This patchset adds support for IOMMU API for Tegra20(GART) and
Tegra30(SMMU). "struct iommu_ops" are implemented for both H/W IOMMU
modules.
Tested with "Ion memory manager" and "DMA mapping API"(*1).
This was originally developed with Tegra specific IOMMU
API(tegra_iovmm_*()) in:
git://nv-tegra.nvidia.com/linux-2.6.git.

v1:

*1: Reworking the DMA mapping code (especially on ARM)
