What is config_whitelist.txt file and how is it used in u-boot?

In u-boot source code, I see scripts/config_whitelist.txt with many CONFIG_XXX values.
What is the file and how is it used?

Makefile: Give a build error if ad-hoc CONFIG options are added

    The script scripts/check-config.sh will trigger an error during u-boot build if some CONFIG_XXX options are enabled in some include files (Kconfig mechanism should be used instead).
    The file scripts/config_whitelist.txt establishes a list of exceptions to that rule.
