1# 2# MMC core configuration 3# 4 5config MMC_UNSAFE_RESUME 6 bool "Allow unsafe resume (DANGEROUS)" 7 help 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. 13 14 This option is usually just for embedded systems which use 15 a MMC/SD card for rootfs. Most people should say N here. 16 17config MMC_EMBEDDED_SDIO 18 boolean "MMC embedded SDIO device support (EXPERIMENTAL)" 19 depends on EXPERIMENTAL 20 help 21 If you say Y here, support will be added for embedded SDIO 22 devices which do not contain the necessary enumeration 23 support in hardware to be properly detected. 24 25config MMC_PARANOID_SD_INIT 26 bool "Enable paranoid SD card initialization (EXPERIMENTAL)" 27 depends on EXPERIMENTAL 28 help 29 If you say Y here, the MMC layer will be extra paranoid 30 about re-trying SD init requests. This can be a useful 31 work-around for buggy controllers and hardware. Enable 32 if you are experiencing issues with SD detection. 33
