/* Uncomment the following lines if you want to use multiple displays on
* different controllers.
/* You must either define GDISP_TOTAL_DISPLAYS or GDISP_DRIVER_LIST for multiple displays.
* You cannot define both!
*
* Change the definitions to suit your hardware.
* Currently all controllers must use the same pixel format.
* Defining GDISP_TOTAL_DISPLAYS will create multiple instances of the one default driver.
* Defining GDISP_DRIVER_LIST allows you to specify multiple different drivers.
*
* Remember that GDISP_TOTAL_DISPLAYS above must match the **Total**
* number of displays in your system across all controllers.
* Extra Notes for GDISP_DRIVER_LIST:
*-----------------------------------
*
* The same controller can appear more than once in the list.
*
* You must specify a GDISP_PIXELFORMAT that the application will work in. This
* is translated into each drivers internal pixel format by the driver. You the
* pixel format that is most common accross your drivers (for efficiency).
*
* Optionally, you can also specify hardware characteristics that are common to
* all your controllers. This significantly improves code and speed efficiency
