ffsystem.c An example of optional O/S related functions.
Low level disk I/O module is not included in this archive because the FatFs
module is only a generic file system layer and it does not depend on any specific
storage device. You need to provide a low level disk I/O module written to
control the storage device that attached to the target system.
