[PATCH 00/15] Hyperlaunch device tree for dom0

["Daniel P. Smith" <dpsmith@xxxxxxxxxxxxxxxxxxxx>]

The Hyperlaunch device tree for dom0 series is the second split out for the
introduction of the Hyperlaunch domain builder logic. These changes focus on
introducing the ability to express a domain configuration that is then used to
populate the struct boot_domain structure for dom0. This ability to express a
domain configuration provides the next step towards a general domain builder.

The splitting of Hyperlaunch into a set of series are twofold, to reduce the
effort in reviewing a much larger series, and to reduce the effort in handling
the knock-on effects to the construction logic from requested review changes.

Much thanks to AMD for supporting this work.
