Digging around a bit I think the screen_bits data structure was
originally in a screen.h file that was generated from a screen.xbm file.
That was removed in commit 0c0e6db80683 ("m68k: drop unused parts of
68VZ328 Makefile").
Obviously no one seems to be using this, that has been broken for a long
time now.
I could restore the generated screen.h here, so this could compile at
least. I don't have any of the hardware supported in the arch/m68k/68000
directory, so I can't test anything we fix in there.
The other option is to remove the dragen code altogether.
Regards
Greg
