Sounds like this trick didn't work ([1]) and we also lost xen log for 
the other the flights (see xen-unstable-smoke [2]) thought they are 
still passing.
Looking at the device-tree again, I thought the serial aliases were 
existing in 3.16.7-ctk one but it seems that I looked at the wrong DT. 
Sorry for that.
This means that the path to the serial is different between 3.16 and 
4.10 and we have no common one. For now, I would revert it.
A per-flight override sounds quite ugly, so I am not sure how to solve 
this in the future. Any opinions?
Regardless that I gave the wrong alias on the previous e-mail for 4.10. 
Below the list of serial alias:
                serial0 = "/soc/serial@12C00000";
                serial1 = "/soc/serial@12C10000";
                serial2 = "/soc/serial@12C20000";
                serial3 = "/soc/serial@12C30000";
So for the alias should be serial2.
