Thank you, that looks good.

This article, despite giving a rough guide on what is needed, is
unfortunately based on an old version of Genode and contains some
significant misconceptions. Most substantial for you: The Uboot version
it uses is tailored to 'tz_vmm' on the USB-Armory while the Linux
version is tailored to 'tz_vmm' on the i.MX53-QSB.

Even though Genode is still coming up, I suppose that Linux collides
with the unexpectedly altered hardware initialization. The version I'm
using says "U-Boot 2014.07-rc1-02695-g3ab9a12 (Jun 25 2014 - 13:17:24)".
However, I can't tell which sources we used for building it (we simply
google'd for it back then) but what is for sure is that we didn't
patched the sources for 'tz_vmm'.

Cheers,
Martin
