Ah, this is already great to hear.

I think we're ok to just assume the specific RTC is attached to the i2c
bus then. So your answer is basically "Yes, this is true for a real
MPC8544DS". Awesome.

Right now the code flow is

if (...) {
   foo;
} else {
   bar;
}

where foo is really a special case that doesn't belong into the normal
code flow. Thus I think doing

if (...) {
    foo;
    break;
}

bar;

is more readable.

Also, please make sure to not top post on QEMU mailing lists. We usually
inline responses ;).
