.4.1版本的编译器编译。
（6）网上有很多资料多说要去掉mtd对nand的ecc检测，但是经过我的测试，这样做会有很多问题。特别是使用yaffs文件系统，就应该关掉yaffs自带的ecc,而用mtd的ecc。
（7)yaffs的移植，我后面再说。
