PS1, Line 28: if (CONFIG(VBOOT_STARTS_BEFORE_BOOTBLOCK)) {
            : 		enable_aoac_devices();
            : 		printk(BIOS_DEBUG, "Setting up i2c\n");
            : 		i2c_soc_early_init();
            : 		printk(BIOS_DEBUG, "i2c setup\n");
            : 	}
I think this should be done as part of `verstage_soc_init()` and not mainboard init. It is similar to how i2c early init and other inits are performed in bootblock and/or other stages.
