the stdout-path property of the chosen node is still broken in this verion.
if :
stdout-path = "serial0:115200n8";
is set in the DTS, the console output should go on serial0 (aka dbgu)
cf Documentation/devicetree/bindings/chosen.txt

With this patch applied, this is not the case anymore.
Adding console=ttyS0,115200 in the chosen node is not the solution here.


regards,
Richard.
