config PREEMPT
	bool "Preemptible Kernel"
	help
	  This option reduces the latency of the kernel when reacting to
	  real-time or interactive events by allowing a low priority process to
	  be preempted even if it is in kernel mode executing a system call.
	  This allows applications to run more reliably even when the system is
	  under load.

	  Say Y here if you are building a kernel for a desktop, embedded
	  or real-time system.  Say N if you are unsure.

config MN10300_CURRENT_IN_E2
	bool "Hold current task address in E2 register"
	default y
	help
	  This option removes the E2/R2 register from the set available to gcc
	  for normal use and instead uses it to store the address of the
	  current process's task_struct whilst in the kernel.

	  This means the kernel doesn't need to calculate the address each time
	  "current" is used (take SP, AND with mask and dereference pointer
	  just to get the address), and instead can just use E2+offset
	  addressing each time.

	  This has no effect on userspace.

config MN10300_USING_JTAG
	bool "Using JTAG to debug kernel"
	default y
	help
	  This options indicates that JTAG will be used to debug the kernel. It
	  suppresses the use of certain hardware debugging features, such as
	  single-stepping, which are taken over completely by the JTAG unit.

config MN10300_RTC
	bool "Using MN10300 RTC"
	depends on MN10300_PROC_MN103E010
	default n
	help

	  This option enables support for the RTC, thus enabling time to be
	  tracked, even when system is powered down. This is available on-chip
	  on the MN103E010.

config MN10300_WD_TIMER
	bool "Using MN10300 watchdog timer"
	default y
	help
	  This options indicates that the watchdog timer will be used.

config PCI
	bool "Use PCI"
	depends on MN10300_UNIT_ASB2305
	default y
	help
	  Some systems (such as the ASB2305) have PCI onboard. If you have one
	  of these boards and you wish to use the PCI facilities, say Y here.

	  The PCI-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>, contains valuable
	  information about which PCI hardware does work under Linux and which
	  doesn't.
