config MMC_BLOCK
tristate "MMC block device driver"
depends on BLOCK
default y
help
Say Y here to enable the MMC block device driver support.
This provides a block device driver, which you can use to
mount the filesystem. Almost everyone wishing MMC support
should say Y or M here.
config MMC_BLOCK_MINORS
int "Number of minors per block device"
depends on MMC_BLOCK
range 4 256
default 8
help
Number of minors per block device. One is needed for every
partition on the disk (plus one for the whole disk).
Number of total MMC minors available is 256, so your number
of supported block devices will be limited to 256 divided
by this number.
Default is 8 to be backwards compatible with previous
hardwired device numbering.
If unsure, say 8 here.
config SDIO_UART
tristate "SDIO UART/GPS class support"
depends on TTY
help
SDIO function driver for SDIO cards that implements the UART
class, as well as the GPS class which appears like a UART.
config MMC_TEST
tristate "MMC host test driver"
help
Development driver that performs a series of reads and writes
to a memory card in order to expose certain well known bugs
in host controllers. The tests are executed by writing to the
"test" file in debugfs under each card. Note that whatever is
on your card will be overwritten by these tests.
This driver is only of interest to those developing or
testing a host driver. Most people should say N here.
