Hi,

This version contains a change in patch 2, where riscv_cpu_cfg() now
returns a const pointer to the RISCVCPUConfig struct instead of the
struct itself.

Minor changes were made in the remaining patches due to that.


Changes from v5:
- patches without review/acks: patch 2
- patch 2:
  - riscv_cpu_cfg() now returns a const pointer to RISCVCPUConfig
- v5 link: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg04906.html
