|  | Say Y here if you are compiling the kernel on a different | 
|  | architecture than the one it is intended to run on.  This is just a | 
|  | convenience option which will select the appropriate value for | 
|  | the CROSS_COMPILE make variable which otherwise has to be passed on | 
|  | the command line from mips-linux-, mipsel-linux-, mips64-linux- and | 
|  | mips64el-linux- as appropriate for a particular kernel configuration. | 
|  | You will have to pass the value for CROSS_COMPILE manually if the | 
|  | name prefix for your tools is different. |

|  | help | 
|  | On some platforms, there is currently no way for the boot loader to | 
|  | pass arguments to the kernel. For these platforms, you can supply | 
|  | some command-line options at build time by entering them here.  In | 
|  | other cases you can specify kernel args so that you don't have | 
|  | to set them up in board prom initialization routines. |

|  | help | 
|  | If you say Y here, it will be possible to remotely debug the MIPS | 
|  | kernel using gdb. This enlarges your kernel image disk size by | 
|  | several megabytes and requires a machine with more than 16 MB, | 
|  | better 32 MB RAM to avoid excessive linking time. This is only | 
|  | useful for kernel hackers. If unsure, say N. |

|  | If you are using GDB for remote debugging over a serial port and | 
|  | would like kernel messages to be formatted into GDB $O packets so | 
|  | that GDB prints them as program output, say 'Y'. |

|  | help | 
|  | If you say Y here, some debugging macros will do run-time checking. | 
|  | If you say N here, those macros will mostly turn to no-ops.  See | 
|  | include/asm-mips/debug.h for debuging macros. |

|  | help | 
|  | If you say Y here there kernel will disable all CPU caches.  This will | 
|  | reduce the system's performance dramatically but can help finding | 
|  | otherwise hard to track bugs.  It can also useful if you're doing | 
|  | hardware debugging with a logic analyzer and need to see all traffic | 
|  | on the bus. |
