Last time I talked with GK802 guys they were working in porting it to
U-Boot mainline; I have made the patches here to integrate it to
meta-fsl-arm-extra a while ago but I am awaiting for their U-Boot
patch. I am attaching the three patches for reference anyway.

I think you should focus in get it booting and working, initially,
with core-image-base and then move to more complex use-cases like
systemd afterwards.

Please check the patches I attached to see if they help in something.
