Essential is "needed to configure machine to load Linux". Which really
means that devices for it exist in the device tree, and those devices
need to run some code to make the node boot.

Those are northbridge register on k8 and on a 2-cpu system you need
them. But do you need them in Config.lb? You know, I just realized, I
don't know :-)

Even disabled, they are still in the static tree. I am saying to not
even list pci devices (particularly slots) if they are not needed to
configure the platform for linuxbios. In many, many cases, all you
need are the IO APIC, the superio, the CPU, and that's it. We have
poor documentation and as a result people tend to put more in
config.lb thany they need.
