6 bool "Memory Controller drivers"
11 tristate "ARM PL172 MPMC driver"
12 depends on ARM_AMBA && OF
14 This selects the ARM PrimeCell PL172 MultiPort Memory Controller.
15 If you have an embedded system with an AMBA bus and a PL172
16 controller, say Y or M here.
19 bool "Atmel (Multi-port DDR-)SDRAM Controller"
21 depends on ARCH_AT91 && OF
23 This driver is for Atmel SDRAM Controller or Atmel Multi-port
24 DDR-SDRAM Controller available on Atmel AT91SAM9 and SAMA5 SoCs.
25 Starting with the at91sam9g45, this controller supports SDR, DDR and
29 bool "Atmel EBI driver"
31 depends on ARCH_AT91 && OF
35 Driver for Atmel EBI controller.
36 Used to configure the EBI (external bus interface) when the device-
37 tree is used. This bus supports NANDs, external ethernet controller,
38 SRAMs, ATA devices, etc.
41 tristate "Texas Instruments AEMIF driver"
42 depends on (ARCH_DAVINCI || ARCH_KEYSTONE) && OF
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.
52 tristate "Texas Instruments EMIF driver"
53 depends on ARCH_OMAP2PLUS
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
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.
73 config OMAP_GPMC_DEBUG
74 bool "Enable GPMC debug output and skip reset of GPMC during init"
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.
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
88 tristate "Texas Instruments EMIF SRAM driver"
89 depends on (SOC_AM33XX || SOC_AM43XX) && SRAM
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.
98 bool "Marvell EBU Device Bus Controller"
100 depends on PLAT_ORION && OF
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.
107 config FSL_CORENET_CF
108 tristate "Freescale CoreNet Error Reporting"
109 depends on FSL_SOC_BOOKE
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.
119 depends on FSL_SOC || ARCH_LAYERSCAPE || SOC_LS1021A || COMPILE_TEST
123 bool "Ingenic JZ4780 SoC NEMC driver"
125 depends on MACH_JZ4780 || COMPILE_TEST
126 depends on HAS_IOMEM && OF
128 This driver is for the NAND/External Memory Controller (NEMC) in
129 the Ingenic JZ4780. This controller is used to handle external
130 memory devices such as NAND and SRAM.
134 depends on ARCH_MEDIATEK || COMPILE_TEST
136 This driver is for the Memory Controller module in MediaTek SoCs,
137 mainly help enable/disable iommu and control the power domain and
138 clocks for each local arbiter.
141 bool "Texas Instruments da8xx DDR2/mDDR driver"
142 depends on ARCH_DAVINCI_DA8XX
144 This driver is for the DDR2/mDDR Memory Controller present on
145 Texas Instruments da8xx SoCs. It's used to tweak various memory
146 controller configuration options.
