## OK6410--DM9000网卡驱动移植： ##

在linux的内核中已经带有了DM9000的网卡驱动，所以网卡驱动我们不需要再去写或者移植了，只需要添加一个平台信息就可以。

首先在linux-3.3.5/arch/arm/mach-s3c64xx/mach-ok6410.c里面添加都文件\#include <linux/dm9000.h>

在linux-3.3.5/arch/arm/mach-s3c64xx/mach-ok6410.c里面添加dm9000的平台信息：

#define S3C64XX_PA_DM9000    (0x18000000)
    #define S3C64XX_SZ_DM9000    SZ_1M
    static struct resource ok6410_dm9000_resources[] = {
        [0] = {
        	.start= S3C64XX_PA_DM9000,
        	.end= S3C64XX_PA_DM9000 + 3,
        	.flags= IORESOURCE_MEM,
        },
        [1] = {
        	.start= S3C64XX_PA_DM9000 + 4,
        	.end= S3C64XX_PA_DM9000 + S3C64XX_SZ_DM9000 - 1,
        	.flags= IORESOURCE_MEM,
        },
        [2] = {
        	.start= IRQ_EINT(7),
        	.end= IRQ_EINT(7),
        	.flags= IORESOURCE_IRQ | IRQF_TRIGGER_HIGH,
        },
    };
    
    static struct dm9000_plat_data ok6410_dm9000_platdata = {
    	.flags= DM9000_PLATF_16BITONLY,
    	.dev_addr= { 0x08, 0x90, 0x00, 0xa0, 0x90, 0x90 },
    };
    
    static struct platform_device ok6410_device_dm9000 = {
    	.name= "dm9000",
    	.id= 0,
    	.num_resources= ARRAY_SIZE(ok6410_dm9000_resources),
    	.resource= ok6410_dm9000_resources,
    	.dev= {
    	.platform_data = &ok6410_dm9000_platdata,
    	}
    };

然后在

然后在static struct platform\_device \*ok6410\_devices\[\] \_\_initdata =里面添加

&ok6410_device_dm9000,

因为我们是直接复制已有的板极文件，所有有些驱动的资源会发生冲突，为了避免资源的冲突发生我们屏蔽掉

//&ok6410_smsc911x,

配置如上。

进行make uImage

下载内核到开发板会如果出现了下面红字部分则表明网卡启动成功了
