LS1043 DDR Bit Swap Workaround

Greetings,

We are working on a custom board with LS1043 and the prototype ended up not respecting the nibble boundary bit swapping rules. Lots of questions here mentioning this topic, like this one https://community.nxp.com/t5/Layerscape/LS1043-ddr4-bit-swap-in-nibble-only/m-p/987745.

Is there a workaround for this? Can I manually enter training parameters into the controller? Any help is appreciated!
