Such a large device tree like this is going to be hard to maintain. Is
there overlap between this qemu specific DT and the kernel includes?
if possible it would be very useful to be including what you can from
the zynqmp.dtsi.

Also generally I like to avoid the dtc decompiled devicetrees as they
are hard to read (e.g. phandles are int's, ints are formatted to hex,
etc.). Please try to provide the device tree source(s) if possible.

Alternatively you can also provide this as a blob from the QEMU
sources if that works better? It would allow the tying of QEMU support
to the device tree (aka not having to modify meta-xilinx every time
you modify QEMU bindings). Something similar is used for the
qemumicroblaze machines.

Nathan
