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