[Yaffs] YAFFS support for 16bit NAND flash

I'm currently try to evaluate whether to use YAFFS for a project on one of
our chips and having looked at the spec am unsure as to whether YAFFS
could/does support 16Bit NAND flash.
The only difference between 8Bit NAND flash adn 16bit as far as YAFFS is
concerned would be where the Bad Block information is stored and the fact
that a 2byte word is used instead of 1 byte.

Has any one used YAFFS with a 16bit device?

Are there any plans to support 16bit devices?

Many thanks

Adam
