[U-Boot] help command not working in u-boot

[Rupesh Kumar]

Hi

I have added a new command in the "test_cmd" u-boot. after adding test_cmd 
, help command  and many of the other commands are not working. help 
command gives 
Unknown command 'help' - try 'help'.
tftp gives 
Unknown command 'tftp' - try 'help'.
The command i have added is working fine.
I have seen the u-boot.map file, in this file all the commands are 
defined.
Can you please tell me what may be wrong.


Thanks
Rupesh
