There are 2 options:

1) If you have access to the oob/spare area on the NAND then you can try using
the yaffs2 code in yaffs1 backward compatibility mode.

# mount -t yaffs /dev/mtdblock0 /y

2) If you do not have access to the oob/spare area then try the inband tags
mode.

# mount -t yaffs2 -o"inband-tags" /dev/mtdblock0 /y
