AM4378: DDR3L Byte Swapping possible?

Team,

I couldn't any confirmation if byte swapping on the DDR3L interface is possible or not. 

In my case the complete bytes incl DQM and DQS should be swapped:

DQ[0-7] + DQM0 + DQS0+/-  swapped with DQ[8-15] + DQM1 + DQS1+/-

Is this allowed on AM437x?

Thanks,
  Robert
