+       help
+         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. For normal operation,
+         it is not recommended because it looks ugly on some machines and
+         doesn't cooperate with an X server. You should normally say N here,
+         unless you want to debug such a crash.
+
+config CMDLINE_BOOL
+       bool "Built-in kernel command line"
+       default n
+       help
+         For most systems, it is firmware or second stage bootloader that
+         by default specifies the kernel command line options.  However,
+         it might be necessary or advantageous to either override the
+         default kernel command line or add a few extra options to it.
+         For such cases, this option allows you to hardcode your own
+         command line options directly into the kernel.  For that, you
+         should choose 'Y' here, and fill in the extra boot arguments
+         in CONFIG_CMDLINE.
+
+         The built-in options will be concatenated to the default command
+         line if CMDLINE_OVERRIDE is set to 'N'. Otherwise, the default
+         command line will be ignored and replaced by the built-in string.
+
+         Most MIPS systems will normally expect 'N' here and rely upon
+         the command line from the firmware or the second-stage bootloader.

          On some platforms, there is currently no way for the boot loader to
-         pass arguments to the kernel. For these platforms, you can supply
-         some command-line options at build time by entering them here.  In
-         other cases you can specify kernel args so that you don't have
-         to set them up in board prom initialization routines.
+         pass arguments to the kernel.  For these platforms, and for the cases
+         when you want to add some extra options to the command line or ignore
+         the default command line, you can supply some command-line options at
+         build time by entering them here.  In other cases you can specify

+       help
+         By setting this option to 'Y' you will have your kernel ignore
+         command line arguments from firmware or second stage bootloader.
+         Instead, the built-in command line will be used exclusively.
+
+         Normally, you will choose 'N' here.
