Hi Kevin,
I've attached the console output.

I commented out this code, but other hardware initialization fails, too.
The clock, xhci, ehci, ps2port are not working.
It looks like a generic problem related to inb or outb !

I suggest reporting the problem to the coreboot list - in particular
these lines from coreboot look very suspicious:
