config CMDLINE_BOOL
	bool "Built-in kernel command line"
	help
	  For most platforms, 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 hardcoding command line options
	  directly into the kernel.

	  For that, choose 'Y' here and fill in the extra boot parameters
	  in CONFIG_CMDLINE.

	  The built-in options will be concatenated to the default command
	  line if CMDLINE_FORCE is set to 'N'. Otherwise, the default
	  command line will be ignored and replaced by the built-in string.

	  Supply command-line options at build time by entering them here.

config CMDLINE_FORCE
	bool "Built-in command line overrides bootloader arguments"
	depends on CMDLINE_BOOL
	help
	  Set this option to 'Y' to have the kernel ignore the bootloader
	  or firmware command line.  Instead, the built-in command line
	  will be used exclusively.

	  If you don't know what to do here, say N.
