The Zyxel NAS540 seems to have a Freescale QorIQ LS1024A SoC. There is
no mainline barebox support for this SoC, so Zyxel must have created
their own patches. I know nothing about these patches nor about the SoC,
so I'm sorry I can't really help you.
What I can say is that normally barebox outputs stuff out of the console
even without valid environment or kernel. That is configurable though,
so I can't tell for sure.
