6# A note on target vs host configuration:
7#
8# Host tools can be used across multiple targets, or different configurations
9# of the same target. Thus, host tools must be able to handle any combination
10# of target configurations. To prevent having different variations of the same
11# tool, the tool build options may not depend on target configuration.
12#
13# Some linux distributions package these utilities as u-boot-tools, and it
14# would be unmaintainable to have a different tool variation for each
15# arch or configuration.
16#
17# A couple of simple rules:
18#
19# 1) Do not use target CONFIG_* options to enable or disable features in host
20# tools. Only use the configs from tools/Kconfig
21# 2) It's okay to use target configs to disable building specific tools.
22# That's as long as the features of those tools aren't modified.
23#
24
25# Enable all the config-independent tools
