adding fw_config will double the number of items in CBI table and make it harder to maintain for factory: https://docs.google.com/spreadsheets/d/11NeXYcg2G-rFmChh2_5T65sJRSYMyPI5/ed…, is it really mandatory for coreboot? if yes , use SSFC for 2nd source should be better

@kylelinck@google.com Hi kyle, Do you have any suggestions? For the current FW_config, due to the particularity of config.star, we have already used a lot of bits. If we add touchpad, it will be difficult to maintain. Can we use ssfc to distinguish?

that is true but it will create ACPI soft device entry. you can assume something like this, if someone is taking this device and booting to OS then they will see many inactive device entries due to redundant ACPI entries

i found multiple touchpads submitted by coreboot, and it seems that none of them use FW_config to probe; and we use different i2c addresses, so it doesn't matter even if we don't distinguish them.
