69 string "Kernel command line"
70 default "root=/dev/mtdblock3"
72 Pass additional commands to the kernel.
75 bool "Enable ETRAX watchdog"
77 Enable the built-in watchdog timer support on ETRAX based embedded
80 config ETRAX_WATCHDOG_NICE_DOGGY
81 bool "Disable watchdog during Oops printouts"
82 depends on ETRAX_WATCHDOG
84 By enabling this you make sure that the watchdog does not bite while
85 printing oopses. Recommended for development systems but not for
88 config ETRAX_FAST_TIMER
89 bool "Enable ETRAX fast timer API"
91 This options enables the API to a fast timer implementation using
92 timer1 to get sub jiffie resolution timers (primarily one-shot
94 This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.
97 bool "Preemptible Kernel"
99 This option reduces the latency of the kernel when reacting to
100 real-time or interactive events by allowing a low priority process to
101 be preempted even if it is in kernel mode executing a system call.
102 This allows applications to run more reliably even when the system is
105 Say Y here if you are building a kernel for a desktop, embedded
106 or real-time system. Say N if you are unsure.
