You can get an empty machine with "-M none" nowadays, so the
m68k dummy board (introduced in 2007) seems to be pretty
redundant since the "none" machine has been added in 2012.

I'm not sure the "none" machine can replace the "dummy" machine as the
"dummy" machine can load a kernel whereas it seems the "none" one can't.

Oh, that's true ... I did not notice it 'cause there was no error
message when I tried to start the "none" machine with "-kernel". But
looking at the code in hw/core/null-machine.c, it really seems that
there is nothing in here :-( So never mind, please forget about this
patch. (but now I wonder whether the "none" machine could be improved to
provide the features of the "dummy" machine, too?)

The "none" machine is defined to be be filled with QMP commands, perhaps
the generic-loader object can replace the "-kernel" parameters?
