Hi,
I've fixed a couple of issues with the 2 refactors.
1. The proposed fixup by Daniel went ahead and was lost on rebase. v7 includes
it back.
2. The pre-requisite rename of bootfdt.c to bootinfo-fdt.c was mis-squashed on
rebase too. This, too, has been restored to keep a tidier history.
Otherwise, same old.

Original cover letter
=====================
This is the aftermath of this discussion:
https://lore.kernel.org/xen-devel/DA1WWRUQLCAG.ZTVR1HXJ85V0@amd.com/https://lore.kernel.org/xen-devel/DA1WWRUQLCAG.ZTVR1HXJ85V0@amd.com/
It's a first round of cleanup and preparation to have a much easier time
later when integrating dom0less boot into hyperlaunch.
The refactor on device-tree/ is _fine_ by I'm open to other suggestions
to achieve the same thing. In particular, after this series x86 can
unflatten the DT host device tree when it has CONFIG_DOM0LESS_BOOT set,
which enables the builder to use factored-out functions from
dom0less-build.c (not done here).
The diffstat is deceptive because I renamed a large file and then
created a new file with the same name. There aren't that many LoC
changes.
Alejandro Vallejo (11):
x86: Replace arch-specific boot_module with common one
xen: Refactor kernel_info to have a header like boot_domain
x86: Replace arch-specific boot_domain with the common one
xen/dt: Move bootfdt functions to xen/bootfdt.h
xen/dt: Move bootinfo functions to a new bootinfo.h
xen/dt: Rename bootfdt.c -> bootinfo-fdt.c
xen/dt: Extract bootinfo-independent functions to bootfdt.c
xen/dt: Extract helper to map nodes to module kinds
xen: Split HAS_DEVICE_TREE in two
xen/dt: ifdef out DEV_DT-related bits from device_tree.{c,h}
xen/dt: Allow CONFIG_DEVICE_TREE_PARSE to include device-tree/
