The 'len' bug only shows up if both of these conditions are met:

1) You're booting an OF-enabled kernel (i.e. there's an fdt)
2) The fdt is wrapped in a dtu image (type IH_TYPE_FLATDT)

I didn't test having the fdt merged in with other entities in a combined image. I just
made a dtu and told the bootm command to use it. So if you want to test this code, I
think just wrapping the three pieces individually should be sufficient.

Part of the problem is that the code looks for a dtu image. If you combine all three
chunks into one image, then I don't know what the code will do, because the image type
won't be IH_TYPE_FLATDT.
