[Yaffs] SELinux on YFFS2

Hello,

Looking for a security module for TI OMAP 3530 processor + embedded Linux
based system. The filesystem of my board is YFFS2.
My team decided for SELinux (after doing 2 months RnD) but the problem is
xattr is not supported on YFFS2.

Can some please guide me regarding xattr on YFFS2 file system.
Any suggestion is most welcome.

Regards,
~Nishant
