It has been on a slow burn since I became a new dad (shortly after the RFC).
I've gradually regained free time, and so I've been able to change that
slow burn to a moderate burn in the last couple weeks.

Most of my progress has been around build environment improvements.  I've done
some work stripping it down to the bare minimum required to build a new arch
and rooting the commit history from there, and some work with incorporating it
into the gitlab CI, containerizing the build and QEMU run, etc...

As far as hypervisor status:  I'm just about done with incorporating the boot
module FDT parsing code, extracting kernel info and ram regions
(taken/generalized from arch/arm), plus implementing the arch-specific pieces
of domain_create().

On the verge of being able to dive into a guest kernel and see what breaks
first :)

I'm expected to commit an extra day or two per week in the next month or so at
Vates, so this will considerably bump up my cadence in comparison to the last
few months.

That would be great :)
