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 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_OF_HLWD
107 bool "SDHCI OF support for the Nintendo Wii SDHCI controllers"
108 depends on MMC_SDHCI_OF
109 select MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER
111 This selects the Secure Digital Host Controller Interface (SDHCI)
112 found in the "Hollywood" chipset of the Nintendo Wii video game
117 config MMC_SDHCI_PLTFM
118 tristate "SDHCI support on the platform specific bus"
121 This selects the platform specific bus support for Secure Digital Host
122 Controller Interface.
124 If you have a controller with this interface, say Y or M here.
129 tristate "SDHCI support on Samsung S3C SoC"
130 depends on MMC_SDHCI && (PLAT_S3C24XX || PLAT_S3C64XX)
132 This selects the Secure Digital Host Controller Interface (SDHCI)
133 often referrered to as the HSMMC block in some of the Samsung S3C
136 Note, due to the problems with DMA, the DMA support is only
137 available with CONFIG_EXPERIMENTAL is selected.
139 If you have a controller with this interface, say Y or M here.
143 config MMC_SDHCI_S3C_DMA
144 bool "DMA support on S3C SDHCI"
145 depends on MMC_SDHCI_S3C && EXPERIMENTAL
147 Enable DMA support on the Samsung S3C SDHCI glue. The DMA
148 has proved to be problematic if the controller encounters
149 certain errors, and thus should be treated with care.
154 tristate "TI OMAP Multimedia Card Interface support"
156 select TPS65010 if MACH_OMAP_H2
158 This selects the TI OMAP Multimedia card Interface.
159 If you have an OMAP board with a Multimedia Card slot,

170 Multimedia Card slot, say Y or M here.
175 tristate "Winbond W83L51xD SD/MMC Card Interface support"
176 depends on ISA_DMA_API
178 This selects the Winbond(R) W83L51xD Secure digital and
179 Multimedia card Interface.
180 If you have a machine with a integrated W83L518D or W83L519D
181 SD/MMC card reader, say Y or M here.
186 tristate "Alchemy AU1XX0 MMC Card Interface support"
187 depends on SOC_AU1200
189 This selects the AMD Alchemy(R) Multimedia card interface.
190 If you have a Alchemy platform with a MMC slot, say Y or M here.

214 Card slot, say Y or M here.
220 config MMC_ATMELMCI_DMA
221 bool "Atmel MCI DMA support (EXPERIMENTAL)"
222 depends on MMC_ATMELMCI && AVR32 && DMA_ENGINE && EXPERIMENTAL
224 Say Y here to have the Atmel MCI driver use a DMA engine to
225 do data transfers and thus increase the throughput and
226 reduce the CPU utilization. Note that this is highly
227 experimental and may cause the driver to lock up.
232 tristate "Motorola i.MX Multimedia Card Interface support"
235 This selects the Motorola i.MX Multimedia card Interface.
236 If you have a i.MX platform with a Multimedia Card slot,
242 tristate "Qualcomm MSM 7X00A SDCC Controller Support"
243 depends on MMC && ARCH_MSM
245 This provides support for the SD/MMC cell found in the
246 MSM 7X00A controllers from Qualcomm.
249 tristate "Freescale i.MX2/3 Multimedia Card Interface support"
252 This selects the Freescale i.MX2/3 Multimedia card Interface.
253 If you have a i.MX platform with a Multimedia Card slot,
259 tristate "TI Flash Media MMC/SD Interface support (EXPERIMENTAL)"
260 depends on EXPERIMENTAL && PCI
263 Say Y here if you want to be able to access MMC/SD cards with
264 the Texas Instruments(R) Flash Media card reader, found in many
266 This option 'selects' (turns on, enables) 'TIFM_CORE', but you
267 probably also need appropriate card reader host adapter, such as
268 'Misc devices: TI Flash Media PCI74xx/PCI76xx host adapter support
271 To compile this driver as a module, choose M here: the
272 module will be called tifm_sd.

287 depends on ARCH_DAVINCI
289 This selects the TI DAVINCI Multimedia card Interface.
290 If you have an DAVINCI board with a Multimedia Card slot,
291 say Y or M here. If unsure, say N.
294 tristate "MMC/SD/SDIO over SPI"
295 depends on SPI_MASTER && !HIGHMEM && HAS_DMA
299 Some systems access MMC/SD/SDIO cards using a SPI controller
300 instead of using a "native" MMC/SD/SDIO controller. This has a
301 disadvantage of being relatively high overhead, but a compensating
302 advantage of working on many systems without dedicated MMC/SD/SDIO
305 If unsure, or if your system has no SPI master driver, say N.
308 tristate "Samsung S3C SD/MMC Card Interface support"
309 depends on ARCH_S3C2410

314 slot, say Y or M here.
318 config MMC_S3C_HW_SDIO_IRQ
319 bool "Hardware support for SDIO IRQ"
322 Enable the hardware support for SDIO interrupts instead of using
323 the generic polling code.
326 prompt "Samsung S3C SD/MMC transfer code"
330 bool "Use PIO transfers only"
332 Use PIO to transfer data between memory and the hardware.
334 PIO is slower than DMA as it requires CPU instructions to
335 move the data. This has been the traditional default for
339 bool "Use DMA transfers only (EXPERIMENTAL)"
340 depends on EXPERIMENTAL
342 Use DMA to transfer data between memory and the hardare.
344 Currently, the DMA support in this driver seems to not be
345 working properly and needs to be debugged before this
348 config MMC_S3C_PIODMA
349 bool "Support for both PIO and DMA (EXPERIMENTAL)"
351 Compile both the PIO and DMA transfer routines into the
352 driver and let the platform select at run-time which one
355 See notes for the DMA option.
359 config MMC_SDRICOH_CS
360 tristate "MMC/SD driver for Ricoh Bay1Controllers (EXPERIMENTAL)"
361 depends on EXPERIMENTAL && PCI && PCMCIA
363 Say Y here if your Notebook reports a Ricoh Bay1Controller PCMCIA
364 card whenever you insert a MMC or SD card into the card slot.
366 To compile this driver as a module, choose M here: the
367 module will be called sdricoh_cs.
370 tristate "Toshiba Mobile IO Controller (TMIO) MMC/SD function support"
371 depends on MFD_TMIO || MFD_ASIC3 || SUPERH
373 This provides support for the SD/MMC cell found in TC6393XB,
374 T7L66XB and also HTC ASIC3
377 tristate "ENE CB710 MMC/SD Interface support"
381 This option enables support for MMC/SD part of ENE CB710/720 Flash

401 tristate "Blackfin Secure Digital Host support"
402 depends on MMC && ((BF54x && !BF544) || (BF51x && !BF512))
