[U-Boot-Users] do_bootm_linux problem

[yan weichuan]

I think you have to make sure that you serial port is working well for your 
kernel.
pls check the command line in your linux config. Pay attention to choose 
the ttyS0 or ttyS1 for your board, and set the baurdrate  right both in the 
command line and the terminal.
