This bus supports NANDs, external ethernet controller, 38 SRAMs, ATA devices, etc. 39 40config TI_AEMIF 41 tristate "Texas Instruments AEMIF driver" 42 depends on (ARCH_DAVINCI || ARCH_KEYSTONE) && OF 43 help 44 This driver is for the AEMIF module available in Texas Instruments 45 SoCs. AEMIF stands for Asynchronous External Memory Interface and 46 is intended to provide a glue-less interface to a variety of 47 asynchronuous memory devices like ASRAM, NOR and NAND memory. A total 48 of 256M bytes of any of these memories can be accessed at a given 49 time via four chip selects with 64M byte access per chip select. 50 51config TI_EMIF 52 tristate "Texas Instruments EMIF driver" 53 depends on ARCH_OMAP2PLUS 54 select DDR 55 help 56 This driver is for the EMIF module available in Texas Instruments 57 SoCs. EMIF is an SDRAM controller that, based on its revision, 58 supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols. 59 This driver takes care of only LPDDR2 memories presently. The 60 functions of the driver includes re-configuring AC timing 61 parameters and other settings during frequency, voltage and 62 temperature changes 63 64config OMAP_GPMC 65 bool 66 select GPIOLIB 67 help 68 This driver is for the General Purpose Memory Controller (GPMC) 69 present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows 70 interfacing to a variety of asynchronous as well as synchronous 71 memory drives like NOR, NAND, OneNAND, SRAM. 72 73config OMAP_GPMC_DEBUG 74 bool "Enable GPMC debug output and skip reset of GPMC during init" 75 depends on OMAP_GPMC 76 help 77 Enables verbose debugging mostly to decode the bootloader provided 78 timings. To preserve the bootloader provided timings, the reset 79 of GPMC is skipped during init. Enable this during development to 80 configure devices connected to the GPMC bus. 81 82 NOTE: In addition to matching the register setup with the bootloader 83 you also need to match the GPMC FCLK frequency used by the 84 bootloader or else the GPMC timings won't be identical with the 85 bootloader timings. 86 87config TI_EMIF_SRAM 88 tristate "Texas Instruments EMIF SRAM driver" 89 depends on (SOC_AM33XX || SOC_AM43XX) && SRAM 90 help 91 This driver is for the EMIF module available on Texas Instruments 92 AM33XX and AM43XX SoCs and is required for PM. Certain parts of 93 the EMIF PM code must run from on-chip SRAM late in the suspend 94 sequence so this driver provides several relocatable PM functions 95 for the SoC PM code to use. 96 97config MVEBU_DEVBUS 98 bool "Marvell EBU Device Bus Controller" 99 default y 100 depends on PLAT_ORION && OF 101 help 102 This driver is for the Device Bus controller available in some 103 Marvell EBU SoCs such as Discovery (mv78xx0), Orion (88f5xxx) and 104 Armada 370 and Armada XP. This controller allows to handle flash 105 devices such as NOR, NAND, SRAM, and FPGA. 106 107config FSL_CORENET_CF 108 tristate "Freescale CoreNet Error Reporting" 109 depends on FSL_SOC_BOOKE 110 help 111 Say Y for reporting of errors from the Freescale CoreNet 112 Coherency Fabric. Errors reported include accesses to 113 physical addresses that mapped by no local access window 114 (LAW) or an invalid LAW, as well as bad cache state that 115 represents a coherency violation. 116 117config FSL_IFC 118 bool 119 depends on FSL_SOC || ARCH_LAYERSCAPE || SOC_LS1021A || COMPILE_TEST 120 depends on HAS_IOMEM 121 122config JZ4780_NEMC 123 bool "Ingenic JZ4780 SoC NEMC driver" 124 default y 125 depends on MACH_JZ4780 || COMPILE_TEST 126 depends on HAS_IOMEM && OF 127 help 128 This driver is for the NAND/External Memory Controller (NEMC) in 129 the Ingenic JZ4780.
