This series generates the ACPI DBG2 table along with machvirt.
It applies on top of Igor's
[PATCH v4 00/35] acpi: refactor error prone build_header() and
packed structures usage in ACPI tables

The DBG2 specification can be found at
https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/acpi-debug-port-table.

DBG2 is mandated by ARM SBBR since its v1.0 release (the rationale
behind is Windows requires it on all systems).

The DBG2 is used to describe a debug port, used by the kernel debugger.

This series and its dependency can be found at
https://github.com/eauger/qemu.git
branch: igor_acpi_refactoring_v4_dbg2_v3

History:
v2 -> v3:
- addressed all comments from Igor on v2:
  patches 2/3 swapped
  style adjustments in "hw/arm/virt_acpi_build: Generate DBG2 table"
  + more precision on spec references

v1 -> v2:
- rebase on top of Igor's series and use acpi_init_table/acpi_table_composed
  and build_append_int_noprefix()


Eric Auger (3):
  tests/acpi: Add void table for virt/DBG2 bios-tables-test
  hw/arm/virt_acpi_build: Generate DBG2 table
  bios-tables-test: Generate reference table for virt/DBG2
