  9           If this option is disabled, you allow userspace (root) access to all
 10           of memory, including kernel and userspace memory. Accidental
 11           access to this is obviously disastrous, but specific access can
 12           be used by people debugging the kernel.
 13 
 14           If this option is switched on, the /dev/mem file only allows
 15           userspace access to memory mapped peripherals.

 17           If in doubt, say Y.

 22           Write kernel log output directly into the ocd or to a serial port.
 23 
 24           This is useful for kernel debugging when your machine crashes very
 25           early before the console code is initialized. For normal operation
 26           it is not recommended because it looks ugly and doesn't cooperate
 27           with klogd/syslogd or the X server. You should normally N here,
 28           unless you want to debug such a crash.

 35           Say Y here to include definitions of printascii, printch, printhex
 36           in the kernel.  This is helpful if you are debugging code that
 37           executes before the console is initialized.

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