For the record, I checked a representative set of the boards to make sure they generate the same .config before and after this change.
Since it's relatively easy to check, I think it's worthwhile to make sure that no .config settings are changed when cleaning up settings.
1. ./util/abuild/abuild -C -a 2. grep CACHE coreboot-builds/*/config.h > before.txt 3. Apply your patch 4. grep CACHE coreboot-builds/*/config.h > after.txt 5. diff before.txt after.txt
abuild -C is "configure-only mode", and runs relatively quickly.
Thanks, Myles
