I did a little searching after sending and I see there's been some patches for mcf5208evb and U-Boot, in QEMU but the last message (2019) was that the CPU emulation wasn't quite complete enough. But yes, one way or another, it would be really great to get a virtualized platform in CI to prevent future breakage. -- Tom
