Do you see any other messages at all from a cold start (i.e. AC power
removed from the system, then reapplied after 15 seconds while the
serial console is being logged)?

I have not personally tested the 8M chips; it could be that there is an
issue with coreboot's generic driver for those devices.  I know it's not
a general issue with large Flash chips since the 16M chips work fine.

Thanks!
