Hi Aruna,

This is a FAQ.
   <http://www.denx.de/wiki/view/DULG/UBootCrashAfterRelocation>

Just because your SDRAM configuration passes the ddr test doesn't 
necessarily mean it is working 100% correctly.  Misconfigured SDRAM will 
"work" if it isn't driven hard (i.e. pipelining effectively not being used).

If your SDRAM *is* working as you claim, you found a new problem and 
will have to update the FAQ.  :-/

HTH,
