8 tristate "ARM AMBA Multimedia Card Interface support"
11 This selects the ARM(R) AMBA(R) PrimeCell Multimedia Card
12 Interface (PL180 and PL181) support. If you have an ARM(R)
13 platform with a Multimedia Card slot, say Y or M here.
18 tristate "Intel PXA25x/26x/27x Multimedia Card Interface support"
21 This selects the Intel(R) PXA(R) Multimedia card Interface.
22 If you have a PXA(R) platform with a Multimedia Card slot,
28 tristate "Secure Digital Host Controller Interface support"
31 This selects the generic Secure Digital Host Controller Interface.
32 It is used by manufacturers such as Texas Instruments(R), Ricoh(R)
33 and Toshiba(R). Most controllers found in laptops are of this type.
35 If you have a controller with this interface, say Y or M here. You
36 also need to enable an appropriate bus interface.
40 config MMC_SDHCI_IO_ACCESSORS
44 This is silent Kconfig symbol that is selected by the drivers that
45 need to overwrite SDHCI IO memory accessors.
47 config MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER
49 select MMC_SDHCI_IO_ACCESSORS
51 This option is selected by drivers running on big endian hosts
52 and performing I/O to a SDHCI controller through a bus that
53 implements a hardware byte swapper using a 32-bit datum.
54 This endian mapping mode is called "data invariance" and
55 has the effect of scrambling the addresses and formats of data
56 accessed in sizes other than the datum size.
58 This is the case for the Freescale eSDHC and Nintendo Wii SDHCI.
61 tristate "SDHCI support on PCI bus"
62 depends on MMC_SDHCI && PCI
64 This selects the PCI Secure Digital Host Controller Interface.
65 Most controllers found today are PCI devices.
67 If you have a controller with this interface, say Y or M here.
72 bool "Ricoh MMC Controller Disabler (EXPERIMENTAL)"
73 depends on MMC_SDHCI_PCI
75 This adds a pci quirk to disable Ricoh MMC Controller. This
76 proprietary controller is unnecessary because the SDHCI driver
77 supports MMC cards on the SD controller, but if it is not
78 disabled, it will steal the MMC cards away - rendering them
79 useless. It is safe to select this even if you don't
80 have a Ricoh based card reader.
85 tristate "SDHCI support on OpenFirmware platforms"
86 depends on MMC_SDHCI && PPC_OF
88 This selects the OF support for Secure Digital Host Controller

94 bool "SDHCI OF support for the Freescale eSDHC controller"
95 depends on MMC_SDHCI_OF
96 select MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER
98 This selects the Freescale eSDHC controller support.
102 config MMC_SDHCI_OF_HLWD
103 bool "SDHCI OF support for the Nintendo Wii SDHCI controllers"
104 depends on MMC_SDHCI_OF
105 select MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER
107 This selects the Secure Digital Host Controller Interface (SDHCI)
108 found in the "Hollywood" chipset of the Nintendo Wii video game

125 tristate "SDHCI support on Samsung S3C SoC"
126 depends on MMC_SDHCI && (PLAT_S3C24XX || PLAT_S3C64XX)
128 This selects the Secure Digital Host Controller Interface (SDHCI)
129 often referrered to as the HSMMC block in some of the Samsung S3C
132 Note, due to the problems with DMA, the DMA support is only
133 available with CONFIG_EXPERIMENTAL is selected.
135 If you have a controller with this interface, say Y or M here.
139 config MMC_SDHCI_S3C_DMA
140 bool "DMA support on S3C SDHCI"
141 depends on MMC_SDHCI_S3C && EXPERIMENTAL
143 Enable DMA support on the Samsung S3C SDHCI glue. The DMA
144 has proved to be problematic if the controller encounters
145 certain errors, and thus should be treated with care.

216 config MMC_ATMELMCI_DMA
217 bool "Atmel MCI DMA support (EXPERIMENTAL)"
218 depends on MMC_ATMELMCI && AVR32 && DMA_ENGINE && EXPERIMENTAL
220 Say Y here to have the Atmel MCI driver use a DMA engine to
221 do data transfers and thus increase the throughput and
222 reduce the CPU utilization. Note that this is highly
223 experimental and may cause the driver to lock up.
228 tristate "Motorola i.MX Multimedia Card Interface support"
231 This selects the Motorola i.MX Multimedia card Interface.
232 If you have a i.MX platform with a Multimedia Card slot,
238 tristate "Qualcomm MSM 7X00A SDCC Controller Support"

290 tristate "MMC/SD/SDIO over SPI"
291 depends on SPI_MASTER && !HIGHMEM && HAS_DMA
295 Some systems access MMC/SD/SDIO cards using a SPI controller
296 instead of using a "native" MMC/SD/SDIO controller. This has a
297 disadvantage of being relatively high overhead, but a compensating
298 advantage of working on many systems without dedicated MMC/SD/SDIO
301 If unsure, or if your system has no SPI master driver, say N.
