NXP Layerscape

After reprograming the barebox image and change the DIP switch to boot from flash 1 instead of using the U-Boot  CPLD command, I got some garbage output on the serial. This is what you mention below.

Some hope.

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:

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.
