Hey Nathan,

This machine is supposed to be emulating the ZCU102.

At the moment we only have the EP108 in upstream QEMU. It isn't worth
adding a ZCU102 model upstream yet as at the moment we don't have
enough modeled upstream to notice any differences between the boards.

Hmm... interesting. Thanks for pointing that out.

I don't follow the OE-core mailing list (until yesterday) do you know
if that series is gaining traction?

Thanks,

Alistair
