		NOTE: Some LCD drivers implement an internal framebuffer for
		effeciency reasons but do not export a framebuffer interface.  So

		write graphics data to the LCD device memory, but we cannot read it back.
		If the LCD hardware does not support reading the graphics memory, then

		buffer is 128 * 96 / 2 = 6Kb.  If this is defined, then the driver
		will be fully functional. If not, then it will have the following
		limitations:

		Reading graphics memory cannot be supported, and

		All pixel writes must be aligned to byte boundaries.
		The latter limitation effectively reduces the 128x96 disply to 64x96.

		NOTE: This option should not be used if CONFIG_LCD_FRAMBEBUFFER is
		enabled.  That options provides for a more geneneralized, external
		LCD framebuffer.  This internal framebuffer support should not be
