During custom board design in case bit swapping is required, bit swaps within a data byte, and swapping of byte 0/1 are allowed with some restrictions. The DM and DQS bits must not be swapped with any other signals. Bit swapping of the address or control bits is not allowed.
For more information, refer the Bit Swapping section in the DDR4 Board Design and Layout Guidance chapter of the AM62x DDR Board Design and Layout Guidelines.
It is recommended to update the schematics with the bit swapping changes for future reference or reuse.
