+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.
