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.

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.

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.

The BLOCK TAG trace provides I/O logs for performance analysis and

The trace is default enabled on user and eng builts, say N here to

disable it.
