Does imx8qm need changes in the dt bindings? Unless you are aware of reasons preventing us from enabling it on imx8qm, then we could go for imx8qm as well (reusing imx8qxp- compatible).

Pure memory-to-memory are typically not enabled per-board, but just per-platform. So you can drop the disabled status here. Thanks, Ezequiel
