It does not apply without the preceding patches. Here's my cherry-pick
result:

I.e. we might change 1 -> 4 in the SysBus API, but would that work given
that endianness is being changed alongside?
If either of you could submit a version limited to bug fixes or explain
why the whole refactoring is needed as bug fix and provide a bisectable
version, I can certainly apply it for -rc1 if my test cases continue
working.
BTW another unresolved issue that's been discussed is whether we should
change the default CPU for -M prep. I've been open to doing so for 2.0
but would like some pointer that such a machine did exist rather than
just happens to work better with OpenBIOS.
Regards,
Andreas
