Hi,
We found some threads regarding DDR data bits swapping like below.
https://e2e.ti.com/support/processors/f/791/p/836370/3093164#3093164
These mentioned that nothing is needed to be considered about the software design for DDR data bit swapping. Do you have any document describing the mechanism how processor can recognize bit swapping ?

Hi,
There isn't any mechanism. The explanation is that the processor always writes and reads the same bit on the DDR interface. It doesn't matter if this is the same bit on the DDR side.
