Yes, you most definitely can use YAFFS as a root file system on NAND. YAFFS 
also includes a very simple bootloader. There are also tools for generating a 
YAFFS file system image. Many people are using these with great success. Nick 
Bane wrote a mini-HOWTO  about how to add YAFFS to the kernel as the root 
file system.

The best place to start is to get the code from YAFFS CVS 
(http://www.aleph1.co.uk) . I suggest you also subscribe to the yaffs 
discussion list.
