--------------------------------------------------------------------------------------------------------------------------------
1、修改arch/arm/mach-s3c2440/mach-smdk2440.c
#include<linux/dm9000.h> //添加dm9000頭文件
在設備結構體中添加dm9000網卡
static struct platform_device *smdk2440_devices[] __initdata = {
&s3c_device_ohci,
&s3c_device_lcd,
&s3c_device_wdt,
&s3c_device_i2c0,
&s3c_device_iis,
&s3c_device_rtc,
&s3c_device_dm9000,
};
添加如下代碼：
/*DM9k ethernet driver info,add by Lu Zengmeng,2015-11-25*/
#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,
},
};
/*End of DM9K*/
2、配置menuconfig，使能DM9000相關驅動

重新編譯內核後燒錄到開發板上測試
