It's a parsing error, so it fails on one recipe, and when I remove the recipe, 
some other fails, and so on. After a dozen or so, I gave up.

There's nothing special about the config. Mainly recipes that inherit gitpkgv 
seem affected. I cannot say what triggers it exactly.

Actually, at the moment I don't know how to boot the ZynqMP any more, and the 
Xilinx website isn't helpful either. I can build all the components (FSBL or 
SPL, u-boot, ATF, PMU, kernel, ...) but I have no idea as to how to fit them 
together on a card on in the QSPI flash. The README in meta-xilinx doesn't 
even mention the ZynqMP.
