+# Helper for self-extracting binaries distributed by Freescale.
+# The --force makes sure it doesn't fail if the source dir already exists.
+# The --auto-accept skips the license check - not needed for us
+# because we have legal-info
+# Since there's a EULA in the bin file, extract it
+# If you use this macro, don't forget to add "EULA" to LICENSE_FILES and set
+# REDISTRIBUTE to "NO". Indeed, this is a legal minefield:
+# the EULA specifies that the Board Support Package includes software
+# and hardware (sic!) for which a separate license is needed...
