what Michael referred to as duplication is probably these lines,
however "smbios-entry-point-type: is machine property so we can't
use device compat machinery here (pc_compat_8_0).
What we can do is override "default_machine_opts" value, but then
again it has to be opencoded in  piix4/q35_machine_options, so
don't see a point in doing so.
As you wrote here is what typically do for machine compat knobs,
so it should be fine.

Ok

I just doubt that we need extra default_smbios_ep_type field.

I introduce pcmc->default_smbios_ep_type because I could not get to pcms->smbios_entry_point_type from these functions. Any suggestions?

Anyhow, I'll send out v5 with some more clean up.

Thanks,
Suravee
