-OMAP FB allocates the framebuffer memory using the OMAP VRAM allocator.
+OMAP FB allocates the framebuffer memory using the standard dma allocator. You
+can enable Contiguous Memory Allocator (CONFIG_CMA) to improve the dma
+allocator, and if CMA is enabled, you use "cma=" kernel parameter to increase
+the global memory area for CMA.
 
 Using DSI DPLL to generate pixel clock it is possible produce the pixel clock
 of 86.5MHz (max possible), and with that you get 1280x1024@57 output from DVI.
