Rather than a new stub-bootloader we should switch over to using the
same boot-wrapper.git as Linaro and KVM are using[0], and perhaps
enhancing it to meet our needs.

One benefit of that is that when they come to do stuff on real hardware
we will already be somewhat aligned with something which looks a bit
like a bootloader so it should be easier for us to transition too.

It also has other benefits like enabling us to use semi-hosting to pull
the files off the host filesystem.
