[PATCH 00/10] v3: Boot modules for Hyperlaunch

[Christopher Clark <christopher.w.clark@xxxxxxxxx>]

This is a v3 series of work for Hyperlaunch for the Xen hypervisor,
an update to v2 and implementing a subset of the v1 series and functionality,
with changes made to address the community feedback provided on the patches.
Changes since the earlier versions of the series are described below.

The patches in this series are primarily derived from patches 2-4 of the
v1 full series, in a series of smaller patches for ease of review.

Thanks to AMD for supporting this work.

Changes since v2:
- combined v2 patches 7 and 8 for common review
- rebased the v2 series onto the current tip of staging (sorry)
- fixed the placement of the patch changelogs
- provided the changes description in the cover letter

Changes since v1:
- the v2 and v3 series implement functionality from v1 patches 2-4
    - v2 series objective is to enable efficient patch review in support
      of merging the functionality into the hypervisor. It implements a
      subset of the v1 series, incorporating changes from community
      feedback.
- the bootstrap map is made accessible early in the v2 series via both
  multiboot and boot module arguments until later in the series where
  multiboot use is retired. This allows for incremental conversion across
  several patches from multiboot to boot modules.
- the 32-bit x86 boot environment header is removed, and changes are
  made to allow the new common bootinfo headers to be used instead.
- Arm and RISC-V architecture bootinfo headers are added to ensure that
  builds on those architectures can complete correctly.
- The KConfig patch to set the maximum number of boot modules allowed
  is not included in this series, replaced with a static maximum define.

Christopher Clark (10):
  x86 setup: move x86 boot module counting into a new boot_info struct
  x86 setup: per-arch bootmodule structure, headroom field
  x86 setup: change bootstrap map to accept new boot module structures
  x86 setup: porting dom0 construction logic to boot module structures
  xsm: switch XSM init to boot info structures
  x86 setup, microcode: switch to the new bootinfo structures
  x86 boot: define paddr_t and add macros for typedefing struct pointers
  x86, arm, riscv: add per-arch bootinfo headers
  arm setup: use common integer-typed bootmod definition
  x86 setup: refactor efi, pvh and multiboot entrypoints to new boot
