           Say Y here to disable hardware tracing in some known "jumpy" pieces
           of code so that the trace buffer will extend further back.

+          This option enables special console drivers which allow the kernel
+          to print messages very early in the bootup process.

+          This is useful for kernel debugging when your machine crashes very
+          early before the console code is initialized. After enabling this
+          feature, you must add "earlyprintk=serial,uart0,57600" to the
+          command line (bootargs). It is safe to say Y here in all cases, as
+          all of this lives in the init section and is thrown away after the
+          kernel boots completely.
