Hi Sachin,

Hmm, do you _really_ use this feature on ORIGEN board now?

As I know, the EXYNOS System MMU driver will be changed like a form of omap
and msm soon maybe it's within 1 or 2 weeks. So if this is not required on
ORIGEN now, I'd like to wait for new EXYNOS System MMU driver.

Thanks.

Best regards,
Kgene.
