Can I ask you to reconsider? We, for example, don't make any use of the
Xilinx dev tools to generate our device trees. Having a dtsi allows for
easy extension of the zynq-7000 platform for our boards, without having
to carry duplicate data.
Is it going to be expected that users building kernels for their zynq
targets have access to the Xilinx EDK?

You're likely running into the issue Nick has identified in the thread
for patch 5 where the chosen virtual address for the uart doesn't seem
to work: http://www.spinics.net/lists/arm-kernel/msg203141.html
We haven't yet identified the root cause; any insight you can provide
here would be beneficial.
Otherwise, I'm considering reworking patch 5 to move the uart mapping to
a known working location.
