6 months seems long but I ready for that challenge :-) its
a good chance to become familiar with the PC architecture.
displaying logs only, took me 2 weeks so I'm prepared for that.

ok, the EC is a M38857 chip (Renesas M3885 family)
I don't know the board connections of it but I have a
multimeter and a oscilloscope - so maybe I while
figure it out in the future :-)

What's the next line if you don't boot that kernel with coreboot?

Also, a full log might help...
