Do you have a roadmap for the following steps? Or are you done with
this series?

Yesterday I was thinking about this, and one thing I was wondering is
if it would be possible to have DeviceClass and MachineClass implement
a populate_fdt() handler, to automatically generate custom DTB for these
custom machines.

Maybe in your case you don't need that, as your framework generating the
QEMU machine also generates the DTB, or even parse a DTB to generate the
machine... :)

Phil.
