-       help
-         This option select the standard 4kB Linux page size.  On some
-         R3000-family processors this is the only available page size.  Using
-         4kB page size will minimize memory consumption and is therefore
-         recommended for low memory systems.

-         only on cnMIPS processors.  Note that you will need a suitable Linux
