            # 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

            # 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.

	# 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.
	#
