5 comment "MMC/SD/SDIO Host Controller Drivers"
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.
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 tristate "Ricoh MMC Controller Disabler (EXPERIMENTAL)"
73 depends on MMC_SDHCI_PCI
75 This selects the disabler for the 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 driver even if you don't
80 have a Ricoh based card reader.
83 To compile this driver as a module, choose M here:
84 the module will be called ricoh_mmc.
89 tristate "SDHCI support on OpenFirmware platforms"
90 depends on MMC_SDHCI && PPC_OF
92 This selects the OF support for Secure Digital Host Controller
97 config MMC_SDHCI_OF_ESDHC
98 bool "SDHCI OF support for the Freescale eSDHC controller"
99 depends on MMC_SDHCI_OF
100 select MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER
102 This selects the Freescale eSDHC controller support.
106 config MMC_SDHCI_PLTFM
107 tristate "SDHCI support on the platform specific bus"
110 This selects the platform specific bus support for Secure Digital Host
111 Controller Interface.

121 This selects the Secure Digital Host Controller Interface (SDHCI)
122 often referrered to as the HSMMC block in some of the Samsung S3C
125 Note, due to the problems with DMA, the DMA support is only
126 available with CONFIG_EXPERIMENTAL is selected.
128 If you have a controller with this interface, say Y or M here.
132 config MMC_SDHCI_S3C_DMA
133 bool "DMA support on S3C SDHCI"
134 depends on MMC_SDHCI_S3C && EXPERIMENTAL
136 Enable DMA support on the Samsung S3C SDHCI glue. The DMA
137 has proved to be problematic if the controller encounters
138 certain errors, and thus should be treated with care.
143 tristate "TI OMAP Multimedia Card Interface support"
145 select TPS65010 if MACH_OMAP_H2
147 This selects the TI OMAP Multimedia card Interface.
148 If you have an OMAP board with a Multimedia Card slot,

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

252 Say Y here if you want to be able to access MMC/SD cards with
253 the Texas Instruments(R) Flash Media card reader, found in many
255 This option 'selects' (turns on, enables) 'TIFM_CORE', but you
256 probably also need appropriate card reader host adapter, such as
257 'Misc devices: TI Flash Media PCI74xx/PCI76xx host adapter support

279 If you have an DAVINCI board with a Multimedia Card slot,
280 say Y or M here. If unsure, say N.
283 tristate "MMC/SD/SDIO over SPI"
284 depends on SPI_MASTER && !HIGHMEM && HAS_DMA
288 Some systems access MMC/SD/SDIO cards using a SPI controller
289 instead of using a "native" MMC/SD/SDIO controller. This has a
290 disadvantage of being relatively high overhead, but a compensating
291 advantage of working on many systems without dedicated MMC/SD/SDIO
294 If unsure, or if your system has no SPI master driver, say N.
297 tristate "Samsung S3C SD/MMC Card Interface support"
298 depends on ARCH_S3C2410

301 Samsung's S3C2410, S3C2412, S3C2440, S3C2442 CPUs.
302 If you have a board based on one of those and a MMC/SD
303 slot, say Y or M here.
307 config MMC_S3C_HW_SDIO_IRQ
308 bool "Hardware support for SDIO IRQ"
311 Enable the hardware support for SDIO interrupts instead of using
312 the generic polling code.
315 prompt "Samsung S3C SD/MMC transfer code"
319 bool "Use PIO transfers only"
321 Use PIO to transfer data between memory and the hardware.

324 move the data. This has been the traditional default for
328 bool "Use DMA transfers only (EXPERIMENTAL)"
329 depends on EXPERIMENTAL
331 Use DMA to transfer data between memory and the hardare.
333 Currently, the DMA support in this driver seems to not be
334 working properly and needs to be debugged before this
