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.
As far as I know it's for initrd setup ... don't know if it's complete.
Since we're using a dtb I omit the "console=..." argument for the
kernel. Is this correct ?
It's OK if you have /chosen/linux,stdout-path.
that sounds promising ! Haven't seen this and will have a closer look.
If "console=/dev/ttyS0,115200N8" argument is given the serial console
stops working after console_init....
On other PowerPC system I could see something like this during boot :
-> find_legacy_serial_port()
stdout is /[EMAIL PROTECTED]/[EMAIL PROTECTED]
legacy_serial_console = 1
default console speed = 115340
<- find_legacy_serial_port()
Should I see this message also ?
Only if you enable debug messages in legacy_serial.c.
ok.
Have I misconfigured anything ?
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.
I want ttyS0.

I appreciate your help !
