bool "Assume MMC/SD cards are non-removable (DANGEROUS)"

help
|
|
If you say Y here, the MMC layer will assume that all cards
|
|
stayed in their respective slots during the suspend. The
|
|
normal behaviour is to remove them at suspend and
|
|
redetecting them at resume. Breaking this assumption will
|
|
in most cases result in data corruption.
|
|
|
|
This option is usually just for embedded systems which use
|
|
a MMC/SD card for rootfs. Most people should say N here.
|
|
|
|
This option sets a default which can be overridden by the
|
|
module parameter "removable=0" or "removable=1".

help
|
|
If you say Y here, support will be added for embedded SDIO
|
|
devices which do not contain the necessary enumeration
|
|
support in hardware to be properly detected.

config MMC_PARANOID_SD_INIT

bool "Enable paranoid SD card initialization (EXPERIMENTAL)"
|

depends on EXPERIMENTAL
|
|
help
|
|
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.
