> For your use case, are you interested at all in WP feature? If yes, I am not sure it would work with the strategy of choosing first matching model always.

in 99% of cases, WP is already disabled when doing the initial flash via ChromeOS, but I do use `--wp-status` and `--wp-disable` to be sure.
> If most of chips in this context are new enough to support SFDP, would you consider trying SFDP auto-detection first? Specifically, that's adding -c "SFDP-capable chip" to command line, so that instead of going through the full list flashrom only tries to talk to chip as a generic "SFDP-capable chip"?

I tested this on a few older devices (Haswell, Broadwell, Sany/IvyBridge) and none of them support SFDP, so report chip not found when using the `-c "SFDP-capable chip` param
