The single patch 07/12 is merged to mainline from v6 patches.
v10 patch is more advanced than v6.
Of course, much more is changed.
You can refer the v9 patch what is changed since v6.

I just test if the System MMU is correctly enabled and disabled,
if page table is correctly maintained.
It is done with IOMMU API call from custom driver/device and applications.

The test does not involve working with master IPs such as MFC, FIMC and so on.
