# # Memory devices # menuconfig MEMORY bool "Memory Controller drivers" if MEMORY config TI_EMIF tristate "Texas Instruments EMIF driver" depends on ARCH_OMAP2PLUS select DDR help This driver is for the EMIF module available in Texas Instruments SoCs. EMIF is an SDRAM controller that, based on its revision, supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols. This driver takes care of only LPDDR2 memories presently. The functions of the driver includes re-configuring AC timing parameters and other settings during frequency, voltage and temperature changes config TEGRA20_MC bool "Tegra20 Memory Controller(MC) driver" default y depends on ARCH_TEGRA_2x_SOC help This driver is for the Memory Controller(MC) module available in Tegra20 SoCs, mainly for a address translation fault analysis, especially for IOMMU/GART(Graphics Address Relocation Table) module. config TEGRA30_MC bool "Tegra30 Memory Controller(MC) driver" default y depends on ARCH_TEGRA_3x_SOC help This driver is for the Memory Controller(MC) module available in Tegra30 SoCs, mainly for a address translation fault analysis, especially for IOMMU/SMMU(System Memory Management Unit) module. endif
