config ETRAX_KGDB
bool "Use kernel gdb debugger"
---help---
The CRIS version of gdb can be used to remotely debug a running
Linux kernel via the serial debug port. Provided you have gdb-cris
installed, run gdb-cris vmlinux, then type
(gdb) set remotebaud 115200 <- kgdb uses 115200 as default
(gdb) target remote /dev/ttyS0 <- maybe you use another port
This should connect you to your booted kernel (or boot it now if you
didn't before). The kernel halts when it boots, waiting for gdb if
this option is turned on!
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.

Width in bytes of the Flash bus (1, 2 or 4). Is usually 2.
config ETRAX_ROOT_DEVICE
string "Root device name"
default "/dev/mtdblock3"
help
Specifies the device that should be mounted as root file system
when booting from flash. The axisflashmap driver adds an additional
mtd partition for the appended root file system image, so this option
should normally be the mtdblock device for the partition after the
last partition in the partition table.
