PATCH v2 1/1 iommu/tegra: smmu: Change SMMU's dependency on ARCH_TEGRA

Theoretically TEGRA_IOMMU_SMMU depends on ARCH_TEGRA_3x_SOC and ARCH_TEGRA_114_SOC only. This patch allows a Tegra20 only kernel to enable SMMU(Tegra20 doesn't have a SMMU), which could avoid editing this Kconfig entry every time we add a new chip later.

Is there any chance to get this patch merged in v3.9?

Also there's another patch for v3.9:

Also there's another patch for v3.9:

http://lists.linuxfoundation.org/pipermail/iommu/2013-January/005129.html

The above link is pointing this mail wrongly. So the pending patches for v3.9 are:

- [v3 1/1] iommu/tegra: smmu: Support variable MMIO ranges/blocks
http://lists.linuxfoundation.org/pipermail/iommu/2013-January/005127.html

- [v2 1/1] iommu/tegra: smmu: Change SMMU's dependency on ARCH_TEGRA
http://lists.linuxfoundation.org/pipermail/iommu/2013-January/005129.html

Joerg, could you take them merged in for v3.9?
