As mentioned in the i.MX6ULL Reference Manual, we have swapped the DDR Data lines.

But we would like to know if there are any configuration change in Software.

The Note in the i.MX6ULL Reference Manual refers as below,
when byte lane swapping was done target DDR IC register read value must be transposed according data line swapping.

Please let us know on how to configure the DDR IC Register read value according to our swapped values.
