With this config the ep108-zynqmp running on QEMU (mainline one built
by meta-xilinx) is broken, see logbuf below (but it is currently
working fine with the config fragments). Do you know whether this is a
known issue, and if there is a solution? it looks like it is related
to PM, and or lack of PM firmware?

If not I don't think it is worth trying to resolve it at this point,
making the most straight forward way to proceed is to only set this
defconfig for the zcu102 (which I believe is your goal no?). And try
to work out the issues with the defconfig for other machines later?

Regards,
Nathan
