I think AXI counts as a point-to-point link, so no bus.

In my prop-ptr branch you can find some code (untested beyond compilation)
that tried to model AXI using interfaces (git://github.com/pbonzini/qemu.git).
I don't know much about AXI, so I tried to reverse engineer a decent model
from what was done without QOM.
