Thanks for the information. We are still in the “experimentation” phase 
of this project trying to work out what is the right hardware to use. I 
have looked at the possible BOM cost and it looks like we could swap out 
the SAMA5D2 and replace it with one of the TI AM335x (Beaglebone Black) 
which uses the PowerVR SGX530 GPU.

I posted the same question to the issues on Igalia/meta-webkit at Github 
to try and get some guidance on how I would configure the backend.
