Can you generate this with -M -C? Or just throw

[diff]
        renames = copy

int your git config.

The files are the same right?

No need to have depends on here if the option is hidden. Just make sure
it isn't selected unless the depends are true.

Also, the drivers/firmware/Kconfig file needs to be sourced in the
arch/arm/Kconfig so that we can still get this option on arm (Lina
noticed it isn't working on arm). It looks like arm64 is already
sourcing it.
