移植最简单linux-3.5.4内核到s3c6410

1，下载最新的内核

2，将 arch/arm/mach-s3c64xx/下的,mach-smdk6410.c cp为 mach-my6410.c; 修改里面的内容

MACHINE_END

3，打开arch/arm/mach-s3c64xx/下的Kconfig，仿照 MACH_SMDK6410 做一个菜单项：

config MACH_MY6410
	bool "MY6410"
	select CPU_S3C6410
	help
	  Machine support for the CoreWind MY6410

4，打开arch/arm/mach-s3c64xx/下的makefile，添加

obj-$(CONFIG_MACH_MY6410) += mach-my6410.o

5. 打开 arch/arm/tools/mach-types文件，这里面存的是机器 ID必须要和,uboot 里面的ID 保持一致，将其283行复制添加在后面并修改为： 
smdk6410    MACH_SMDK6410   SMDK6410    1626 
xx6410    MACH_XX6410    XX6410    1626 这个机器ID和UBOOT 里的机
器ID相同时才能启动内核； 

5.    修改顶层的 Makefile： 
  ARCH ?= arm 
  CROSS_COMPILE ?= arm-linux- 
6. 复制 arch/arm/configs/下的s3c6400-defconfig 文件，然后将其保存为.config；

7，配置内核

现在下下载一个库

sudo apt-get install ncurses-dev 

s3c6400里面内核已经配置已经够好了，这里只需要把板子改成自己的板子

然后再在General setup下添加交叉编译器

8，把u-boot源码tools目录下的mkimage拷贝到/user/bin目录下

执行 make uImage

生成的uIamge在arm/arrn/boot下

9，然后再板子的u-boot模式下执行tftp c0008000 uImage至于怎么搭建tftp就要看我之前的文章了

启动信息如下：
