ARM: IOMMU: Tegra20: Add iommu_ops for GART driver
Tegra 20 IOMMU H/W, GART (Graphics Address Relocation Table). This patch implements struct iommu_ops for GART for the upper IOMMU API. This H/W module supports only single virtual address space(domain), and manages a single level 1-to-1 mapping H/W translation page table. [With small fixes by Joerg Roedel] Signed-off-by: Hiroshi DOYU <hdoyu@nvidia.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
