# 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.
