[Yaffs] yaffs2 direct interface(tags)

Hello

Form the code of yaffs2, direct interface, it looks like there is no
function like yaffs_LoadTagsIntoSpare().
Instead in "yaffs_flashif.c", an attempt is made to write to the flash
with tags.

How does this spare concept get replaced by Extended tags?

Is it necessary to use pack and unpack tags for yaffs2 , or can we
directly pass a pointer to
extended tags to the driver?
Which pack, unpack routine should be used for yaffs2?


I am using 128 MB NAND flash ( 2K + 64) bytes page

Thanks
Abhishek
