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 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
93 config MMC_SDHCI_OF_ESDHC
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
113 config MMC_SDHCI_PLTFM
114 tristate "SDHCI support on the platform specific bus"
117 This selects the platform specific bus support for Secure Digital Host
118 Controller Interface.
120 If you have a controller with this interface, say Y or M here.
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_SPEAR
140 tristate "SDHCI support on ST SPEAr platform"
141 depends on MMC_SDHCI && PLAT_SPEAR
143 This selects the Secure Digital Host Controller Interface (SDHCI)
144 often referrered to as the HSMMC block in some of the ST SPEAR range
147 If you have a controller with this interface, say Y or M here.
151 config MMC_SDHCI_S3C_DMA
152 bool "DMA support on S3C SDHCI"
153 depends on MMC_SDHCI_S3C && EXPERIMENTAL
155 Enable DMA support on the Samsung S3C SDHCI glue. The DMA
156 has proved to be problematic if the controller encounters
157 certain errors, and thus should be treated with care.
162 tristate "TI OMAP Multimedia Card Interface support"
164 select TPS65010 if MACH_OMAP_H2
166 This selects the TI OMAP Multimedia card Interface.
167 If you have an OMAP board with a Multimedia Card slot,

178 Multimedia Card slot, say Y or M here.
183 tristate "Winbond W83L51xD SD/MMC Card Interface support"
184 depends on ISA_DMA_API
186 This selects the Winbond(R) W83L51xD Secure digital and

223 Card slot, say Y or M here.
229 config MMC_ATMELMCI_DMA
230 bool "Atmel MCI DMA support (EXPERIMENTAL)"
231 depends on MMC_ATMELMCI && AVR32 && DMA_ENGINE && EXPERIMENTAL
233 Say Y here to have the Atmel MCI driver use a DMA engine to
234 do data transfers and thus increase the throughput and
235 reduce the CPU utilization. Note that this is highly
236 experimental and may cause the driver to lock up.
241 tristate "Motorola i.MX Multimedia Card Interface support"
244 This selects the Motorola i.MX Multimedia card Interface.
245 If you have a i.MX platform with a Multimedia Card slot,
251 tristate "Qualcomm MSM 7X00A SDCC Controller Support"

269 depends on EXPERIMENTAL && PCI
272 Say Y here if you want to be able to access MMC/SD cards with
273 the Texas Instruments(R) Flash Media card reader, found in many
275 This option 'selects' (turns on, enables) 'TIFM_CORE', but you
276 probably also need appropriate card reader host adapter, such as
277 'Misc devices: TI Flash Media PCI74xx/PCI76xx host adapter support
280 To compile this driver as a module, choose M here: the
281 module will be called tifm_sd.

296 depends on ARCH_DAVINCI
298 This selects the TI DAVINCI Multimedia card Interface.
299 If you have an DAVINCI board with a Multimedia Card slot,
300 say Y or M here. If unsure, say N.
303 tristate "MMC/SD/SDIO over SPI"
304 depends on SPI_MASTER && !HIGHMEM && HAS_DMA
308 Some systems access MMC/SD/SDIO cards using a SPI controller
309 instead of using a "native" MMC/SD/SDIO controller. This has a
310 disadvantage of being relatively high overhead, but a compensating
311 advantage of working on many systems without dedicated MMC/SD/SDIO
314 If unsure, or if your system has no SPI master driver, say N.

331 Enable the hardware support for SDIO interrupts instead of using
332 the generic polling code.
335 prompt "Samsung S3C SD/MMC transfer code"
339 bool "Use PIO transfers only"
341 Use PIO to transfer data between memory and the hardware.
343 PIO is slower than DMA as it requires CPU instructions to
344 move the data. This has been the traditional default for
348 bool "Use DMA transfers only (EXPERIMENTAL)"
349 depends on EXPERIMENTAL
351 Use DMA to transfer data between memory and the hardare.
353 Currently, the DMA support in this driver seems to not be
354 working properly and needs to be debugged before this
357 config MMC_S3C_PIODMA
358 bool "Support for both PIO and DMA (EXPERIMENTAL)"
360 Compile both the PIO and DMA transfer routines into the
361 driver and let the platform select at run-time which one
364 See notes for the DMA option.
368 config MMC_SDRICOH_CS
369 tristate "MMC/SD driver for Ricoh Bay1Controllers (EXPERIMENTAL)"
370 depends on EXPERIMENTAL && PCI && PCMCIA
372 Say Y here if your Notebook reports a Ricoh Bay1Controller PCMCIA
373 card whenever you insert a MMC or SD card into the card slot.
375 To compile this driver as a module, choose M here: the
376 module will be called sdricoh_cs.
379 tristate "Toshiba Mobile IO Controller (TMIO) MMC/SD function support"
380 depends on MFD_TMIO || MFD_ASIC3 || MFD_SH_MOBILE_SDHI
382 This provides support for the SD/MMC cell found in TC6393XB,
383 T7L66XB and also HTC ASIC3

395 will be called cb710-mmc.
398 tristate "VIA SD/MMC Card Reader Driver"
