I meant out of the machines that are currently supported in the kernel.
As far as I can tell, the only 68000 variants that are supported are
all Dragonball CONFIG_M68328, CONFIG_M68EZ328 and
CONFIG_M68VZ328.

CONFIG_MCPU32 has been dead since a3595962d824 ("m68knommu:
remove obsolete 68360 support")
