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.

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_PCI
48	tristate "SDHCI support on PCI bus"
49	depends on MMC_SDHCI && PCI
50	help
51	  This selects the PCI Secure Digital Host Controller Interface.
52	  Most controllers found today are PCI devices.
53
54	  If you have a controller with this interface, say Y or M here.
55
56	  If unsure, say N.
57
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.
74
75config MMC_SDHCI_OF
76	tristate "SDHCI support on OpenFirmware platforms"
77	depends on MMC_SDHCI && PPC_OF
78	select MMC_SDHCI_IO_ACCESSORS
79	help
80	  This selects the OF support for Secure Digital Host Controller
81	  Interfaces. So far, only the Freescale eSDHC controller is known
82	  to exist on OF platforms.
83
84	  If unsure, say N.
85
86config MMC_SDHCI_PLTFM
87	tristate "SDHCI support on the platform specific bus"
88	depends on MMC_SDHCI
89	help
90	  This selects the platform specific bus support for Secure Digital Host
91	  Controller Interface.
92
93	  If you have a controller with this interface, say Y or M here.
94
95	  If unsure, say N.
96

98	tristate "SDHCI support on Samsung S3C SoC"
99	depends on MMC_SDHCI && (PLAT_S3C24XX || PLAT_S3C64XX)
100	help
101	  This selects the Secure Digital Host Controller Interface (SDHCI)
102	  often referrered to as the HSMMC block in some of the Samsung S3C
103	  range of SoC.
104
105	  Note, due to the problems with DMA, the DMA support is only
106	  available with CONFIG_EXPERIMENTAL is selected.
107
108	  If you have a controller with this interface, say Y or M here.
109
110	  If unsure, say N.
111
112config MMC_SDHCI_S3C_DMA
113	bool "DMA support on S3C SDHCI"
114	depends on MMC_SDHCI_S3C && EXPERIMENTAL
115	help
116	  Enable DMA support on the Samsung S3C SDHCI glue. The DMA
117	  has proved to be problematic if the controller encounters
118	  certain errors, and thus should be treated with care.
119
120	  YMMV.

126	help
127	  This selects the TI OMAP Multimedia card Interface.
128	  If you have an OMAP board with a Multimedia Card slot,
129	  say Y or M here.
130
131	  If unsure, say N.
132
133config MMC_OMAP_HS
134	tristate "TI OMAP High Speed Multimedia Card Interface support"

192	help
193	  Say Y here to have the Atmel MCI driver use a DMA engine to
194	  do data transfers and thus increase the throughput and
195	  reduce the CPU utilization. Note that this is highly
196	  experimental and may cause the driver to lock up.
197
198	  If unsure, say N.
199
200config MMC_IMX
201	tristate "Motorola i.MX Multimedia Card Interface support"
202	depends on ARCH_MX1
203	help
204	  This selects the Motorola i.MX Multimedia card Interface.
205	  If you have a i.MX platform with a Multimedia Card slot,
206	  say Y or M here.
207
208	  If unsure, say N.
209
210config MMC_MSM7X00A
211	tristate "Qualcomm MSM 7X00A SDCC Controller Support"
212	depends on MMC && ARCH_MSM

231	help
232	  Say Y here if you want to be able to access MMC/SD cards with
233	  the Texas Instruments(R) Flash Media card reader, found in many
234	  laptops.
235	  This option 'selects' (turns on, enables) 'TIFM_CORE', but you
236	  probably also need appropriate card reader host adapter, such as
237	  'Misc devices: TI Flash Media PCI74xx/PCI76xx host adapter support
238	  (TIFM_7XX1)'.
239
240          To compile this driver as a module, choose M here: the

256	depends on SPI_MASTER && !HIGHMEM && HAS_DMA
257	select CRC7
258	select CRC_ITU_T
259	help
260	  Some systems access MMC/SD/SDIO cards using a SPI controller
261	  instead of using a "native" MMC/SD/SDIO controller.  This has a
262	  disadvantage of being relatively high overhead, but a compensating
263	  advantage of working on many systems without dedicated MMC/SD/SDIO
264	  controllers.
265
266	  If unsure, or if your system has no SPI master driver, say N.

291	bool "Use PIO transfers only"
292	help
293	  Use PIO to transfer data between memory and the hardware.
294
295	  PIO is slower than DMA as it requires CPU instructions to
296	  move the data. This has been the traditional default for
297	  the S3C MCI driver.
298

300	bool "Use DMA transfers only (EXPERIMENTAL)"
301	depends on EXPERIMENTAL
302	help
303	  Use DMA to transfer data between memory and the hardare.
304
305	  Currently, the DMA support in this driver seems to not be
306	  working properly and needs to be debugged before this
307	  option is useful.
308
309config MMC_S3C_PIODMA
