Sorry, I should have looked at the archives. This makes it all clear to me.

I have spoken to David about this and I am more than happy to provide the 
source to anyone. David, kindly, suggested I send the code to him and he 
would have a look before integrating it into the CVS system. I have not sent 
it to David as there are restrictions which would not make it suitable for 
all. I had planned to remove these and tidy things up but I just have not 
made the time.

I guess JFFS2 and YAFFS will not bothered about my NAND driver doing auto 
placement as they have their own schemes ?

As I said, I will supply you the code but I do not expect you to support it
and I do regard it as, incomplete, for gereral use.

Thomas, 

Thankyou for your support, again :-). At some time I will look into how I can 
change the SSFDC layer to interface properly to mtd/nand. As my frig seems to 
work for now I am inclined to go with it, unless you think this otherwise.

Cheers 

Simon.
