[U-Boot] booting os 'Unknown OS' (1) is not supported

One needs parameters for that, but the information looks ok:

[...]

>> [fedya at discordy linux-linaro-tracking]$ mkimage -l arch/arm/boot/uImage
>> Image Name:   Linux-3.13.0-rc8
>> Created:      Fri Jan 17 15:47:36 2014
>>
>> Image Type:   ARM Linux Kernel Image (uncompressed)
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If you check common/image.c:261 (image_print_type), you'll see that this
is correctly decoded from the image, so the image seems perfectly fine.
It just makes no sense that U-Boot then complains about an unknown OS.
This means that between the time the header is printed and between the
time the code wants to boot it, the memory does not contain what it
should anymore.

Cheers
