## 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
