> +# Features that are required by the application but not provided by the BSP

+FEATURES_MISSING = $(sort $(filter-out $(FEATURES_PROVIDED),$(FEATURES_REQUIRED)))
+
+# Features that are only optional and not required at the same time.
+# The policy is to use by default whenever they are provided by the BSP.
+FEATURES_OPTIONAL_ONLY = $(sort $(filter-out $(FEATURES_REQUIRED),$(FEATURES_OPTIONAL)))
+FEATURES_OPTIONAL_USED = $(sort $(filter $(FEATURES_PROVIDED),$(FEATURES_OPTIONAL_ONLY)))
+# Optional features that will not be used because they are unavailable
+FEATURES_OPTIONAL_UNUSED = $(sort $(filter-out $(FEATURES_PROVIDED),$(FEATURES_OPTIONAL_ONLY)))
+
+# Features that are used for an application
+FEATURES_USED = $(sort $(FEATURES_REQUIRED) $(FEATURES_OPTIONAL_USED))
+
+# Used features that conflict when used together
+FEATURES_CONFLICTING = $(sort $(foreach conflict,$(FEATURES_CONFLICT),$(call _features_conflicting,$(conflict))))

The command is `BOARD=slstk3401a make -C tests/periph_rtt/ info-build`

But indeed the `CONFLICTING` seams to be not working, I will check what I am missing.
