+         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.

+         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.

+       help
+         On some platforms, there is currently no way for the boot loader to
+         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
+         kernel args so that you don't have to set them up in board prom
+         initialization routines.
+
+         For more information, see the CMDLINE_BOOL and CMDLINE_OVERRIDE
+         options.

+config CMDLINE_OVERRIDE

+       default n
+       depends on CMDLINE_BOOL
+       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.

+       help
+         If you say Y here, some debugging macros will do run-time checking.
+         If you say N here, those macros will mostly turn to no-ops.  See
+         arch/mips/include/asm/debug.h for debugging macros.
+         If unsure, say N.

+       default n
+       help
+         If you want to add compressed kernel support to a new board, and the
+         board supports uart16550 compatible serial port, please select
+         SYS_SUPPORTS_ZBOOT_UART16550 for your board and enable this option to
+         debug it.
+
+         If your board doesn't support uart16550 compatible serial port, you
+         can try to select SYS_SUPPORTS_ZBOOT and use the other methods to
+         debug it. for example, add a new serial port support just as
+         arch/mips/boot/compressed/uart-16550.c does.
+
+         After the compressed kernel support works, please disable this option
+         to reduce the kernel image size and speed up the booting procedure a
