|  | 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. |
