This worked in the past but won't work in the future when we support devices like tpms. They require a TPM ACPI table. So, we have to dynamically create ACPI tables depending on the bhyve configuration. Bhyve has much more information about the system than OVMF. Therefore, it's easier for bhyve to build up some ACPI tables. For that reason, it would be much better to use the ACPI tables provided by bhyve instead of building some tables by OVMF. At the moment, OVMF always creates a SPCR table. Maybe someone depends on it. So, we have to build it by bhyve too before we can patch OVMF to install the tables provided by bhyve.
