还以为用repo拖下来的代码中已经含有S3C6410处理器，结果让我失望，没有！
没有办法，只有自己移植一下，还好前面做过锻炼，问题不大。
友坚开发板附带的是android-0.09，但是Linux内核却是最新的2.6.29，难道是在2.6.29内核中打的android补丁？
那就从2.6.29中将6410的内容搬运到android-1.5-cupcake（基于2.6.27内核）中吧。
==================================================================================
编译前的准备工作：
将arch/arm/目录下的mach-6400 mach-6410 plat-s3c64xx plat-s3c都复制过去，如果有相同的覆盖处理
同理，include/asm-arm目录也同样覆盖
按照29内核修改27内核中arch/arm目录的Kconfig和Makefile文件
内核选中S3C64XX及smdk6410开发板，开始make
(1)找不到头文件
