2 # MMC core configuration
5 config MMC_UNSAFE_RESUME
6 bool "Assume MMC/SD cards are non-removable (DANGEROUS)"
8 If you say Y here, the MMC layer will assume that all cards
9 stayed in their respective slots during the suspend. The
10 normal behaviour is to remove them at suspend and
11 redetecting them at resume. Breaking this assumption will
12 in most cases result in data corruption.
14 This option is usually just for embedded systems which use
15 a MMC/SD card for rootfs. Most people should say N here.
17 This option sets a default which can be overridden by the
18 module parameter "removable=0" or "removable=1".
20 config MMC_EMBEDDED_SDIO
21 boolean "MMC embedded SDIO device support (EXPERIMENTAL)"
22 depends on EXPERIMENTAL
24 If you say Y here, support will be added for embedded SDIO
25 devices which do not contain the necessary enumeration
26 support in hardware to be properly detected.
28 config MMC_PARANOID_SD_INIT
29 bool "Enable paranoid SD card initialization (EXPERIMENTAL)"
30 depends on EXPERIMENTAL
32 If you say Y here, the MMC layer will be extra paranoid
33 about re-trying SD init requests. This can be a useful
34 work-around for buggy controllers and hardware. Enable
35 if you are experiencing issues with SD detection.
