+      If your architecture has an MMU and you want to use it,
+      say 'Y' here.
+      
+      OTOH, if you don't want to use the MMU, or your arch
+      lacks an MMU, say 'N' here.
+      
+      Note that some architectures (eg. ARM) has variants that
+      lacks an MMU (eg. ARM Cortex-M3), while other variants
+      have one (eg. ARM Cortex-A8).
