-config CMDLINE_BOOL
- bool "Built-in kernel command line"
- help
- Allow for specifying boot arguments to the kernel at
- build time. On some systems (e.g. embedded ones), it is
- necessary or convenient to provide some or all of the
- kernel boot arguments with the kernel itself (that is,
- to not rely on the boot loader to provide them.)
-
- To compile command line arguments into the kernel,
- set this option to 'Y', then fill in the
- boot arguments in CONFIG_CMDLINE.
-
- Systems with fully functional boot loaders (i.e. non-embedded)
- should leave this option set to 'N'.
-
-config CMDLINE
- string "Built-in kernel command string"
- depends on CMDLINE_BOOL
- default ""
- help
- Enter arguments here that should be compiled into the kernel
- image and used at boot time. If the boot loader provides a
- command line at boot time, it is appended to this string to
- form the full kernel command line, when the system boots.
-
- However, you can use the CONFIG_CMDLINE_OVERRIDE option to
- change this behavior.
-
- In most cases, the command line (whether built-in or provided
- by the boot loader) should specify the device for the root
- file system.
-
-config CMDLINE_OVERRIDE
- bool "Built-in command line overrides boot loader arguments"
- depends on CMDLINE_BOOL && CMDLINE != ""
- help
- Set this option to 'Y' to have the kernel ignore the boot loader
- command line, and use ONLY the built-in command line.
-
- This is used to work around broken boot loaders. This should
- be set to 'N' under normal conditions.
