1、修改内核代码

vim arch/arm/mach-s3c2440/mach-smdk2440.c#include <Linux/dm9000.h>  //添加DM9000网卡的头文件

并添加如下代码：

/*Add DM9000 ethernet drivers*/#define DM9000_BASE    (S3C2410_CS4 + 0x300)static struct resource s3c_dm9000_resource[] = {     [0] = {        .start = DM9000_BASE,        .end   = DM9000_BASE + 3,        .flags = IORESOURCE_MEM    },    [1] = {        .start = DM9000_BASE + 4,        .end   = DM9000_BASE + 7,        .flags = IORESOURCE_MEM    },    [2] = {        .start = IRQ_EINT7,        .end   = IRQ_EINT7,        .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHEDGE,    }};

/*         * The DM9000 has no eeprom, and it's MAC address is set by * the bootloader before starting the kernel. */static struct dm9000_plat_data s3c_dm9000_pdata = {    .flags      = (DM9000_PLATF_16BITONLY | DM9000_PLATF_NO_EEPROM),};static struct platform_device s3c_device_dm9000 = {    .name       = "dm9000",    .id     = -1,    .num_resources  = ARRAY_SIZE(s3c_dm9000_resource),    .resource   = s3c_dm9000_resource,    .dev        = {        .platform_data  = &s3c_dm9000_pdata,    },};

2、在platform_device *smdk2440_devices[] __initdata结构体添加启动DM9000

static struct platform_device *smdk2440_devices[] __initdata = {    &s3c_device_ohci,    &s3c_device_lcd,    &s3c_device_wdt,    &s3c_device_i2c0,    &s3c_device_iis,    &s3c_device_dm9000,};

3、在dm9000.h下添加头文件

vim include/linux/dm9000.h#include <linux/io.h>

重新make编译内核，我们得内核就能DM9000网卡了。
