I think it would be better to use the classic m68k stack frame.
That would pave the way for building a single nommu kernel for
MC680[012346]0 that runs on e.g. any Amiga.
MC68000 and Coldfire are incompatible anyway.
While looking at how to do this I realised that the addql #2,%sp in
RESTORE_ALL in entry.h will now break the stack frames for those fancy
68010+ users.
So that needs to be #ifdef'd to make it only compile for 68000. I saw
an error email from the next build stuff so I guess the change has
been queued somewhere? If so I should send a fix..
AFAIK it hasn't been applied yet. These days the bots also test
patches from mailing lists...
I'm not sure how to actually make that generic without patching the
code at runtime (remove the 68000 specific bit, reserve enough extra
space to rewrite the code..) but it's a macro so not so simple.
Or use different entry points depending on CPU type?
