[PATCH v3 00/16] Hyperlaunch device tree for dom0

[Alejandro Vallejo <agarciav@xxxxxxx>]

Hi,

This is an updated version of the hyperlaunch DTB series, with pending
feedback addressed. Some parts (notably the way modules are located) has
changed a little and is more generic with less duplication.

I've purposefully not added my S-by on anything I haven't touched
(besides rebasing) as most of the feedback had already been addressed by
Jason by the time I looked at it and it would be utterly nonsensical to
give myself authorship over it.

I'll be looking after the series moving forward.

v3 pipeline:

Cheers,
Alejandro

========= Original cover letter:

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.
