Fast Model all the way -- the processor used on the iMX53 platform does
not support hardware virtualisation.

It's ok for booting the h/v and kernel with a small userspace. I
wouldn't want to use it e.g. for self-hosting compilation or anything
like that.

We are using the example projects shipped with FastModels. I have just
created a wiki page which runs through the procedure for building one of
those. Please see:

It means that this processor does not support Hyp mode (which is
expected).
