Ah, well here lies the issue. As per hpa subarch was not designed for defining
a hypervisor, but rather at least subarch PC (0) [should be used if the

need a special boot flow". Does that follow the definition of HVMlite?

Yes. HVMlite is going to use baremetal boot flow.

OK great. That still means the code will run, and if we can avoid that
why not. I am fine with annotating this as future work to help. Let me
then ask as well, how about the rest of the code during and after
startup_32() and startup_64() -- are we sure that's all safe ?

I can't be sure, all I can say is that so far I haven't seen any problems.
