You can give it a try.  The zynq does have a Cortex-A9 as far as I recall,
so it ought to work.  Doesn't mean there aren't other bits that need
fixing in the zynq specific code.  But maybe there isn't.

Just remember it was never an officially supported kernel version.
It worked for us, it was given a once over by a proper xenomai developer
who did not seem to think it was wrong, but if it doesn't work I wouldn't
expect the xenomai developers to be excited to help fix it.

Well that was a work in progress I believe and never officially released
as far as I recall.  I started from that one, but the one I posted is
actually based on the 3.14 patch and backported as far as I recall.
It has been a while since we moved to 3.14.
