Apart from the comments on patch 2/3 everything looks good.

It looks like Robert is close to merging the runqemu rewrite (his
branch of oe is here:
http://cgit.openembedded.org/openembedded-core-contrib/log/?h=rbt/runqemu).
So I had a play to see if I can get the zcu102-zynqmp machine using
that with the qemu-xilinx, it works quite well. I have a
work-in-progress branch here:

It doesn't get past here, which is expected since its trying to run
the kernel instead of u-boot. But this shows that with the new runqemu
there is no need to duplicate the runqemu script in meta-xilinx which
is great.

Also with the "qemuboot.py" it looks like it might be easy to have
qemuboot.py and qemuboot-mainline.py (or default mainline and
qemuboot-xilinx.py) for ep108 to allow for easy execution of either
version.

Nathan
