+          boundary. However, if they are aligned on different boundaries

+        help
+          Allows the editing of auto-generated platform settings from
+          the Kconfig.auto file. Obviously this does not change the
+          underlying hardware, so be very careful if you go editing
+          these settings.
+
+          Also, if you enable this, and edit various Kconfig.auto
+          settings, YOUR CHANGES WILL BE LOST if you then disable it
+          again. You have been warned!
+
+          If unsure, say no.
