Now I'm in the process of adapting this patch to the new u-boot. Up to now I can compile a u-boot.bin and download it to the board. But after starting up the new u-boot I just see this on the serial port

So something went wrong in nand_init()? Two things you should do: a) as Wolfgung suggested previously: disable the Watchdog
Hmm OK I disabled the watchdog and enabled debugging and now this is what I get at the first boot after flashing:

The red LED is on and I can't input anything.
Starting with the second boot I get stuff like that ...
