		Enable a "front end" that converts an sequential LCD driver into a

		NOTE: Some LCD drivers implement an internal framebuffer for
		effeciency reasons but do not export a framebuffer interface.  So
		those LCD cannot be used as framebuffer drivers.  If the option is

		Define to support external LCD initialization by platform-specific

config LCD_NOGETRUN

		Many LCD hardware interfaces provide only minimal graphics capability.  In

		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
		this option should be defined so that the NX layer can taking alternative
		measures when the LCD is not readable.  For example, if the LCD is not
		readable, then NX will not attempt to support transparency.

		If defined, accesses will be performed
		using an in-memory copy of the OLEDs GDDRAM.  This cost of this
		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
		enabled with CONFIG_LCD_FRAMBEBUFFER because this external commone
		framebuffer interface will provide the necessary buffering.
