That is right, but QEMU also has a machine model for the EP108. For
the public sources meta-xilinx has recipes setup to build Linux
(linux-xlnx and linux-yocto, which includes the device tree), U-Boot
(mainline) and ARM Trusted Firmware.

If you were part of the Xilinx early access program and you have
access to a EP108, using the bitstreams and FSBL that are provided
with the board you should be able to boot the built images from
meta-xilinx.

As for general support for ZynqMP, I have been working on updates to
the kernel config fragments (for Zynq as well) to refresh them to work
with newer kernels (and enable more of the kernel drivers for ZynqMP).
I have not merged these to master yet, but will be doing so soon.

I would like to point out though that Xilinx has been doing a great
job up-streaming drivers this time around, the configs in the above
linked config fragment are all available in the upcoming 4.4 kernel.

The ZCU102 looks like the ZC702 for the ZynqMP series. Guess it will
be available when Xilinx starts to ship production silicon. It does
appear that the board has a device tree in the linux-xlnx kernel:
