[v4,0/3] hw/arm/virt_acpi_build: Generate DBG2 table

Message

Eric Auger Oct. 7, 2021, 7:29 a.m. UTC

This series generates the ACPI DBG2 table along with machvirt.

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.

History:

v3 ->v4:
- fix revision in header (0)
- added Michael's R-b
- address 2 minor style issues (Drew, Igor)

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()
