	  One well known example of this is PCMCIA- or PC-cards, credit-card

	  plugged into slots found on all modern laptop computers.  Another
	  example, used on modern desktops as well as laptops, is USB.

	  Enable HOTPLUG and KMOD, and build a modular kernel.  Get agent
	  software (at <http://linux-hotplug.sourceforge.net/>) and install it.
	  Then your kernel will automatically call out to a user mode "policy
	  agent" (/sbin/hotplug) to load modules and set up software needed
	  to use devices as you hotplug them.

config DEBUG_HWERR
	bool "Hardware error interrupt debugging"
	depends on DEBUG_KERNEL
	help
	  When enabled, the hardware error interrupt is never disabled, and
	  will happen immediately when an error condition occurs.  This comes
	  at a slight cost in code size, but is necessary if you are getting
	  hardware error interrupts and need to know where they are coming
	  from.

config DEBUG_ICACHE_CHECK
	bool "Check Instruction cache coherancy"
	depends on DEBUG_KERNEL
	depends on DEBUG_HWERR
	help
	  Say Y here if you are getting wierd unexplained errors. This will
	  ensure that icache is what SDRAM says it should be, by doing a
	  byte wise comparision between SDRAM and instruction cache. This
	  also relocates the irq_panic() function to L1 memory, (which is
	  un-cached).

config DEBUG_KERNEL_START
	bool "Debug Kernel Startup"
	depends on DEBUG_KERNEL
	help
	  Say Y here to put in an mini-execption handler before the kernel
	  replaces the bootloader exception handler. This will stop kernels
	  from dieing at startup with no visible error messages.

config DEBUG_SERIAL_EARLY_INIT
	bool "Initialize serial driver early"
	default n
	depends on SERIAL_BFIN
	help
	  Say Y here if you want to get kernel output early when kernel
	  crashes before the normal console initialization. If this option
	  is enable, console output will always go to the ttyBF0, no matter
	  what kernel boot paramters you set.

config DEBUG_HUNT_FOR_ZERO
	bool "Catch NULL pointer reads/writes"
	default y
	help
	  Say Y here to catch reads/writes to anywhere in the memory range
	  from 0x0000 - 0x0FFF (the first 4k) of memory.  This is useful in
	  catching common programming errors such as NULL pointer dereferences.

	  Misbehaving applications will be killed (generate a SEGV) while the
	  kernel will trigger a panic.

	  Enabling this option will take up an extra entry in CPLB table.
	  Otherwise, there is no extra overhead.

config DEBUG_BFIN_NO_KERN_HWTRACE
	bool "Trace user apps (turn off hwtrace in kernel)"
	default n
	help
	  Some pieces of the kernel contain a lot of flow changes which can
	  quickly fill up the hardware trace buffer.  When debugging crashes,
	  the hardware trace may indicate that the problem lies in kernel
	  space when in reality an application is buggy.

	  Say Y here to disable hardware tracing in some known "jumpy" pieces
	  of code so that the trace buffer will extend further back.

config DUAL_CORE_TEST_MODULE
	tristate "Dual Core Test Module"
	depends on (BF561)
	default n
	help
	  Say Y here to build-in dual core test module for dual core test.

config CPLB_INFO
	bool "Display the CPLB information"
	help
	  Display the CPLB information.

config ACCESS_CHECK
	bool "Check the user pointer address"
	default y
	help
	  Usually the pointer transfer from user space is checked to see if its
	  address is in the kernel space.

	  Say N here to disable that check to improve the performance.
