This patch set is example of the sort of driver changes needed to boot
Juno using ACPI tables, which using the ACPI tables devloped for MS
Windows and published by ARM [1].

What about platform support?

I think Juno is just serving as an example here since it's from ARM and
thus various people have access to it already, etc. It's not the best
example of a server platform out there, since that wasn't its original
design purpose (but it's a wonderful platform nonetheless). There is
work currently in flight to offer other reference ACPI examples.

Ok, I see. This is a bit disappointing because it's actually the third
attempt to come up with a reference platform (after Exynos and X-Gene),
and it always seems to come down to deciding that this particular
platform doesn't really work with ACPI beyond basic booting.

Which platform(s) are you talking about? Are you sure it will be better
suited than the first three?

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).
