## Memory devices# menuconfig MEMORY	bool "Memory Controller drivers" if MEMORY config ARM_PL172_MPMC	tristate "ARM PL172 MPMC driver"	depends on ARM_AMBA && OF	help	  This selects the ARM PrimeCell PL172 MultiPort Memory Controller.	  If you have an embedded system with an AMBA bus and a PL172	  controller, say Y or M here. config ATMEL_SDRAMC	bool "Atmel (Multi-port DDR-)SDRAM Controller"	default y	depends on ARCH_AT91 && OF	help	  This driver is for Atmel SDRAM Controller or Atmel Multi-port	  DDR-SDRAM Controller available on Atmel AT91SAM9 and SAMA5 SoCs.	  Starting with the at91sam9g45, this controller supports SDR, DDR and	  LP-DDR memories. config ATMEL_EBI	bool "Atmel EBI driver"	default y	depends on ARCH_AT91 && OF	select MFD_SYSCON	select MFD_ATMEL_SMC	help	  Driver for Atmel EBI controller.	  Used to configure the EBI (external bus interface) when the device-	  tree is used. This bus supports NANDs, external ethernet controller,	  SRAMs, ATA devices, etc. config TI_AEMIF	tristate "Texas Instruments AEMIF driver"	depends on (ARCH_DAVINCI || ARCH_KEYSTONE) && OF	help	  This driver is for the AEMIF module available in Texas Instruments	  SoCs. AEMIF stands for Asynchronous External Memory Interface and	  is intended to provide a glue-less interface to a variety of	  asynchronuous memory devices like ASRAM, NOR and NAND memory. A total	  of 256M bytes of any of these memories can be accessed at a given	  time via four chip selects with 64M byte access per chip select. 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 OMAP_GPMC	bool	select GPIOLIB	help	  This driver is for the General Purpose Memory Controller (GPMC)	  present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows	  interfacing to a variety of asynchronous as well as synchronous	  memory drives like NOR, NAND, OneNAND, SRAM. config OMAP_GPMC_DEBUG	bool "Enable GPMC debug output and skip reset of GPMC during init"	depends on OMAP_GPMC	help	  Enables verbose debugging mostly to decode the bootloader provided	  timings. To preserve the bootloader provided timings, the reset	  of GPMC is skipped during init. Enable this during development to	  configure devices connected to the GPMC bus. 	  NOTE: In addition to matching the register setup with the bootloader	  you also need to match the GPMC FCLK frequency used by the	  bootloader or else the GPMC timings won't be identical with the	  bootloader timings. config MVEBU_DEVBUS	bool "Marvell EBU Device Bus Controller"	default y	depends on PLAT_ORION && OF	help	  This driver is for the Device Bus controller available in some	  Marvell EBU SoCs such as Discovery (mv78xx0), Orion (88f5xxx) and	  Armada 370 and Armada XP. This controller allows to handle flash	  devices such as NOR, NAND, SRAM, and FPGA. 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 FSL_CORENET_CF	tristate "Freescale CoreNet Error Reporting"	depends on FSL_SOC_BOOKE	help	  Say Y for reporting of errors from the Freescale CoreNet	  Coherency Fabric.  Errors reported include accesses to	  physical addresses that mapped by no local access window	  (LAW) or an invalid LAW, as well as bad cache state that	  represents a coherency violation. config FSL_IFC	bool	depends on FSL_SOC || ARCH_LAYERSCAPE || SOC_LS1021A config JZ4780_NEMC	bool "Ingenic JZ4780 SoC NEMC driver"	default y	depends on MACH_JZ4780	help	  This driver is for the NAND/External Memory Controller (NEMC) in	  the Ingenic JZ4780. This controller is used to handle external	  memory devices such as NAND and SRAM. config MTK_SMI	bool	depends on ARCH_MEDIATEK || COMPILE_TEST	help	  This driver is for the Memory Controller module in MediaTek SoCs,	  mainly help enable/disable iommu and control the power domain and	  clocks for each local arbiter. config DA8XX_DDRCTL	bool "Texas Instruments da8xx DDR2/mDDR driver"	depends on ARCH_DAVINCI_DA8XX	help	  This driver is for the DDR2/mDDR Memory Controller present on	  Texas Instruments da8xx SoCs. It's used to tweak various memory	  controller configuration options. source "drivers/memory/samsung/Kconfig"source "drivers/memory/tegra/Kconfig" endif
