14   The LCD Controller (LCDC) consists of logic for transferring LCD image data
15   from an external display buffer to a TFT LCD panel. The LCDC has one display
17   interface and a look-up table to allow palletized display configurations. The
18   LCDC is programmable on a per layer basis, and supports different LCD
