[coreboot] Kabylake H: SPI Transaction Error at Flash Offset d10000

[Jose Trujillo]

Thank you Christian,

Works in my system too, Kabilake FSP2 issue?
The only small drawback is the disabled ability to upgrade coreboot from itself which correct me if I am wrong is great in terms of security.
Do you know if there is still the possibility to enable HECI to flash SPI in SMM mode even in CHIPSET_LOCKDOWN?
But now this system boots fast.
I owe you one bro.
