One can put a Xilinx FPGA on a PCIe card, instantiate a PCIe-AXI bridge and
then use it on any platform that supports PCIe.
I've had to remove this line in order to be able to use the engine on an x86
desktop.
How about plainly removing this "depends on" line and be done with it, instead
of adding platforms one by one?

I agree with you. From my point of view it would be better to remove this line
entirely. I'm just not sure if everyone agrees.
