* 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.
