1 2config CMDLINE_BOOL 3 bool "Built-in kernel command line" 4 help 5 For most platforms, it is firmware or second stage bootloader 6 that by default specifies the kernel command line options. 7 However, it might be necessary or advantageous to either override 8 the default kernel command line or add a few extra options to it. 9 For such cases, this option allows hardcoding command line options 10 directly into the kernel. 11 12 For that, choose 'Y' here and fill in the extra boot parameters 13 in CONFIG_CMDLINE. 14 15 The built-in options will be concatenated to the default command 16 line if CMDLINE_FORCE is set to 'N'. Otherwise, the default 17 command line will be ignored and replaced by the built-in string. 18 19config CMDLINE 20 string "Built-in kernel command string" 21 depends on CMDLINE_BOOL 22 default "" 23 help 24 Supply command-line options at build time by entering them here. 25 26config CMDLINE_FORCE 27 bool "Built-in command line overrides bootloader arguments" 28 depends on CMDLINE_BOOL 29 help 30 Set this option to 'Y' to have the kernel ignore the bootloader 31 or firmware command line.
