+After a discussion with NXP it is allowed to download the proprietary firmware (for the WLAN/BT module) from NXP and integrate it into the rootfs.
+Deployment via the armbian-firmware repo was rejected.
+Unfortunately, there seems to be no interest on the part of NXP to integrate the WLAN/BT firmware into linux-firware in a timely manner.
