	  Number of framebuffers to allocate in ELCDIF driver. Driver allocated
	  framebuffers are required to support partial display updates.
	  The driver has been validated to support 0 through 2 framebuffers.
	  Note that hardware will likely perform best if zero driver
	  framebuffers are allocated by the driver, and the application
	  implements double framebuffering by always calling display_write with
	  a buffer equal in size to the connected panel.

	  NOTE: when no framebuffers are allocated, the ELCDIF will be
	  set to display an empty buffer during initialization. This means
	  the display will show what is effectively a dump of
	  system RAM until a new framebuffer is written. If the security
	  implications of this concern you, leave at least one driver
	  framebuffer enabled.
