I would strongly recommend upgrading the firmware in any case, because
of work I did (and submitted back through Jon @ SolidRun) to improve
the eye mask on the 10G Ethernet interfaces. I'm using the 18.12
version. Firmware build instructions can be found at:
https://developer.solid-run.com/knowledge-base/armada-8040-machiatobin-u-boot-and-atf/
I've booted 5.6 recently on a number of Armada 8040 based boards
without issue, likely all running the later firmware.
