FL2440移植LINUX-3.4.2（五）-- 添加DM9000的支持
1.参考mini2440拷贝：
linux-3.4.2\arch\arm\mach-s3c24xx\mach-mini2440.c
里的
/* DM9000AEP 10/100 ethernet controller */
1 /* DM9000AEP 10/100 ethernet controller */
2
3 static struct resource mini2440_dm9k_resource[] = {
4 [0] = {
5 .start = MACH_MINI2440_DM9K_BASE,
6 .end = MACH_MINI2440_DM9K_BASE + 3,
7 .flags = IORESOURCE_MEM
8 },
9 [1] = {
10 .start = MACH_MINI2440_DM9K_BASE + 4,
11 .end = MACH_MINI2440_DM9K_BASE + 7,
12 .flags = IORESOURCE_MEM
13 },
14 [2] = {
15 .start = IRQ_EINT7,
16 .end = IRQ_EINT7,
17 .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHEDGE,
18 }
19 };
20
21 /*
22 * The DM9000 has no eeprom, and it's MAC address is set by
23 * the bootloader before starting the kernel.
24 */
25 static struct dm9000_plat_data mini2440_dm9k_pdata = {
26 .flags = (DM9000_PLATF_16BITONLY | DM9000_PLATF_NO_EEPROM),
27 };
28
29 static struct platform_device mini2440_device_eth = {
30 .name = "dm9000",
31 .id = -1,
32 .num_resources = ARRAY_SIZE(mini2440_dm9k_resource),
33 .resource = mini2440_dm9k_resource,
34 .dev = {
35 .platform_data = &mini2440_dm9k_pdata,
36 },
37 };
到linux-3.4.2\arch\arm\mach-s3c24xx\mach-smdk2440.c文件里面
2.修改为如下：
1 #include <linux/dm9000.h> /* by zhutao 添加头文件*/
2 #define MACH_SMDK2440_DM9K_BASE (S3C2410_CS4 + 0x300) /* by zhutao 添加宏定义*/
3
4 /* DM9000AEP 10/100 ethernet controller */

6 static struct resource smdk2440_dm9k_resource[] = {
7 [0] = {
8 .start = MACH_SMDK2440_DM9K_BASE,
9 .end = MACH_SMDK2440_DM9K_BASE + 3,
10 .flags = IORESOURCE_MEM
11 },
12 [1] = {
13 .start = MACH_SMDK2440_DM9K_BASE + 4,
14 .end = MACH_SMDK2440_DM9K_BASE + 7,
15 .flags = IORESOURCE_MEM
16 },
17 [2] = {
18 .start = IRQ_EINT7,
19 .end = IRQ_EINT7,
20 .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHEDGE,
21 }
22 };
23
24 /*
25 * The DM9000 has no eeprom, and it's MAC address is set by
26 * the bootloader before starting the kernel.
27 */
28 static struct dm9000_plat_data smdk2440_dm9k_pdata = {
29 .flags = (DM9000_PLATF_16BITONLY | DM9000_PLATF_NO_EEPROM),
30 };
31
32 static struct platform_device smdk2440_device_eth = {
33 .name = "dm9000",
34 .id = -1,
35 .num_resources = ARRAY_SIZE(smdk2440_dm9k_resource),
36 .resource = smdk2440_dm9k_resource,
37 .dev = {
38 .platform_data = &smdk2440_dm9k_pdata,
39 },
40 };
41
42 /* 增加平台设备 */
43 static struct platform_device *smdk2440_devices[] __initdata = {
44 &s3c_device_ohci,
45 &s3c_device_lcd,
46 &s3c_device_wdt,
47 &s3c_device_i2c0,
48 &s3c_device_iis,
49 &smdk2440_device_eth, /* by zhutao */
50 };
编译启动内核：
nfs挂接网络文件系统:
修改以下根文件系统inittab
1 #s3c2410_serial0::askfirst:-/bin/sh /* 注释掉 */
2 console::askfirst:-/bin/sh /* 改成console */
