* 68000/68328 (Dragonball): these are less capable than the
  68020+ or the Coldfire MCF5xxx line and similar to the 68360
  that was removed in 2016.

I have some patches for the DragonBall series to enable SPI etc there,
some patches to support the SuperVZ variant, some tools to upload
Linux via the integrated serial bootloader.
The DragonBall is probably what anyone that wants to build a 68K retro
computer should use as the DRAM controller is integrated and it can
access 32MB of SDRAM.

Sounds interesting. Do these SoCs come with an MMU? And do they use the
ColdFire instruction set or do they run plain 68k code?

No MMU, plain m68k code.

68328 Soc = 68000 core + some peripherals,
68360 SoC = CPU32 core (based on 68020 + some peripherals.

Anyone working on integrating m68k (and SPARC and MIPS?) softcores in
LiteX? ;-)

when I'm talking to journalists I just say "programmer" or something like that.
