[PATCH v2 0/9] acpi: add ACPI support on QEMU ARM and RISC-V

[Heinrich Schuchardt]

QEMU 8.1.2 can create ACPI tables for the ARM and RISC-V architectures
Allow passing them through to the operating system.
Provide a new config fragment that enables this.

v2:
	consider ARM architecture too
	invoke write_acpi_tables() via EVT_LAST_STAGE_INIT

Heinrich Schuchardt (9):
  acpi: Kconfig symbol CONFIG_QFW_ACPI
  acpi: carve out qfw_acpi.c
  arrm: add ACPI fields to global data
  risc-v: add ACPI fields to global data
  acpi: enable writing ACPI tables on QEMU
  risc-v: add support for QEMU firmware tables
  riscv: allow usage of ACPI
  configs: qemu: add config fragment for ACPI
  arm: enable support for QEMU firmware tables
