This selects Hardware reset support aka pwrseq-emmc for eMMC
|
|
devices. By default this option is set to y.

This driver can also be built as a module. If so, the module
|

will be called pwrseq_emmc.

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.

This option is support deferred resume on card.

when there are the first I/O after the resume operation,
|
|
card initialization eventually starts for saving resume time.

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.

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.

If you say Y here, the MMC layer will be extra paranoid
|
|
about re-trying SD init requests. This can be a useful
|
|
work-around for buggy controllers and hardware. Enable

if you are experiencing issues with SD detection.
