It is booting all right it seems.

Today it looks like Hillf Danton found the problem: if I understand correctly
the code is executing arm32-on-arm64 (virtualized QEMU for ARM32
on ARM64?) and that was not working with the vexpress QEMU model
because not properly tested.

I don't know if I understand the problem right though :/
