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: https://gitlab.com/xen-project/people/agvallejo/xen/-/pipelines/1758167851 v2: https://lore.kernel.org/xen-devel/20241226165740.29812-1-dpsm...@apertussolutions.com/ v1: https://lore.kernel.org/xen-devel/20241123182044.30687-1-dpsm...@apertussolutions.com/ 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. ========= Alejandro Vallejo (1): x86/hyperlaunch: Add helpers to locate multiboot modules Daniel P.
