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.config CMDLINE string "Built-in kernel command string" depends on CMDLINE_BOOL default "" help 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.config EARLY_PRINTK def_bool y
