The H8SCM has serial ports that are routed via the winbond BMC chip 
slash pseudo super I/O, I too have been unable to get output on it.

AFAIK The first is AGESA the second was a port to the native init code, 
however that port no longer works (and I believe neither of them work 
these days)

I believe the simplest way to get started on getting coreboot to work on 
this board is to get a PCI-e serial card that has a serial controller 
matching the model that coreboot supports (I believe the oxford 
OXPCIe952, see the device ID's under generic drivers in menuconfig)
It is what I am going to do when I get the time.
