3 # A wrapper script to adjust Kconfig for U-Boot
5 # Instead of touching various parts under the scripts/kconfig/ directory,
6 # pushing necessary adjustments into this single script would be better
7 # for code maintainance. All the make targets related to the configuration
8 # (make %config) should be invoked via this script.
9 # See doc/README.kconfig for further information of Kconfig.
