7config MMC_ARMMMCI

9	depends on ARM_AMBA
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.
14
15	  If unsure, say N.

25	  If unsure, say N.
26
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.
39
40config MMC_SDHCI_IO_ACCESSORS
41	bool
42	depends on MMC_SDHCI
43	help
44	  This is silent Kconfig symbol that is selected by the drivers that
45	  need to overwrite SDHCI IO memory accessors.
46
47config MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER
48	bool
49	select MMC_SDHCI_IO_ACCESSORS
50	help
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.
57
58	  This is the case for the Freescale eSDHC and Nintendo Wii SDHCI.
59
60config MMC_SDHCI_PCI
61	tristate "SDHCI support on PCI bus"
62	depends on MMC_SDHCI && PCI

70
71config MMC_RICOH_MMC
72	bool "Ricoh MMC Controller Disabler  (EXPERIMENTAL)"
73	depends on MMC_SDHCI_PCI
74	help
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.
81
82	  If unsure, say Y.
83
84config MMC_SDHCI_OF

118	  Controller Interface.

128	  This selects the Secure Digital Host Controller Interface (SDHCI)
129	  often referrered to as the HSMMC block in some of the Samsung S3C
130	  range of SoC.
131
132	  Note, due to the problems with DMA, the DMA support is only
133	  available with CONFIG_EXPERIMENTAL is selected.
134
135	  If you have a controller with this interface, say Y or M here.

139config MMC_SDHCI_S3C_DMA
140	bool "DMA support on S3C SDHCI"
141	depends on MMC_SDHCI_S3C && EXPERIMENTAL
142	help
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.
146
147	  YMMV.

220	help
221	  Say Y here to have the Atmel MCI driver use a DMA engine to
222	  do data transfers and thus increase the throughput and
223	  reduce the CPU utilization. Note that this is highly
224	  experimental and may cause the driver to lock up.

261	  the Texas Instruments(R) Flash Media card reader, found in many
262	  laptops.
263	  This option 'selects' (turns on, enables) 'TIFM_CORE', but you
264	  probably also need appropriate card reader host adapter, such as
265	  'Misc devices: TI Flash Media PCI74xx/PCI76xx host adapter support
266	  (TIFM_7XX1)'.

296	  Some systems access MMC/SD/SDIO cards using a SPI controller
297	  instead of using a "native" MMC/SD/SDIO controller.  This has a
298	  disadvantage of being relatively high overhead, but a compensating
299	  advantage of working on many systems without dedicated MMC/SD/SDIO

329	  Use PIO to transfer data between memory and the hardware.
