Honestly, it's a little bit of cargo culting at this point...
if you search
`git grep 'BOOT_STATE_INIT_ENTRY.*fw_config_handle'`
you will find it used a lot, I think this all started with volteer.

You're not wrong though, it would probably be cleaner to just call from mainboard functions instead of BS entries, especially considering most x86 google mainboards are going to use fw_config to handle GPIOs....

I've also been trying to think of a cleaner way to handle GPIO programming w/r/t fW_config, but haven't come up with anything concrete yet
