Things mostly work.  The remaining issues are:

* The EC2 API "shutdown" / "reboot" message is sent via a pl061 GPIO device
and we're dropping it on the floor; consequently "reboot" does nothing at
all, while "shutdown" does nothing until EC2 times out and does a hard
poweroff (without filesystems being unmounted etc).

* Device hotplug doesn't work (ACPI issues?) so you need to manually rescan
after attaching new disks.

* FreeBSD doesn't boot on "bare metal" Graviton instances, due to missing
some drivers.  (NetBSD works though -- anyone want to port their code?)

Oh, and a generic ARM issue: It's not a Tier 1 platform yet, so freebsd-update
doesn't work and packages aren't always as up-to-date as on x86.  But I think
those are being worked on...
