Currently I do not have an i.MX8QXP MEK board with RevB CPU and cannot
test, but I have an i.MX8QXP based custom SoM with console on ttyLP2.
Here I tested with NXP BSP kernel based on branch imx_4.14.98_2.0.0_ga
and it boots successfully (with NFS rootfs or rootfs on eMMC).

I cannot test NXP 4.19.35 kernel on this SoM yet, so not sure if it
would boot.
