7config MMC_ARMMMCI
8	tristate "ARM AMBA Multimedia Card Interface support"
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.
16
17config MMC_PXA
18	tristate "Intel PXA25x/26x/27x Multimedia Card Interface support"
19	depends on ARCH_PXA
20	help
21	  This selects the Intel(R) PXA(R) Multimedia card Interface.
22	  If you have a PXA(R) platform with a Multimedia Card slot,
23	  say Y or M here.
24
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

68
69	  If unsure, say N.
70
71config MMC_RICOH_MMC
72	tristate "Ricoh MMC Controller Disabler  (EXPERIMENTAL)"
73	depends on MMC_SDHCI_PCI
74	help
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.
81
82
83	  To compile this driver as a module, choose M here:
84	  the module will be called ricoh_mmc.
85
86	  If unsure, say Y.
87
88config MMC_SDHCI_OF

117config MMC_SDHCI_PLTFM
118	tristate "SDHCI support on the platform specific bus"
119	depends on MMC_SDHCI
120	help
121	  This selects the platform specific bus support for Secure Digital Host
122	  Controller Interface.
123
124	  If you have a controller with this interface, say Y or M here.
125
126	  If unsure, say N.
127

129	tristate "SDHCI support on Samsung S3C SoC"
130	depends on MMC_SDHCI && (PLAT_S3C24XX || PLAT_S3C64XX)
131	help
132	  This selects the Secure Digital Host Controller Interface (SDHCI)
133	  often referrered to as the HSMMC block in some of the Samsung S3C
134	  range of SoC.
135
136	  Note, due to the problems with DMA, the DMA support is only
137	  available with CONFIG_EXPERIMENTAL is selected.
138
139	  If you have a controller with this interface, say Y or M here.
140
141	  If unsure, say N.
142
143config MMC_SDHCI_S3C_DMA
144	bool "DMA support on S3C SDHCI"
145	depends on MMC_SDHCI_S3C && EXPERIMENTAL
146	help
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.
150
151	  YMMV.

223	help
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.
228

264	  the Texas Instruments(R) Flash Media card reader, found in many
265	  laptops.
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
269	  (TIFM_7XX1)'.
270
271          To compile this driver as a module, choose M here: the

298	help
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
303	  controllers.

331	help
332	  Use PIO to transfer data between memory and the hardware.
333
334	  PIO is slower than DMA as it requires CPU instructions to
335	  move the data. This has been the traditional default for
336	  the S3C MCI driver.
