We are able to build ROM u-boot for MPC8260 based customs board.  We have 
observed a strange behavior of the board. When we power it up at the 
beginning of the day; it resets and resets. After a couple of power on/off 
we get the boot prompt.  I am giving the log what we get after we power it 
up for the first time.  Any help will be appreciated.
