11 | This is useful for kernel debugging when your machine crashes very | |
12 | early before the console code is initialized. For normal operation | |
13 | it is not recommended because it looks ugly and doesn't cooperate | |
14 | with klogd/syslogd or the X server. You should normally N here, | |
15 | unless you want to debug such a crash. | |

22 | Say Y here to include definitions of printascii, printch, printhex | |

24 | executes before the console is initialized. | |

31 | Say Y here if you want the debug print routines to direct their | |
32 | output to the UniCore On-Chip-Debugger channel using CP #1. | |
