Hi Mr Denk,
Please define "crash". Does the board simply reset (like after a watchdog timeout), or is there any error message, or what?
The board simply resets.
You always have to configure both sides to match, i. e. if you enable the watchdog in U-Boot you must do so in Linux, and if you don;t enable it in U-Boot you must not enable it in Linux (althought in that case you will not crash the system).
How do I enable it in Linux?

Most probably Linux is not crashing but just reset by the watchdog.
Do I have to enable watchdog support in u-boot for the mpc_8xx driver to
run?

If so what can I about the Linux crashes?
