imx6s: Can determine if DDR data lines are swapped via linux config

I have a commercial reference board (Hummingboard Gate) that the schematic excludes the DDR connections to the imx6.    We are about to make a custom board but we wanted to minimize the software changes.   


1)  What register names control the Data line swapping (Looked in the RM and don't see it in the MMDC or IOMUX )

2)  Is there a way to query the registers via linux to deteremine what our current setup is?
