mini2440移植所有驱动到3.4.2内核详细解说

//移植dm9000网卡驱动到linux-3.4.2内核

//试验mini2440机器ID
set machid 7CF
boot
ifconfig eth0 192.168.31.203
mount -t nfs -o nolock,vers=2 192.168.31.202:/work/nfs_root/fs_mini_mdev_new /mnt
ls /mnt
//测试挂载成功

移植dm9000到linux-3.4.2
修改mach-smdk2440.c(位于arch/arm/mach-s3c24xx/mach-smdk2440.c)
(使它也支持内核自带的DM9000网卡驱动)
1)添加头文件

#include <linux/dm9000.h> 

2)添加全局变量:

#define MACH_SMDK2440_DM9K_BASE (S3C2410_CS4 + 0x300)
static struct resource smdk2440_dm9k_resource[] = {
[0] = {
.start = MACH_SMDK2440_DM9K_BASE,
.end = MACH_SMDK2440_DM9K_BASE + 3,
.flags = IORESOURCE_MEM
},
[1] = {
.start = MACH_SMDK2440_DM9K_BASE + 4,
.end = MACH_SMDK2440_DM9K_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 SMDK2440_dm9k_pdata = {
.flags = (DM9000_PLATF_16BITONLY | DM9000_PLATF_NO_EEPROM),
};

static struct platform_device smdk2440_device_eth = {
.name = "dm9000",
.id = -1,
.num_resources = ARRAY_SIZE(smdk2440_dm9k_resource),
.resource = smdk2440_dm9k_resource,
.dev = {
.platform_data = &SMDK2440_dm9k_pdata,
},
};

3)在smdk2440_devices[]数组下添加:

static struct platform_device *smdk2440_devices[] __initdata = {
&s3c_device_ohci,
&s3c_device_lcd,
&s3c_device_wdt,
&s3c_device_i2c0,
&s3c_device_iis,
&smdk2440_device_eth, //添加该句
};

然后编译烧写

mount -t nfs -o nolock,vers=2 192.168.31.202:/work/nfs_root/fs_mini_mdev_new /mnt
ls /mnt

//新建drivers_and_test_new目录
cd /work/
mkdir drivers_and_test_new
cd drivers_and_test_new/

cd /work/system/linux-3.4.2/drivers/net/ethernet/davicom/

将

obj-$(CONFIG_DM9000) += dm9000.o

改为

obj-$(CONFIG_DM9000) += dm9dev9000c.o
