PS4, Line 242: verstage_soc_init
> Hrmm, it's strange that verstage_soc_init gets called before `verstage_mainboard_early_init`.

Indeed. verstage_soc_init does espi setup, which is needed for the later steps. I could breakup verstage_soc_init a bit, e.g. espi_soc_early_init and i2c_soc_early_init.
