         Support for the Allwinner IOMMU(System MMU) component. This
         enables H/W multimedia accellerators to see non-linear physical
         memory chunks as a linear memory in their address spaces.

         If unsure, say N here.

         Makes available some additional IOMMU profiling and debugging
         enables H/W multimedia accellerators to see non-linear physical
         memory chunks as a linear memory in their address spaces.

         Say Y here if you want to debug and trace iommu driver.

         Enables a suite of IOMMU unit tests.  The tests are runnable
         through debugfs. The impact of enabling this option to overal
         system performance should be minimal.
