config.sh

#!/usr/bin/env bash

# Usage:
#   build/config.sh <config editor> <make options>*
#
# Example:
#   build/config.sh menuconfig|config|nconfig|... (default to menuconfig)
#
# Runs a configuration editor inside kernel/build environment.
#
# In addition to the environment variables considered in build/build.sh, the
# the following can be defined:
#
#   FRAGMENT_CONFIG
#     If set, the FRAGMENT_CONFIG file (absolute or relative to ROOT_DIR) is
#     updated with the options selected by the config editor.
#
# Note: When editing a FRAGMENT_CONFIG, config.sh is intentionally
#       unintelligent about removing "redundant" configuration options. That is,
#       setting CONFIG_ARM_SMMU=m using config.sh, then unsetting it would
#       result in a fragment config with CONFIG_ARM_SMMU explicitly unset.
#       This behavior is desired since it is unknown whether the base
#       configuration without the fragment would have CONFIG_ARM_SMMU (un)set.
#       If desire is to let the base configuration properly control a CONFIG_
#       option, then remove the line from FRAGMENT_CONFIG
