Hello Michail setting the register values for PCICLOCK to 25MHz as on the Braswell protectli devices did the trick for me, i have serial working now flawlessly. Did you see the git diff i send ?
I have trouble get superiotool to detect the SUPERIO chip it seems the current version is not even probing for the 8613E.
here is the cpuinfo ( i disabled SMT and SGX in coreboot)

Also please check what is the CPU on your platform. Please run `cat /proc/cpuinfo` and paste me the CPU brand string, because FW6 has refreshed variants based on Kaby Lake Refresh CPUs and different Super I/O ITE8613, which we will upload the source code to upstream coreboot soon.

Hello Michal, i found the regarding problem. The board i got from aliexpress has an SUPERIO 8613 insteat of a SUPERIO 8772F, this other superio seem to be support by coreboot but dumbly changing this in the .config seems to fail, do you think you could help me compiling it for this SUPERIO chip ?
best regards lain
