还是先来吐槽：本来我是在上一个星期的周末已经把 Linux2.6.34.11 的驱动已经成功的移植到， OK6410 的开发板上的，并且能够启动主机上的NFS 根文件系统， 可是我在周一的时候，开始学习LCD 的驱动程序， 在修改内核文件的时候，有几处错误修改，将原来自己做的2.6.34.11 的内核源码 搞的乱七八糟的，在这里还是自己在修改内核的时候没有提注重注释， 并且没有记录下来自己的操作步骤，以至于我没办法，恢复2.6.34 的内核， 所以也就只能重新先开始最基础的内核移植了。 这次我选择的是2.6.36.2 的内核， 谁知到一开始移植就出现一大堆问题。在这里我不得不说，飞凌开发人员对内核修改的代码，管理真的是太扯了，自己在注销任何一个设备是没有一点点注释，就把这个设备原有的线性地址分配给其它设备了，让我让我们这些菜鸟干看着一大堆的报错信息顶个什么用， 真的是伤不起。好了不乱扯了，现在开始记录。
我的开发环境是：
VMware Ubuntu 10.10 。OK6410 A版 256M+2G 的开发板。 主机系统：XP。Uboot：飞凌提供的Uboot。
参考内核 ：飞凌提供的 Forlinx 的2.6.36.2 内核
操作步骤 以下./ 均代表你的内核 根目录
1、修改./Makefile191 ARCH ?=arm // 指定cpu类型， arm后面不要有空格，要不然编译是会提醒ARCH 不能为一个目录
192 CROSS_COMPILE ?=/usr/local/arm/4.2.2-eabi/usr/bin/arm-linux- // 指定交叉编译器的路径,按照你自己的进行指定路径2、修改./arch/arm/mach-s3c64xx/mach-smdk6410.c 1） nandflash 驱动，修改方法
加载头文件
#include <linux/mtd/mtd.h>
#include <linux/mtd/partitions.h>
#include <plat/nand.h> //这些头文件放在./arch/arm/plat-samsung/include/ 下面
添加nand 结构体
// add by acanoe first
externvoid s3c64xx_reserve_bootmem(void); //add by acanoe
struct mtd_partition ok6410_nand_part[] = {
{
.name = "Bootloader",
.offset = 0,
.size = (1 * SZ_1M),
.mask_flags = MTD_CAP_NANDFLASH,
},
{
.name = "Kernel",
.offset = (1 * SZ_1M),
.size = (5*SZ_1M) ,
.mask_flags = MTD_CAP_NANDFLASH,
},
{
.name = "User",
.offset = (6 * SZ_1M),
.size = (120*SZ_1M) ,
},
{
.name = "File System",
.offset = MTDPART_OFS_APPEND,
.size = MTDPART_SIZ_FULL,
}
};
staticstruct s3c2410_nand_set ok6410_nand_sets[] = {
[0] = {
.name = "nand",
.nr_chips = 1,
.nr_partitions = ARRAY_SIZE(ok6410_nand_part),
.partitions = ok6410_nand_part,
},
};
staticstruct s3c2410_platform_nand ok6410_nand_info = {
.tacls = 25,
.twrph0 = 55,
.twrph1 = 40,
.nr_sets = ARRAY_SIZE(ok6410_nand_sets),
.sets = ok6410_nand_sets,
};
//add by acanoe first
修改
对照这个结构体 将那些进行修改，注意 by acanoe 的语句为修改重点。
staticstruct platform_device *smdk6410_devices[] __initdata = {
//#ifdef CONFIG_SMDK6410_SD_CH0 //<span >Canceled</span> by acanoe
&s3c_device_hsmmc0,
//#endif //<span >Canceled</span> by acanoe
//#ifdef CONFIG_SMDK6410_SD_CH1 //<span >Canceled</span> by acanoe
&s3c_device_hsmmc1,
//#endif //<span >Canceled</span> by acanoe
&s3c_device_i2c0,
// &s3c_device_i2c1, //<span >Canceled</span> by acanoe
&s3c_device_fb,
&s3c_device_ohci,
&s3c_device_usb_hsotg,
// &s3c64xx_device_iisv4, //<span >Canceled</span> by acanoe
// &samsung_device_keypad, //<span >Canceled</span> by acanoe
// add by acanoe 2
&s3c_device_nand,
#ifdef CONFIG_DM9000
&s3c_device_dm9000,
#endif
// add by acanoe 2
#ifdef CONFIG_REGULATOR
&smdk6410_b_pwr_5v,
#endif
&smdk6410_lcd_powerdev,
// &smdk6410_smsc911x, // <span >Canceled</span> by acanoe
&s3c_device_adc,
// &s3c_device_cfcon, // <span >Canceled</span> by acanoe
&s3c_device_rtc,
// &s3c_device_ts, // <span >Canceled</span> by acanoe
// &s3c_device_wdt,
};
对照这个结构体 将那些进行修改，注意 by acanoe 的语句为修改重点。
// add by acanoe 2
&s3c_device_nand, //这一语句为添加nand 设备语句
#ifdef CONFIG_DM9000
&s3c_device_dm9000, //这一句为添加dm9000 网卡设备驱动语句。
#endif
// &smdk6410_smsc911x, // <span >Canceled</span> by acanoe 这一项一定要注销掉， 后面我会讲为什么。
//在smdk6410_machine_init() 结构体中加上
//add by acanoe
s3c_nand_set_platdata(&ok6410_nand_info);
//add by acanoe
3、copy ./include copynfig copy ./arch/arm/plat-samsung/include
这三项都是指： 从飞凌提供的内核将 他们的include 库拷贝的你的内核当中 ，拿来主义。
这样做的有点是你可以只先学习驱动移植 ，和系统移植的方法，而不是其语句的实现。确定也是优点的相对。
在这里极有可能会因为你include 的更新而产生一些写的错误 如在飞凌自定义的 _ts_ 中也就是 触摸屏的去的是他们自己修改的。
可能会因此报错，解决办法，就是Canceled 掉 所有的 有关触摸屏的驱动，都注释掉。
其实到这里，如果内不是要NFS 挂载根文件系统的话，内核移植工作已经完成。
不过这只针对飞凌的开发板来说， 如果你是其他厂家的开发板，在下面的几个知识点，不得不提及一下：
3.1)给内核打上yaffs2 文件系统补丁，在这里尽量选用较新的补丁，因为旧版补丁，在编译的时候会报错，
下载连接;a=summary，直接点击，点那个2011年6月28号的那个版本，点击最右边的SNAPSHOT下载，这个是目前较新的的YAFFS2的源码了
3.2) 修改机器号，这一步飞凌的开发板并不用操作，因为飞凌的Uboot 和内核都默认使用 smdk6410 ，的ID 来进行参数传递（典型的修改注意）。机器号修改依赖文件目录：
uboot-2011.3机器码路径：
arch/arm/include/asm/mach-types.h
飞凌体统的Uboot为 旧版的Uboot 它的 机器码定义路径为：
include/asm-arm/mach-types.h
其中 smdk6410 的自己码被定义在 include/configs/smdk6410.h 定义为
#define MACH_TYPE 1626
2.6.36.2 内核机器码定义路径为 arch/arm/tools/mach-types
smdky410 MACH_SMDK6410 SMDK6410 1626
以上 U-boot 和 内核 ID 信息 都属于smdk6410 板载 默认信息不用修改。
3.3) 配置内核， make menuconfig
因为直接copy 飞凌源码nfig 文件到自己的根目录，所以配置起来比较简单。只要注意nand flash 驱动是否被选中即可：
Device Drivers --->
<*> Memory Techology Device (MTD) support --->
<*> NAND Device Support --->
<*> NAND Flash support for S3C SoC
二 、 加载dm9000 驱动。
4、加载dm9000驱动， 我自己更加喜欢NFS 挂载根文件系统 所以内核要移植dm9000 网卡的驱动。
copy drivers/net/dm9000 //copy 飞凌源码 到目标内核， 其实这一步可以不做，因为 dm9000 驱动为通用驱动，这里copy 也是没有必要。
4.1） 修改arch/arm/mach-s3c6410/mach-smdk6410.c
添加头文件 #incude <linux/dm9000.h>
添加dm9000 结构体。
//add by acanoe dm9000
/* Ethernet */
#define S3C64XX_PA_DM9000 (0x18000000)
#define S3C64XX_SZ_DM9000 SZ_1M
#define S3C64XX_VA_DM9000 S3C_ADDR(0x03b00300)
staticstruct resource 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,
},
};
staticstruct dm9000_plat_data dm9000_setup = {
.flags = DM9000_PLATF_16BITONLY,
.dev_addr = { 0x08, 0x90, 0x00, 0xa0, 0x90, 0x90 },
};
staticstruct platform_device s3c_device_dm9000 = {
.name = "dm9000",
.id = 0,
.num_resources = ARRAY_SIZE(dm9000_resources),
.resource = dm9000_resources,
.dev = {
.platform_data = &dm9000_setup,
}
};
//#ifdef CONFIG_DM9000
//add by acanoe dm9000
在
staticstruct platform_device *smdk6410_devices[] __initdata = {
#ifdef CONFIG_DM9000
&s3c_device_dm9000, // dm9000 driver add by acanoe
#endif
// add by acanoe 2
// &smdk6410_smsc911x, // Canceled by acanoe 对于OK6410 的网卡实验来说，这一项一定要注视掉。
};
4.2）下来我来讲讲为什么要进行上面的修改。
因为内核本身是支持dm9000 的，所以我们要做的就是告诉内核，我添加了这个设备了，并且添加他的物理地址。
#define S3C64XX_PA_DM9000 (0x18000000)
#define S3C64XX_SZ_DM9000 SZ_1M
#define S3C64XX_VA_DM9000 S3C_ADDR(0x03b00300)
这一个语句的意思就是 DM9000 设备的物理地址为0x18000000， 大小为1M ， 虚拟地址为0x03b00300
而当我做了N多便还是错，报错信息为：
NET: Registered protocol family 16
smsc911x: failed to claim resource 0
------------[ cut here ]------------
WARNING: at drivers/base/core.c:130 device_release+0x80/0x8c()
Device 'platform-lcd.0' does not have a release() function, it is broken and must be fixed.

[<c0035b9c>] (dump_stack+0x18/0x1c) from [<c004bfec>] (warn_slowpath_common+0x58/0x70)
我总以为是 nand flash 的信息错了，其实不是。
在我排查DM9000 驱动的时候，我注意到DM9000 分配的物理地址还被分配到了另一设备，就是 smdk6410_smsc911x 这个设备
它在 arch/arm/mach-s3c64xx/include/mach/map.h 被这样定义
#define S3C64XX_PA_XM0CSN1 (18000000)
这个错误让我找了好久，好久，为了找到这个错误，我编译过的内核不下5个不同的版本，编译的次数不下30 次，
原因就是自己太菜，并且飞凌在使用这些已经被定义的 设备资源的时候，竟然在代码中没有丝毫的注释，真是整人啊。
到这里，编译内核，（注意要加载DM9000 驱动支持） 下载到开发板上就可以启动你的NFS 根文件系统了。
下面是我启动内核的全部打印信息，你可以对照着参考一下:
