menuconfig MCI
bool "MCI drivers"
select DISK
help
Add support for MCI drivers, used to handle MMC and SD cards
if MCI
comment "--- Feature list ---"
config MCI_STARTUP
bool "Probe on system start"
help
Say 'y' here if the MCI framework should probe for attached MCI cards
on system start up. This is required if the card carries barebox's
environment (for example on systems where the MCI card is the sole
bootmedia). Otherwise probing run on demand with "mci*.probe=1"
config MCI_INFO
bool "MCI Info"
depends on CMD_DEVINFO
default y
help
This entry adds more info about the attached MCI card, when the
'devinfo' command is used on the mci device.
config MCI_WRITE
bool "Support writing to MCI cards"
default y
select DISK_WRITE
config MCI_MMC_BOOT_PARTITIONS
bool "support MMC boot partitions"
comment "--- MCI host drivers ---"
config MCI_DW
bool "Synopsys DesignWare Memory Card Interface"
depends on HAS_DMA
help
This selects support for the Synopsys DesignWare Mobile Storage IP
block, this provides host support for SD and MMC interfaces, in both
PIO and external DMA modes.
config MCI_DW_PIO
bool "Use PIO mode on Synopsys DesignWare MCI"
depends on MCI_DW
help
Use PIO mode (instead of IDMAC) in DW MMC driver.
config MCI_MXS
bool "i.MX23/i.MX28"
depends on ARCH_MXS
help
Enable this entry to add support to read and write SD cards on a
i.MX23/i.MX28 based system.
config MCI_S3C
bool "S3C"
depends on ARCH_S3C24xx
help
Enable this entry to add support to read and write SD cards on a
Samsung S3C24xx based system.
config MCI_BCM283X
bool "MCI support for BCM283X"
depends on ARCH_BCM283X
config MCI_BCM283X_SDHOST
bool "BCM283X sdhost"
depends on ARCH_BCM283X
config MCI_DOVE
bool "Marvell Dove SDHCI"

help
Enable this entry to add support to read and write SD cards on a
Marvell Dove SoC based system.
config MCI_IMX
bool "i.MX"
depends on ARCH_IMX27 || ARCH_IMX31
help
Enable this entry to add support to read and write SD cards on a
Freescale i.MX based system.
config MCI_IMX_ESDHC
bool "i.MX esdhc"
depends on ARCH_IMX || ARCH_LAYERSCAPE
help
Enable this entry to add support to read and write SD cards on a
Freescale i.MX25/35/51 based system.
config MCI_IMX_ESDHC_PIO
bool "use PIO mode"
depends on MCI_IMX_ESDHC
help
mostly useful for debugging. Normally you should use DMA.
config MCI_IMX_ESDHC_PBL
bool
config MCI_OMAP_HSMMC
bool "OMAP HSMMC"
depends on ARCH_OMAP4 || ARCH_OMAP3 || ARCH_AM33XX
help
Enable this entry to add support to read and write SD cards on
both OMAP3 and OMAP4 based systems.
config MCI_PXA
bool "PXA"
depends on ARCH_PXA2XX
help
Enable this entry to add support to read and write SD cards on a
XScale PXA25x / PXA27x based system.
config MCI_ATMEL

help
Enable this entry to add support to read and write SD cards on a
Atmel AT91.
config MCI_MMCI
bool "ARM PL180 MMCI"
depends on ARM_AMBA
help
Enable this entry to add support to read and write SD cards on a
ARM AMBA PL180.
config MCI_TEGRA
bool "Tegra SD/MMC"
depends on ARCH_TEGRA
help
Enable this to support SD and MMC card read/write on a Tegra based
systems.
config MCI_SPI
bool "MMC/SD over SPI"
select CRC7
depends on SPI
help
Some systems access MMC/SD/SDIO cards using a SPI controller
instead of using a "native" MMC/SD/SDIO controller. This has a
disadvantage of being relatively high overhead, but a compensating
advantage of working on many systems without dedicated MMC/SD/SDIO
controllers.
