- bool "Built-in kernel command line"
- 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.

-config CMDLINE
- string "Default kernel command string"
- depends on CMDLINE_BOOL
- 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
- bool "Built-in command line overrides firmware arguments"
- 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.
