Virtex5 is only supported by ise/edk, not vivado. This is why the
tools from the last two years does not support ppc.

I think that the position from xilinx was to support ise for as long
as v5, s6... was on sale.

We still use it actively on the fpga family of our productsm and cisco
uses quite a lot of virtex5 :)

Also avnet virtex5 boards are still available

Give me a couple of days and I will be able to answer to that question.

If the patch can wait a bit before it is merged it will be great.

Last change for virtex5 is from 2014.
