[coreboot] ASUS M4A77TD-PRO. No boot, nothing on the serial port. I'm quite lost.

Ok. I did it and I got the serialICE prompt (@38400). In fact it appears again and
again every second or so. That suggests some watchdog might be rebooting the
board. I already set the it8712f kill watchdog call in coreboot, not sure
if it was needed, but it seems it is. I could put it in serialICE but
unless I need to use SerialICE for something else I think I won't. In fact
if I had done the qemu part coreboot itself might have reset the wachdog
over the serial line, I guess.
Thank you very much. Now I'm going to compare what serialICE does with what
coreboot does and see where I get.
