it's not u-boot but it's parameters.

here is how to fix it (i did't write this, just copy/paste). i just
tested it with success:

- bring up the boot menu of NAND u-boot
- switch the console to USB
- enter the u-boot command line with

  neocon /dev/ttyACM{0,1,2}

  (or use the serial communication program of your choice)

- enter the following two commands:

  setenv bootcmd setenv bootargs \${bootargs_base} \${mtdparts}\; nand
  read.e 0x32000000 kernel 0x300000\; bootm 0x32000000

- you can now boot with


The change is persistent, so you'll be able to boot large kernels
from now on. A small drawback of this change is that loading the
kernel now takes a little bit longer.
