Minimal multi-board LED blinker that builds with Yosys (and open tools) and ships ready-to-flash images in GitHub Releases. It is a foray into building Flash Devices across many different boards. While doing so, it was discovered that many older Spartan Boards, UltraScale+ Boards and Cyclone Boards require better flow to bit synthesis support.

Are there other tools I can start using to make this a better template repo for many hardware projects?
