I am working with CEDAR trail and Crown Bay-like (SYS940X-ECX) systems. For Crown Bay, it is a little confusing to know which tar ball to download. It would be clearer to have one BSP with an option switch to enable the video. 

Also, it would help to know how the EMGD has been configure in the BSP and for what output ports. Having worked with EMGD there are many options. For the SYS940X-ECX, the video driver (VGA-output) doesn't load so X doesn't start. It would be nice to use EMGD to configure this myself and then add the driver, but if this can already be down in the configuration file, it is not clear how to do this.
