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.
