Thank you a lot.

The next IOMMU driver defines just one platform device for a H/W device.
Thus, it defines just one SYSMMU_MFC platform device, for example.
(the previous one defines 2 platform devices for SYSMMU_MFC)

Exynos4210 has 2 iommu controllers for MFC device - one for each memory bus.
Each MFC bus can address 128MiB of IO address space. Do you mean that the new driver
will merge these 2 controllers into one? This way we will lose half of address space
for MFC device.

The situation seems somewhat different from our use of MFC. I also
heard from Jungtae Park
that it is better to define separate platform devices for the system
MMUs of MFC.
