please, follow Martin's advice and do not use the outdated RUN_OPT
setting when using u-boot. If you replace it like this:

  RUN_OPT += --include image/uboot

You will even find a uImage in your 'var/run/tz_vmm_mx6' folder. Sorry I
was not recognizing that you were using the old, invalid setting for
RUN_OPT when writing my last mail.

I would suggest to build the u-boot uImage automatically via our build
system instead of fiddling around with elf or binary images manually.
