[Yaffs] mkyaffs with yaffs2

Good day, All.

I've checked, that there was update of yaffs utils - mkyaffs2image. It's a
perfect tool and looks like it works fine. But I can't see any updates for
mkyaffs. I've made a short look on mkyaffs sources, and looks like it's
unable to work with yaffs2 image. Does someone try to patch it for support
yaffs2 image?

Thank you,
