This means we are supporting two separate file system on our embedded
device, one (YAFF/JFFS) for read/write operation on flash and other (FAT) to
have read/write operation on the SD/MMC card i.e multi media operations.
If yes, then for the user space application is not it confusing to have two
separate read/write calls api ?
