96abaa0c9SPierre Ossman	  If you say Y here, the MMC layer will assume that all cards
106abaa0c9SPierre Ossman	  stayed in their respective slots during the suspend. The
116abaa0c9SPierre Ossman	  normal behaviour is to remove them at suspend and
126abaa0c9SPierre Ossman	  redetecting them at resume. Breaking this assumption will
136abaa0c9SPierre Ossman	  in most cases result in data corruption.
146abaa0c9SPierre Ossman
156abaa0c9SPierre Ossman	  This option is usually just for embedded systems which use
166abaa0c9SPierre Ossman	  a MMC/SD card for rootfs. Most people should say N here.
