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