That's great to hear. While I started my life on m68k machines, I never
did get Linux up on one. Do the coldfire platforms you have run U-Boot
today? If so, are they already supported upstream? One of my biggest
concerns about the architecture, in U-Boot, is that I've just not heard
of anyone using it in quite some time, and we don't have any emulated
platforms either (can it be done in QEMU? We have other plaforms in CI
via QEMU) so I worry it's not working.
Qemu supports both m68k and ColdFire nowadays:

PS. For m68k there are also a lot of other emulators that emulate
specific platforms.
Aranym, 68040 Atari "clone", used a lot by Debian m68k port before Qemu
got m68k support.
WinAUE, 68000-68040 Amiga emulation. Unlike Aranym or Qemu, this
emulates also CPU cache.
Hatari, 68000-68040 Atari emulation (based on WinUAE CPU core).
Previous, 68030 NeXT emulator (based on Hatari).
But none of the platforms listed above boot using U-Boot, which is
what Tom is interested in...
"qemu-system-m68k -machine help" lists a.o.:
an5206 Arnewsh 5206
mcf5208evb MCF5208EVB (default)
U-Boot still contains include/configs/M5208EVBE.h, but there are no
actual users...
Angelo: so support for amcore in qemu would be nice ;-)
Thanks!
Gr{oetje,eeting}s,
