Re: [coreboot] Kabylake unable to boot with post code 0x71 "SGX: pre-conditions not met"

[Naresh G. Solanki]

Hi
> PCH: device id a152 (rev 31) is Unknown

This indicates that LPCID 0xa152 is not added.

The #define should be added in source path:
https://review.coreboot.org/cgit/coreboot.git/tree/src/include/device/pci_id...

https://review.coreboot.org/cgit/coreboot.git/tree/src/soc/intel/common/bloc...

&

https://review.coreboot.org/cgit/coreboot.git/tree/src/soc/intel/skylake/boo...

as well.

Additionally you can enable config DEBUG_BOOT_STATE to understand
where exactly its stuck.
