+ * Name:  stm3210e_lcdclear
+ *
+ * Description:
+ *   This is a non-standard LCD interface just for the STM3210E-EVAL board.  Because
+ *   of the various rotations, clearing the display in the normal way by writing a
+ *   sequences of runs that covers the entire display can be very slow.  Here the
+ *   dispaly is cleared by simply setting all GRAM memory to the specified color.
