The original idea was to boot into Linux (hence LinuxBIOS, back in the day). coreboot is very different from this scheme, see the presence of payloads that aren't Linux.

The only option I see for getting rid of PCI support on ARM is to remodel the relationships between coreboot, the payload and the OS. Reminds me that I wanted to build a proof-of-concept for chainloaded payloads, a concept that might help with such a redesign because we could move things out of coreboot to "elsewhere" (wherever that might be) piece by piece. But as is, if there are PCI(e) devices that need early init, coreboot is the place to put these drivers.
