Hi Emily,

You can use something like this
https://github.com/Xilinx/meta-xilinx/blob/rel-v2018.2/meta-xilinx-bsp/conf/machine/include/machine-xilinx-default.inc#L32-L36

The above can be used from master/sumo branch.

This hasn't been added yet to master, note that not all variants of FPGA 
support MALI 400 GPU.
I will send a patch this week to update the defaults using the override 
mechanism.

Thanks,
Manju
