> From: Tony Ye <tony.ye at intel.com>
>
> Simple test which exercises the VME fixed function block.
>
> v2: (Tvrtko Ursulin)
> * Small cleanups like copyright date, tabs, remove unused bits.
>
> v3: (Tony Ye)
> * Added curbe data entry for dst surface.
> * Read the dst surface after the VME kernel being executed.
>
> v4: (Tony Ye)
> * Added the media_vme.gxa kernel source code and compile instructions.
>
> v5: (Tvrtko Ursulin)
> * Added hang detector.
