Hi,
The UART is described in the Zynq TRMs, I think you can just
google for zynq TRM and a reference to UG585 and UG1085 will come up.
http://www.xilinx.com/support/documentation/user_guides/ug585-Zynq-7000-TRM.pdf
http://www.xilinx.com/support/documentation/user_guides/ug1085-zynq-ultrascale-trm.pdf
AFAIK, the ZynqMP has a newer version of the cadence UART with a superset of
the feature set. I don't think QEMU models any of the differences though.
Cheers,
Edgar
