Linux-2.6.32 在Mini2440上的移植（三）----移植yaffs2

本移植主要参考友善之臂移植手册完成，做个笔记以备不时之需
Linux-2.6.32 在Mini2440上的移植（三）
使用环境：fedora9
交叉编译工具链：arm-linux-gcc-4.4.3
内核源码来源：
内核存放目录：/opt/mymini2440/linux-2.6.32
说明：红色部分为代码修改部分

进入解压好的yasffs2目录，执行如下语句为内核打上yaffs补丁：
#./patch-ker.sh c /opt/mymini2440/linux-2.6.32/
配置Linux内核使其支持yaffs2文件系统：
#make menuconfig
File systems --> [*] Miscellaneous filesystems --> <*> YAFFS2 file system support 
编译内核：
#make zImage
在vivi菜单下，输入【k】将zImage下载到nandflash，输入【y】下载友善之臂自带文件系统到nandflash用以测试，输入【b】启动内核
