Freebios2 recovery progress...

[YhLu]

I agree that all onboard device should use the same subsystem id as MB's.

Or more likely src/mainboarod/???/???/Options.lb

src/devices/pci_device.c:pci_dev_enable_resources()
calls dev->ops->pci_ops->set_subsystem() when the device 
dev->on_mainboard is true.  In turn config.g sets that
in static.c for all devices in the static tree.

I believe those are the correct semantics.  That the subsystem is
essentially an identifier for the board the chips are sitting on.

The values are come from:
Look at MAINBOARD_PCI_SUBSYSTEM_VENDOR_ID and MAINBOARD_SUBSYSTEM_DEVICE_ID.

So for the onboard scsi case you likely need to have a driver for
the onboard scsi device that implements the set_subsystem method
because there is not a generic way of doing that.
