It doesn't reboot cleanly with a USB serial adapter attached!
Jfyi, gave me a scare first time, when I thought I broke something ^^.

Can't comment on that. Sascha did the integration.

Can comment on that: Last time I did this, I wrote some documentation:
https://www.barebox.org/doc/latest/boards/layerscape.html

There I flashed barebox from another barebox booted from SD-Card.
I'd assume that should still work. I can't recall how the CPLD
needed to be tickled, but it would be helpful to know whether doing
it like described in the documentation doesn't work for you.

Cheers,
Ahmad
