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 bool "Ricoh MMC Controller Disabler (EXPERIMENTAL)"
73 depends on MMC_SDHCI_PCI
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.

170 This selects the Secure Digital Host Controller Interface (SDHCI)
171 often referrered to as the HSMMC block in some of the Samsung S3C
174 Note, due to the problems with DMA, the DMA support is only
175 available with CONFIG_EXPERIMENTAL is selected.
177 If you have a controller with this interface, say Y or M here.
182 tristate "Marvell PXA168/PXA910/MMP2 SD Host Controller support"

206 bool "DMA support on S3C SDHCI"
207 depends on MMC_SDHCI_S3C && EXPERIMENTAL
209 Enable DMA support on the Samsung S3C SDHCI glue. The DMA
210 has proved to be problematic if the controller encounters
211 certain errors, and thus should be treated with care.

287 Say Y here to have the Atmel MCI driver use a DMA engine to
288 do data transfers and thus increase the throughput and
289 reduce the CPU utilization. Note that this is highly
290 experimental and may cause the driver to lock up.
295 tristate "Motorola i.MX Multimedia Card Interface support"
298 This selects the Motorola i.MX Multimedia card Interface.
299 If you have a i.MX platform with a Multimedia Card slot,
305 tristate "Qualcomm SDCC Controller Support"
306 depends on MMC && ARCH_MSM

382 config MMC_S3C_HW_SDIO_IRQ
383 bool "Hardware support for SDIO IRQ"
386 Enable the hardware support for SDIO interrupts instead of using
387 the generic polling code.
390 prompt "Samsung S3C SD/MMC transfer code"
394 bool "Use PIO transfers only"
396 Use PIO to transfer data between memory and the hardware.
398 PIO is slower than DMA as it requires CPU instructions to
399 move the data. This has been the traditional default for
403 bool "Use DMA transfers only (EXPERIMENTAL)"
