soc/intel/alderlake: Skip FSP Notify APIs
Alder Lake SoC deselects Kconfigs as below:
- USE_FSP_NOTIFY_PHASE_READY_TO_BOOT
- USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE
to skip FSP notify APIs (Ready to boot and End of Firmware) and make
use of native coreboot driver to perform SoC recommended operations
prior booting to payload/OS.
Additionally, created a helper function `heci_finalize()` to keep HECI
related operations separated for easy guarding again config.
TODO: coreboot native implementation to skip FSP notify phase API (post
pci enumeration) is still WIP.
BUG=b:211954778
TEST=Able to build brya with these changes and coreboot log with this
code change as below when ADL SoC selects required configs.
BS: BS_PAYLOAD_LOAD run times (exec / console): 135 / 62 ms
coreboot skipped calling FSP notify phase: 00000040.
coreboot skipped calling FSP notify phase: 000000f0.
BS: BS_PAYLOAD_LOAD exit times (exec / console): 0 / 11 ms
Finalizing chipset.
apm_control: Finalizing SMM.
APMC done.
HECI: Sending End-of-Post
CSE: EOP requested action: continue boot
CSE EOP successful, continuing boot
HECI: CSE device 16.1 is disabled
HECI: CSE device 16.4 is disabled
HECI: CSE device 16.5 is disabled
BS: BS_PAYLOAD_BOOT entry times (exec / console): 9 / 27 ms
