AEMIF stands for Asynchronous External Memory Interface and 34 is intended to provide a glue-less interface to a variety of 35 asynchronuous memory devices like ASRAM, NOR and NAND memory. A total 36 of 256M bytes of any of these memories can be accessed at a given 37 time via four chip selects with 64M byte access per chip select. 38 39config TI_EMIF 40 tristate "Texas Instruments EMIF driver" 41 depends on ARCH_OMAP2PLUS 42 select DDR 43 help 44 This driver is for the EMIF module available in Texas Instruments 45 SoCs. EMIF is an SDRAM controller that, based on its revision, 46 supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols. 47 This driver takes care of only LPDDR2 memories presently. The 48 functions of the driver includes re-configuring AC timing 49 parameters and other settings during frequency, voltage and 50 temperature changes 51 52config OMAP_GPMC 53 bool 54 select GPIOLIB 55 help 56 This driver is for the General Purpose Memory Controller (GPMC) 57 present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows 58 interfacing to a variety of asynchronous as well as synchronous 59 memory drives like NOR, NAND, OneNAND, SRAM. 60 61config OMAP_GPMC_DEBUG 62 bool "Enable GPMC debug output and skip reset of GPMC during init" 63 depends on OMAP_GPMC 64 help 65 Enables verbose debugging mostly to decode the bootloader provided 66 timings. To preserve the bootloader provided timings, the reset 67 of GPMC is skipped during init. Enable this during development to 68 configure devices connected to the GPMC bus. 69 70 NOTE: In addition to matching the register setup with the bootloader 71 you also need to match the GPMC FCLK frequency used by the 72 bootloader or else the GPMC timings won't be identical with the 73 bootloader timings. 74 75config MVEBU_DEVBUS 76 bool "Marvell EBU Device Bus Controller" 77 default y 78 depends on PLAT_ORION && OF 79 help 80 This driver is for the Device Bus controller available in some 81 Marvell EBU SoCs such as Discovery (mv78xx0), Orion (88f5xxx) and 82 Armada 370 and Armada XP. This controller allows to handle flash 83 devices such as NOR, NAND, SRAM, and FPGA. 84 85config TEGRA20_MC 86 bool "Tegra20 Memory Controller(MC) driver" 87 default y 88 depends on ARCH_TEGRA_2x_SOC 89 help 90 This driver is for the Memory Controller(MC) module available 91 in Tegra20 SoCs, mainly for a address translation fault 92 analysis, especially for IOMMU/GART(Graphics Address 93 Relocation Table) module. 94 95config FSL_CORENET_CF 96 tristate "Freescale CoreNet Error Reporting" 97 depends on FSL_SOC_BOOKE 98 help 99 Say Y for reporting of errors from the Freescale CoreNet 100 Coherency Fabric. Errors reported include accesses to 101 physical addresses that mapped by no local access window 102 (LAW) or an invalid LAW, as well as bad cache state that 103 represents a coherency violation. 104 105config FSL_IFC 106 bool 107 depends on FSL_SOC 108 109config JZ4780_NEMC 110 bool "Ingenic JZ4780 SoC NEMC driver" 111 default y 112 depends on MACH_JZ4780 113 help 114 This driver is for the NAND/External Memory Controller (NEMC) in 115 the Ingenic JZ4780. This controller is used to handle external 116 memory devices such as NAND and SRAM. 117 118config MTK_SMI 119 bool 120 depends on ARCH_MEDIATEK || COMPILE_TEST 121 help 122 This driver is for the Memory Controller module in MediaTek SoCs, 123 mainly help enable/disable iommu and control the power domain and 124 clocks for each local arbiter. 125 126source "drivers/memory/samsung/Kconfig" 127source "drivers/memory/tegra/Kconfig" 128 129endif 130
