(reported by Ruben):

Yaffs2 give big issues as ard mentioned in the kernel sources we 
have patched so far based v33/34 from linuxtogo.org  
Our current kernel will mess-up our nands.. oeps.

The yaffs2 stuff from qi-hardware is already patched to work in a 
better way.

qi hardware sources (trunk v809) 
svn co 
http://projects.qi-hardware.com/svn/ingenic-linux-02os-linux-2-6-24-3
/trunk
 
- copying the /include/linux/ and /fs/yaffs2 stuff to our sources. 
(I did not copy mtd.h otherwise I had some compiling errors)
- Needed to add some things to the yaffs2 setup in xconfig. Or just 
make oldconfig did add them by default.
- Afterwards yaffs2 and yaffs from nand works.
