I just tested v2022.07-rc6 and noticed that by reducing the value the
kontron pitx-imx8m (imx8mq) board does not start anymore. I locally
increased the value to 0xc000 and the board works again.

So should I increase the value just for this board or should I
increase the default value for the IMX8MQ?
