Hi All,
		I am porting Linux on MPC8266 custom board, after
getting in to Linux the system seems to be struck at a point.
Saved Environment variable:-
      bootargs console=ttyS0,11520 root=1f00 and downloaded the Kernel
image at address 0x02000000 in the RAM.
>From the u-boot prompt the bootm command is invoked as:- 
	bootm 0x02000000

After that what I get on the terminal is pasted below for your
I couldn't make out any thing from the output, can any body tell me
where I am doing wrong, and also I don't have any idea about the
bootargs argument "root". Can any body give the precise description of
this argument?

=> bootm 02000000 ## Booting image at 02000000...
