+/*-
  * Device driver to export the SRAM frame buffer (and other parts) for the
  * Terasic MTL-LCD part, hooked up to the processor via a memory-mapped Avalon
  * bus.
+ *
+ * TODO:
+ *
+ * 1. Allow read(2) and write(2) to work on MTL frame buffer / input memory so
+ *    that dd(1), etc, can be used to paint the touch screen conveniently
+ *    when there is no windowing system running.
+ *
+ * 2. Allow different portions of the MTL memory space to be exported via
+ *    different device nodes -- text frame buffer, graphics frame buffer,
+ *    touch screen input.
+ *
+ * 3. Teach syscons(4) about the text frame buffer.
