+          Frame buffer driver for OMAP based boards.

+       help
+         Say Y here, if you want to have support for boards with an
+         external LCD controller connected to the SoSSI/RFBI interface.

+       help
+         Say Y here, if your user-space applications are capable of
+         notifying the frame buffer driver when a change has occured in
+          the frame buffer content and thus a reload of the image data to
+         the external frame buffer is required. If unsure, say N.

+         driver will skip the initialization.

+         Increase the DMA consistent memory size according to your video
+         memory needs, for example if you want to use multiple planes.

+          On systems in which video memory is in system memory
+          (SDRAM) this will speed up graphics DMA operations.
+          If you have such a system and want to use rotation
+          answer yes. Answer no if you have a dedicated video
+          memory, or don't use any of the accelerated features.
