+        help
+          When using multi-CPU chips it is possible for U-Boot to start up
+          more than one CPU. The stack memory used by all of these CPUs is
+          pre-allocated so at present U-Boot wants to know the maximum
+          number of CPUs that may be present. Set this to at least as high
+          as the number of CPUs in your system (it uses about 4KB of RAM for
+          each CPU).

+	  Enable use of more than one CPU in U-Boot and the Operating System
+	  when loaded. Each CPU will be started up and information can be

+	  the memory used by this initialisation process. Typically 4KB is
