config ETRAX_CMDLINE
	string "Kernel command line"
	default "root=/dev/mtdblock3"
	help
	  Pass additional commands to the kernel.

config ETRAX_WATCHDOG
	bool "Enable ETRAX watchdog"
	help
	  Enable the built-in watchdog timer support on ETRAX based embedded
	  network computers.

config ETRAX_WATCHDOG_NICE_DOGGY
	bool "Disable watchdog during Oops printouts"
	depends on ETRAX_WATCHDOG
	help
	  By enabling this you make sure that the watchdog does not bite while
	  printing oopses. Recommended for development systems but not for
	  production releases.

config ETRAX_FAST_TIMER
       bool "Enable ETRAX fast timer API"
       help
         This options enables the API to a fast timer implementation using
	 timer1 to get sub jiffie resolution timers (primarily one-shot
	 timers).
	 This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.

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.
