> Also, I looked at the FSP EAS v2.4 to find out when FSP-I wants to be called, and I couldn't get any information

It's in Figure 4 API Mode Boot Flow right after the MultiPhaseInit. To coreboot
that'd be one block of things to call without coreboot doing anything in between
(SiliconInit, MultiPhaseInit, SmmInit).

For the API mode, "8.2 Model 2 – FSP owns SMRAM" seems to be the only option.
This would really be a big change for coreboot. So I don't think Gerrit is the
right place to discuss it.
