+/*  LCD driver for the Samsung YP-S3
+
+    It appears that this player can contain two display types.
+    Detection of the display type is done by looking at the level of pin P0.4.
+    Currently only display "type 2" has been implemented and tested.
+    
+    This driver could use DMA to do the screen updates, but currently writes
+    the data to the LCD using the processor instead.
