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 |
