[PATCH 00/10] Extract bindings in dom0less code

[Alejandro Vallejo <alejandro.garciavallejo@xxxxxxx>]

Hi,

pipeline: 
https://gitlab.com/xen-project/people/agvallejo/xen/-/pipelines/1941315850

With boot_domain common between architectures, we're now in a position to use
it as the common ground to dump results of dom0less bindings. This series is
largely code motion with a few tweaks to make it simple for x86 to hook into
the dom0less bindings.

The idea is to create a parse_dom0less_node() function, that takes a boot_domain
and depending on the bindings found on the xen,domain node, populates it one way
or the other. parse_dom0less_node() calls internally an
arch_parse_dom0less_node() function to allow arch-specific bindings or checks.

Patch 9: "dom0less: Reinitialise all variables on each loop iteration" is a
         separate bugfix. Patch 10 does code motion and implicitly fixes it
         too, but I added it so it can be backported to stable branches.

Alejandro Vallejo (10):
  static-evtchn: Add missing include
  dt: Add cf_check to device-tree.c function pointers
  dom0less: Move asm-generic/dom0less-build.h -> xen/dom0less-build.h
  bootfdt: Add createdomain arguments to boot_domain
  dom0less: Introduce kernel_info into the domain creation loop
  dom0less: Create llc_color_str field in boot_domain
  dom0less: Turn arch_create_domUs into arch_parse_dom0less_node()
  dom0less: Allow arch_parse_dom0less_node() to be fallible
  dom0less: Reinitialise all variables on each loop iteration
  dom0less: Parse dom0less bindings into createdomain input args
