First, I have been able to apply and build everything fine based on the 
next branch.
It is to be noted that I am using a SabreLite instead of the QMX6, 
therefore I've modified the kernel and bootloader versions.

X is working well just like the graphics. As a FYI, xorg.conf used 
during my testing is coming from Yocto:
https://github.com/Freescale/meta-fsl-arm/blob/master/recipes-graphics/xorg-xserver/xserver-xf86-config/mx6/xorg.conf
Then I've tried to start X, xterm and the Vivante example which are all 
running fine.

There is only one thing I am unclear on which is the Qt5 changes and how 
to test them.
Looking at the configuration it looks like we should have some examples 
installed but I can't seem to run them as I get the following error:
# qmlscene TestCase.qml
Could not initialize GLX
Aborted

I might do something wrong here but it looks like GL isn't configured 
properly. By looking at the configuration again I've realized that we 
have the following option by default:
BR2_PACKAGE_QT5BASE_OPENGL_DESKTOP=y
# BR2_PACKAGE_QT5BASE_OPENGL_ES2 is not set
Where it might make sense to have:
# BR2_PACKAGE_QT5BASE_OPENGL_DESKTOP is not set
BR2_PACKAGE_QT5BASE_OPENGL_ES2=y

Should we specify the QT5BASE_OPENGL_ES2 in the configuration provided 
in your patches or does it behave differently on your side?
Could you send you entire configuration file for comparison?

Thanks,
Gary
