Subject: [PATCH 1/1] memory: tegra_ahb_enable_smmu() depends on TEGRA_IOMMU_SMMU
Date: Wed, 6 Feb 2013 20:34:26 +0200 [thread overview]
Message-ID: <1360175666-8377-1-git-send-email-hdoyu@nvidia.com> (raw)
New SoC, Tegra114 also uses SMMU. Change tegra_ahb_enable_smmu()'s
dependency from ARCH_TEGRA_3x_SOC to TEGRA_IOMMU_SMMU. No need to edit
whenever a new Tegra SoC comes.
The following combination caused build error, which this patch fixes.
CONFIG_ARCH_TEGRA_2x_SOC=y
\# CONFIG_ARCH_TEGRA_3x_SOC is not set
CONFIG_ARCH_TEGRA_114_SOC=y
drivers/iommu/tegra-smmu.c:485: undefined reference to 'tegra_ahb_enable_smmu'
