+	help
+	  Valgrind is an instrumentation framework for building dynamic analysis

+	  in U-Boot. It relies on knowing when heap blocks are allocated in
+	  order to give accurate results. This happens automatically for
+	  standard allocator functions provided by the host OS. However, this
+	  doesn't automatically happen for U-Boot's malloc implementation.
