Getting serial console output on new imx7d tqma7 board UART4

Wed Jul 29 12:52:04 EDT 2020
I have spent the last couple of days trying to port our bootloader
from u-boot to barebox 2020.07 but have yet to get any console output.
Our product is based on tqma7d i.MX7 dual core cpu and uses UART4 for
serial console and boots from internal eMMC.
I created a new board inspired from "NXP i.MX7 SabreSD board" and
tried to only add the basic in the first step to get a console output
working. The image is built using ptxdist and the imx_v7_defconfig
where the new board is selected. The image is flashed with "dd
if=barebox-image of=/dev/mmcblk0 bs=1024 skip=1 seek=1 conv=fsync".
The device works using u-boot 2020.07 with the same device trees but
we thought it was time to try out barebox since u-boot felt a little
bloated :)
So can anyone be of assistance and tell me what I'm missing?
