Does your device tree have a /chosen node after u-boot is done with it?
find_legacy_serial_ports() can crash otherwise (we really should fix that).

latest u-boot does add the chosen node.<br>
As far as I know it's for initrd setup ... don't know if it's complete.<br>

On other PowerPC system I could see something like this during boot :
-> find_legacy_serial_port()
stdout is /soc8568@e0000000/serial@4600
legacy_serial_console = 1
default console speed = 115340
<- find_legacy_serial_port()
Should I see this message also ?

One thing that sticks out from the above is that you ask for ttyS0, but the
stdout you list from the other system corresponds to ttyS1. Is this just a
difference between the two systems?

Yes - the log from the MPC8568 is a copy&paste from another
posting. It's not my system.<br>
I want ttyS0.<br>
