here is the output of bootm -v <image> (fixed version):
barebox:/ bootm -v /mnt/emmc0/boot/uImage
   Image Name:   Linux-3.10.14.vd2
   Created:      2015-08-06  10:13:02 UTC
   OS:           Linux
   Architecture: ARM
   Type:         Kernel Image
   Compression:  uncompressed
   Data Size:    2929528 Bytes = 2.8 MiB
   Load Address: 10008000
   Entry Point:  10008000

Loading U-Boot uImage '/mnt/emmc0/boot/uImage'
OS image not yet relocated
Passing control to ARM Linux uImage handler
no initrd load address, defaulting to 0x18000000
commandline: console=ttymxc2,115200n8

Starting kernel at 0x10008000, oftree at 0x18000000...

According to System.map bss ends at offset 0x0567b04. So bss will
overwrite the device-tree blob, because currently the oftree is placed
at 0x103d4000. I've played with the oftree-offset a little bit, and I
need at least 6MB offset from the end of the kernel image in order to
get the system booting.
