u-boot烧写yaffs2文件系统
以前移植的U-boot一直都支持Yaffs2文件系统的烧写，但是我一直都没有时间测试，其中的Bug也是网友发现后修正的。虽然现在又有新的UBI文件系统，但是UBI是在Linux2.6.28以后才被支持的，所以yaffs2还是需要的。前几天因为项目需要，我又试了一次Yaffs2的烧写引导，在这里记录下来，以备后用。
一、下载Yaffs2映像制作工具。
mkyaffs2image就在yaffs2的源码包里：Yaffs源码下载
下载源码解压之后，在utils文件夹下的两个C文件就是yaffs和yaffs2文件映像制作工具，这里只将yaffs2了。512B/page的nand已经比较少了。
二、打上补丁
为了正确制作Yaffs2文件系统映像，必须打上一下补丁：
将补丁拷贝到Yaffs2源码目录下，并执行：
补丁参考：http://www.100ask.net/showtopic-2011.aspx
这个补丁增加了oob的两字节偏移和oob中ECC的产生。否则新的内核和yaffs2文件系统挂载会出错。
由于大小端的转换还有问题，所以被我去掉了。
三、编译
直接在utils目录下“make”就可以了。
四、制作yaffs2映像文件
制作命令很简单：
五、用U-boot烧入nand flash。
添加yaffs2烧写功能的补丁是没有硬件依赖的，不单单在2440上可以用，应该可以说是在被Uboot支持的、可以操作Nand Flash中的oob的CPU上应该都可以用。我在别的CPU上已做了实验，没有问题。
yaffs2烧写功能的补丁：
要烧写的位置和内核分区有关。先擦除后烧写。
六、更新内核启动参数，并启动测试。

四、制作yaffs2映像文件
制作命令很简单：
mkyaffs2image [dir] [image_file_name] |
[dir]：是你要制做的文件系统内容所在的目录
[image_file_name] ： 是生成的映像名。
