If we did this for every kernel option we'd get a huge kernel.

In general, we've said that static options for what's needed to boot
to rootfs (i.e. storage and network drivers for nfsroot) are fine to
enable statically.

I doubt you need the EEPROM driver to boot to rootfs on your system,
so please enable it as a module instead.

Look into using config fragments in case you need to modify the
options for local builds, it should be a convenient way to have a
small delta to apply to fit your internal needs, instead of completely
forking the config file.
