-So basically, we are registering our NAND-specific callbacks with YAFFS
-and registering the RTEMS-YAFFS filesystem callbacks with RTEMS.
-The rtems_filesystem_register() associates the mount() system call with
-a callback function to handle that system call, in this case
-rtems_yaffs_mount_handler(). rtems_yaffs_mount_handler() and
-RTEMS_FILESYSTEM_TYPE_YAFFS (just a string) are provided
-by the rtems-yaffs fork.
-
-mount_and_make_target_path() is provided by RTEMS: it combines a
-mkdir -p` with mount(), passing the mount_args to the
-previously-registered handler.
