[U-Boot] MPC8313ERDB board reset problem

[Deepak Gopalakrishnan]

Hi im using mpc8313erdb board. and i have modified the u-boot 1.3.0 code 
to suit my needs. But the problem is that now as soon as power up the 
board,  the initial msgs are dumped on the telnet...and then as soon as 
the prompt is displayed....it resets....and keeps on doing the same... 
the thing is i dont know what change has caused this....it would be of 
great help if anyone can guide me identify wat component have i messed 
up... 

thanks and regards in advance
