* jffs2_test.sh: this has nothing to do to UBI. And the test is quite trivial,
so it is questionable if it should not be deleted. Anyway, if we want this,
it has to be moved to mtd-utils.git/tests/fs-tests.
+
+* ubigen.c: this utility adds UBI headers to an image file, but does not
+ generate the volume table. It is probably useless, but one might find it
+ interesting, so we do not drop it so far and keep here.
