10 help
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.

27config MMC_SDHCI
28 tristate "Secure Digital Host Controller Interface support"
29 depends on HAS_DMA
30 help
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.
34
35 If you have a controller with this interface, say Y or M here. You
36 also need to enable an appropriate bus interface.
37
38 If unsure, say N.

58config MMC_RICOH_MMC
59 tristate "Ricoh MMC Controller Disabler (EXPERIMENTAL)"
60 depends on MMC_SDHCI_PCI
61 help
62 This selects the disabler for the Ricoh MMC Controller. This
63 proprietary controller is unnecessary because the SDHCI driver
64 supports MMC cards on the SD controller, but if it is not
65 disabled, it will steal the MMC cards away - rendering them
66 useless. It is safe to select this driver even if you don't
67 have a Ricoh based card reader.
68
69
70 To compile this driver as a module, choose M here:
71 the module will be called ricoh_mmc.
72
73 If unsure, say Y.

146 bool "Atmel MCI DMA support (EXPERIMENTAL)"
147 depends on MMC_ATMELMCI && DMA_ENGINE && EXPERIMENTAL
148 help
149 Say Y here to have the Atmel MCI driver use a DMA engine to
150 do data transfers and thus increase the throughput and
151 reduce the CPU utilization. Note that this is highly
152 experimental and may cause the driver to lock up.

180 help
181 Say Y here if you want to be able to access MMC/SD cards with
182 the Texas Instruments(R) Flash Media card reader, found in many
183 laptops.
184 This option 'selects' (turns on, enables) 'TIFM_CORE', but you
185 probably also need appropriate card reader host adapter, such as
186 'Misc devices: TI Flash Media PCI74xx/PCI76xx host adapter support
187 (TIFM_7XX1)'.

207 select CRC_ITU_T
208 help
209 Some systems access MMC/SD/SDIO cards using a SPI controller
210 instead of using a "native" MMC/SD/SDIO controller. This has a
211 disadvantage of being relatively high overhead, but a compensating
212 advantage of working on many systems without dedicated MMC/SD/SDIO
213 controllers.
214
215 If unsure, or if your system has no SPI master driver, say N.
