Have you looked at device paths generated by get_fw_dev_path() in qdev?
This function generates Open Firmware device path. The difference
between OF device path and the examples above is that OF device path has
a meaning outside of QEMU and can be used by firmware to find a device
a path refers too. Will QOM be able to generate them?

The paths look like:
/address@hidden/address@hidden,1/address@hidden/address@hidden
/address@hidden/address@hidden/address@hidden/address@hidden
/address@hidden/address@hidden/address@hidden/address@hidden
/address@hidden/address@hidden,1/address@hidden/address@hidden
/address@hidden/address@hidden,1/address@hidden/address@hidden
/address@hidden/address@hidden/address@hidden,0
/address@hidden/address@hidden/address@hidden
/address@hidden/address@hidden/address@hidden
/address@hidden/address@hidden,1/address@hidden/address@hidden
/address@hidden/address@hidden/address@hidden/address@hidden/address@hidden
/address@hidden/address@hidden,2/address@hidden/address@hidden
/address@hidden/address@hidden,2/address@hidden/address@hidden/address@hidden
/address@hidden/linuxboot.bin

For isa machines:
/isa/address@hidden/address@hidden/address@hidden
/isa/address@hidden/address@hidden
/isa/address@hidden/address@hidden
/isa/address@hidden/address@hidden/address@hidden
