 # 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.
 #
