7 bool "Memory Controller drivers"
12 tristate "ARM PL172 MPMC driver"
13 depends on ARM_AMBA && OF
15 This selects the ARM PrimeCell PL172 MultiPort Memory Controller.
16 If you have an embedded system with an AMBA bus and a PL172
17 controller, say Y or M here.
20 bool "Atmel (Multi-port DDR-)SDRAM Controller"
22 depends on ARCH_AT91 && OF
24 This driver is for Atmel SDRAM Controller or Atmel Multi-port
25 DDR-SDRAM Controller available on Atmel AT91SAM9 and SAMA5 SoCs.
26 Starting with the at91sam9g45, this controller supports SDR, DDR and
30 bool "Atmel EBI driver"
32 depends on ARCH_AT91 && OF
36 Driver for Atmel EBI controller.
37 Used to configure the EBI (external bus interface) when the device-
38 tree is used. This bus supports NANDs, external ethernet controller,
39 SRAMs, ATA devices, etc.
42 tristate "Texas Instruments AEMIF driver"
43 depends on (ARCH_DAVINCI || ARCH_KEYSTONE) && OF
45 This driver is for the AEMIF module available in Texas Instruments
46 SoCs. AEMIF stands for Asynchronous External Memory Interface and
47 is intended to provide a glue-less interface to a variety of
48 asynchronuous memory devices like ASRAM, NOR and NAND memory. A total
49 of 256M bytes of any of these memories can be accessed at a given
50 time via four chip selects with 64M byte access per chip select.
53 tristate "Texas Instruments EMIF driver"
54 depends on ARCH_OMAP2PLUS
57 This driver is for the EMIF module available in Texas Instruments
58 SoCs. EMIF is an SDRAM controller that, based on its revision,
59 supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
60 This driver takes care of only LPDDR2 memories presently. The
61 functions of the driver includes re-configuring AC timing
62 parameters and other settings during frequency, voltage and
69 This driver is for the General Purpose Memory Controller (GPMC)
70 present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows
71 interfacing to a variety of asynchronous as well as synchronous
72 memory drives like NOR, NAND, OneNAND, SRAM.
74 config OMAP_GPMC_DEBUG
75 bool "Enable GPMC debug output and skip reset of GPMC during init"
78 Enables verbose debugging mostly to decode the bootloader provided
79 timings. To preserve the bootloader provided timings, the reset
80 of GPMC is skipped during init. Enable this during development to
81 configure devices connected to the GPMC bus.
83 NOTE: In addition to matching the register setup with the bootloader
84 you also need to match the GPMC FCLK frequency used by the
85 bootloader or else the GPMC timings won't be identical with the
89 tristate "Texas Instruments EMIF SRAM driver"
90 depends on (SOC_AM33XX || SOC_AM43XX) && SRAM
92 This driver is for the EMIF module available on Texas Instruments
93 AM33XX and AM43XX SoCs and is required for PM. Certain parts of
94 the EMIF PM code must run from on-chip SRAM late in the suspend
95 sequence so this driver provides several relocatable PM functions
96 for the SoC PM code to use.
99 bool "Marvell EBU Device Bus Controller"
101 depends on PLAT_ORION && OF
103 This driver is for the Device Bus controller available in some
104 Marvell EBU SoCs such as Discovery (mv78xx0), Orion (88f5xxx) and
105 Armada 370 and Armada XP. This controller allows to handle flash
106 devices such as NOR, NAND, SRAM, and FPGA.
108 config FSL_CORENET_CF
109 tristate "Freescale CoreNet Error Reporting"
110 depends on FSL_SOC_BOOKE
112 Say Y for reporting of errors from the Freescale CoreNet
113 Coherency Fabric. Errors reported include accesses to
114 physical addresses that mapped by no local access window
115 (LAW) or an invalid LAW, as well as bad cache state that
116 represents a coherency violation.
120 depends on FSL_SOC || ARCH_LAYERSCAPE || SOC_LS1021A || COMPILE_TEST
124 bool "Ingenic JZ4780 SoC NEMC driver"
126 depends on MACH_JZ4780 || COMPILE_TEST
127 depends on HAS_IOMEM && OF
129 This driver is for the NAND/External Memory Controller (NEMC) in
130 the Ingenic JZ4780. This controller is used to handle external
131 memory devices such as NAND and SRAM.
135 depends on ARCH_MEDIATEK || COMPILE_TEST
137 This driver is for the Memory Controller module in MediaTek SoCs,
138 mainly help enable/disable iommu and control the power domain and
139 clocks for each local arbiter.
142 bool "Texas Instruments da8xx DDR2/mDDR driver"
143 depends on ARCH_DAVINCI_DA8XX
145 This driver is for the DDR2/mDDR Memory Controller present on
146 Texas Instruments da8xx SoCs. It's used to tweak various memory
147 controller configuration options.
150 tristate "ARM PL35X Static Memory Controller(SMC) driver"
155 This driver is for the ARM PL351/PL353 Static Memory
156 Controller(SMC) module.
