Juno is actually working out as a good reference platform. It works and
there aren't horrible things that need to be done to get the system into
a working state. AMD Seattle is a second system that will boot with
Hanjun's ACPI series with a couple of device driver patches (the SBSA
driver which is common with Juno and an Ethernet driver IIRC).
