PS1, Line 251: #if CONFIG(SOC_INTEL_COMMON_BLOCK_SMM_LOCK_GPIO_PADS)
> Are you suggesting we shouldn't need the guard at all for the locking feature, or just that we don't […]

Yes, once you add a weak soc_gpio_lock_config override, you dont need this guard. Even if ADL disables CONFIG(SOC_INTEL_COMMON_BLOCK_SMM_LOCK_GPIO_PADS), things will compile and work as expected.

```
if (CONFIG(SOC_INTEL_COMMON_BLOCK_SMM_LOCK_GPIO_PADS))
    soc_lock_gpio();
```

The above snippet of code in smihandler.c in the previous CL will ensure that the GPIOs are locked at run-time if the config is enabled and stay unlocked if it is disabled.

The code to lock GPIO config and the associated mainboard/soc GPIO tables are always compiled into coreboot.
