Technically it will be using mesa even with mali (for libgl), due to
mali-400's only providing opengl es support. But I was more pointing
towards a fail fast for CG parts so that users don't get confused as
to whether they have a device with any opengl hardware support.
Although to be honest I am not sure how useful glx extensions for
Xserver are on a Mali-400 aka ES only device (in comparison to
EGL+glamor).

However the armsoc driver should always be provided since the
DisplayPort interface is available in all zynqmp parts.
