Well, it's on and off. It's not high priority for me, so there has not 
been much work lately.

Ok, I send you the patch for YAFFS1 support, as well as the patch for 
STM32 NAND support.

Concerning UFFS. I've done some prototyping and brainstorming to improve 
UFFS and make it a better fit for eCos. Ricky, the original developer 
takes my advices and incorporates them into newer releases. So, he's 
actually the guy doing most of the hard work. I think we will soon have 
a newer version which can be integrated into eCos. I'll do a port once 
UFFS is ready for.

Best regards
Simon
