13 help
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.

22 help
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
26 LP-DDR memories.

30 depends on (ARCH_DAVINCI || ARCH_KEYSTONE) && OF
31 help
32 This driver is for the AEMIF module available in Texas Instruments
33 SoCs. 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.

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

52config OMAP_GPMC
53 bool
54 help
55 This driver is for the General Purpose Memory Controller (GPMC)
56 present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows
57 interfacing to a variety of asynchronous as well as synchronous
58 memory drives like NOR, NAND, OneNAND, SRAM.

60config OMAP_GPMC_DEBUG
61 bool "Enable GPMC debug output and skip reset of GPMC during init"
62 depends on OMAP_GPMC
63 help
64 Enables verbose debugging mostly to decode the bootloader provided
65 timings. To preserve the bootloader provided timings, the reset
66 of GPMC is skipped during init. Enable this during development to
67 configure devices connected to the GPMC bus.
68
69 NOTE: In addition to matching the register setup with the bootloader
70 you also need to match the GPMC FCLK frequency used by the
71 bootloader or else the GPMC timings won't be identical with the
72 bootloader timings.

74config MVEBU_DEVBUS
75 bool "Marvell EBU Device Bus Controller"
76 default y
77 depends on PLAT_ORION && OF
78 help
79 This driver is for the Device Bus controller available in some
80 Marvell EBU SoCs such as Discovery (mv78xx0), Orion (88f5xxx) and
81 Armada 370 and Armada XP. This controller allows to handle flash
82 devices such as NOR, NAND, SRAM, and FPGA.

85 bool "Tegra20 Memory Controller(MC) driver"
86 default y
87 depends on ARCH_TEGRA_2x_SOC
88 help
89 This driver is for the Memory Controller(MC) module available
90 in Tegra20 SoCs, mainly for a address translation fault
91 analysis, especially for IOMMU/GART(Graphics Address
92 Relocation Table) module.

95 tristate "Freescale CoreNet Error Reporting"
96 depends on FSL_SOC_BOOKE
97 help
98 Say Y for reporting of errors from the Freescale CoreNet
99 Coherency Fabric. Errors reported include accesses to
100 physical addresses that mapped by no local access window
101 (LAW) or an invalid LAW, as well as bad cache state that
102 represents a coherency violation.

113 This driver is for the NAND/External Memory Controller (NEMC) in
114 the Ingenic JZ4780. This controller is used to handle external
115 memory devices such as NAND and SRAM.
