## Steps to reproduce the issue
Origin: LiteX build for Fomu; in litex-boards/litex_boards/targets/, execute `./kosagi_fomu.py --cpu-variant=minimal --build`
From the attached zip archive: unzip…

In the Fomu workshop, one of the exercises uses LiteX to create a WishBone bus with peripherals (RAM and RGB LED) but _no_ CPU. This is probably a rare situation that is not much tested. It it par…
