	  bus system, i.e. the way the CPU talks to the other stuff inside

	  your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or

	  Unicore processors can not fetch/store information which is not

	  address divisible by 4. On 32-bit Unicore processors, these non-aligned

	  fetch/store instructions will be emulated in software if you say

	  here, which has a severe performance impact. This is necessary for

	  correct operation of some network protocols. With an IP-only

	  configuration it is safe to say N, otherwise say Y.

	  command-line options your boot loader passes to the kernel.

config STRICT_DEVMEM

	bool "Filter access to /dev/mem"

	depends on MMU

	---help---

	  If this option is disabled, you allow userspace (root) access to all

	  of memory, including kernel and userspace memory. Accidental

	  access to this is obviously disastrous, but specific access can

	  be used by people debugging the kernel.



	  If this option is switched on, the /dev/mem file only allows

	  userspace access to memory mapped peripherals.



          If in doubt, say Y.



config EARLY_PRINTK

	def_bool DEBUG_OCD

	help

	  Write kernel log output directly into the ocd or to a serial port.



	  This is useful for kernel debugging when your machine crashes very

	  early before the console code is initialized. For normal operation

	  it is not recommended because it looks ugly and doesn't cooperate

	  with klogd/syslogd or the X server. You should normally N here,

	  unless you want to debug such a crash.



config DEBUG_STACK_USAGE

	bool "Enable stack utilization instrumentation"

	depends on DEBUG_KERNEL

	help

	  Enables the display of the minimum amount of free stack which each

	  task has ever had available in the sysrq-T output.



# These options are only for real kernel hackers who want to get their hands dirty.

config DEBUG_LL

	bool "Kernel low-level debugging functions"

	depends on DEBUG_KERNEL

	help

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

	  in the kernel.  This is helpful if you are debugging code that

	  executes before the console is initialized.



config DEBUG_OCD

	bool "Kernel low-level debugging via On-Chip-Debugger"

	depends on DEBUG_LL

	default y

	help

	  Say Y here if you want the debug print routines to direct their

	  output to the UniCore On-Chip-Debugger channel using CP #1.

	depends on DEBUG_OCD



config DEBUG_UART

	default "0"

	help

	  Choice for UART for kernel low-level using PKUnity UARTS,

	  should be between zero and one. The port must have been

	  initialised by the boot-loader before use.
