# A note on target vs host configuration:
#
# Host tools can be used across multiple targets, or different configurations
# of the same target. Thus, host tools must be able to handle any combination
# of target configurations. To prevent having different variations of the same
# tool, the tool build options may not depend on target configuration.
#
# Some linux distributions package these utilities as u-boot-tools, and it
# would be unmaintainable to have a different tool variation for each
# arch or configuration.
#
# A couple of simple rules:
#
# 1) Do not use target CONFIG_* options to enable or disable features in host
#    tools. Only use the configs from tools/Kconfig
# 2) It's okay to use target configs to disable building specific tools.
#    That's as long as the features of those tools aren't modified.
#

# Enable all the config-independent tools
