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

48 Increase the DMA consistent memory size according to your video
49 memory needs, for example if you want to use multiple planes.
50 The size must be 2MB aligned.

55 depends on FB_OMAP
56 help
57 On systems in which video memory is in system memory
58 (SDRAM) this will speed up graphics DMA operations.
59 If you have such a system and want to use rotation
60 answer yes. Answer no if you have a dedicated video
61 memory, or don't use any of the accelerated features.
