[Yaffs] Does yaffs support mux one nand?

Hi all,

On MTD website there was a comment saying that it does and if it doesn't then
referred some link, but unfortunately that link is broken.
I'd like to know does yaffs support mux one nand or not.
Can some one plz let me know the answer along with any info which can be useful
while adding support for mux-one-nand with mtd-yaffs2.

Advanced thanks for your help,
Venu
