Message

The patch series introduces the following:
- provide a minimal amount of changes to add initial RISC-V support
  to make Xen binary buildable and runnable for RISC-V architecture
  which can be used for future development and testing.
- add RISC-V 64 cross-compile build jobs to check if any new changes
  break RISC-V build.

Changes in V4:
- Rebase on mainline 'staging'.
- Code style fixes and commit message updates.
- Minor changes of riscv/Makefile and build.yaml

Changes in V3:
- Remove include of <asm/config.h> from head.S.

Changes in V2:
- Remove the patch "automation: add cross-compiler support
  for the build script" because it was reworked as a part of the patch
  series "CI: Fixes/cleanup in preparation for RISCV".
- Remove the patch "automation: add python3 package for riscv64.dockerfile"
  because it is not necessary for RISCV Xen binary build now.
- Rework the patch "arch/riscv: initial RISC-V support to build/run
  minimal Xen" according to the comments about v1 of the patch series.
- Add HYPERVISOR_ONLY to RISCV jobs in build.yaml after rebasing on
  "CI: Fixes/cleanup in preparation for RISCV" patch series.
