所用的开发板上带了一片DM9000的网络芯片，这个芯片的驱动在uclinux中自带了，所需要做的就是将它的资源添加到arch\blackfin\mach-bf561\boards\ezkit.c中。

首先添加资源定义：

static struct resource dm9000_bfin_resources[] = {

{

.start = 0x2C000000,

.end = 0x2C000000 + 0x7F,

.flags = IORESOURCE_MEM,

}, {

.start = IRQ_PF10,

.end = IRQ_PF10,

.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_LOWLEVEL,

},

};

static struct platform_device dm9000_bfin_device = {

.name = "dm9000",

.id = -1,

.num_resources = ARRAY_SIZE(dm9000_bfin_resources),

.resource = dm9000_bfin_resources,

};

然后修改ezkit_devices的定义：

static struct platform_device *ezkit_devices[] __initdata = {

…………………………………..

&dm9000_bfin_device,

…………………………………..

};

在工程中加上net目录下的相关文件，编译运行，在启动信息中多了以下几行：

NET: Registered protocol family 16
