linaro Android4.0.4 for FS100 - dm9000移植

1. 平台代码修改

vim arch/arm/mach-s5pc100/mach-smdkc100.c

2. 添加需要的头文件

#if defined (CONFIG_DM9000)
        #include <linux/dm9000.h>
        #include <linux/irq.h>
        #endif

3. 平台设备添加

// CMD为低，读写地址寄存器， CMD为高，读写数据寄存器

// 访问dm9000内部寄存器时，先将cmd拉低，向dm9000寄存器里写地址，然后，将cmd拉高，读写dm9000数据寄存器里的数据

#if defined(CONFIG_DM9000)
        // MichaelTang add start
        static struct resource dm9000_resources[] = {
                [0] = {
                        .start = 0x88000000, // 地址线
                        .end = 0x88000000 + 0x4 - 1,
                        .flags = IORESOURCE_MEM,
                },
                [1] = {
                        .start = 0x88000000 + 0x4, // 数据线
                        .end = 0x88000000 + 0x8 - 1,
                        .flags = IORESOURCE_MEM,
                },
                [2] = {
                        .start = S5P_IRQ_VIC0(10),
                        .end = S5P_IRQ_VIC0(10),
                        .flags = IORESOURCE_IRQ | IRQ_TYPE_LEVEL_HIGH, //申请中断及触发方式
                },
        };

        static struct dm9000_plat_data s5pc100_dm9000_platdata = { // 设置网卡mac物理地址
                .flags = DM9000_PLATF_16BITONLY,
                .dev_addr[0] = 0x0,
                .dev_addr[1] = 0x0,
                .dev_addr[2] = 0x11,
                .dev_addr[3] = 0x22,
                .dev_addr[4] = 0x33,
                .dev_addr[5] = 0x44,
        };
        static struct platform_device s3c_device_dm9ks = { // 注册设备结构体
                .name = "dm9000",
                .id = -1,
                .num_resources = ARRAY_SIZE(dm9000_resources),
                .resource = dm9000_resources,
                .dev = {
                        .platform_data = &s5pc100_dm9000_platdata,
                }
        };
        // MichaelTang add end
        #endif

4. 将dm9000添加到平台设备列表中

添加位置： smdkc100_devices[]中

#if defined (CONFIG_DM9000)
        // Michaeltang add
        &s3c_device_dm9ks,
        // MichaelTang add end
        #endif

5. 配置内核

$ make menuconfig

6. 网络配置

将dm9000配置编译进内核，执行make zImage，拷贝到tftp目录中，通过tftp加载测试内核。
