Coreboot exception on Kabylake xeon-1505v6 and CM238

[roman perepelitsin]

Hi!
I'm trying to exec Coreboot (4.12) on custom board.
Previously,  this board work on 1505v5 (skylake) CPU and coreboot don't
have any problems. But after update CPU - I got exception at
finalizing step.
My 1st  patch - change timeout value in mp_park_aps from 1000 to 3000 - no
effect.
My 2nd patch - I think, that ME didn't work correctly - and I updated it
(no effect).
My 3rd patch - I use me_cleaner.py to disable ME - but exception still
rise.

Maybe someone had similar problems on KBL and have some method fix it?

Log with ME and without ME in attach.
FSP version - latest from intel.

P.S. On coreboot 4.7 I have similar exception, but it rised on CPU#0
initializing.

Thanks!
