We use FPGA_CYCLON2 downstream with devices containing Altera Cyclone
III and IV or Efinix Trion T20 chips.  These are _not_ legacy devices,
few quantities per year, but still produced and sold.

If you need board code to keep the upstream support, I would need
to talk to some people here if we can upstream our board code, or at
least some of it.  That might be difficult though, so if there are
alternatives, please advise.  O:-)
