Yeah, I've created files, directories, removed them, change file content, etc.

There are still some issues to fix though - for example:
 * I don't understand how YAFFS2 manages the lseek (beyond the current
file size) + write.
 * I have an issue with fsync (can't remember what exactly, I had no
spare time to work on this port for a while)

I also need to update the port with the latest YAFFS2 code, as I think
one of the major issue I had was about loosing some data after a write
+ umount + mount command sequence.

I'll try to clean it up and post it on a public web site in the next few days.
