[coreboot] Proper use and intended function of "device pci xx.x on/off" in Config.lb in V2

[bari]

Anyone know how or where in the source "device pci xx.x on/off" is used 
in /mainboard/../../Config.lb ?

In cleaning up the Epia-CN I'm noticing that there are conflicts in 
enables and disables of PCI devices between what is in its Config.lb and 
what is in auto.c, mainboard.c etc. I'm trying to clean this up, but 
almost every board I compare Config.lb files to it's done differently.

I know that many of the boards actually do work, but it is not 
understood how or why it does, only that it does. What board does this 
correctly and is the example that should be followed?
