This adds ASL code as well as scripts for processing it, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Will be used for runtime acpi table generation. Note: This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them. Affected SeaBIOS files (GPLv2+ license headers added) <http://thread.gmane.org/gmane.comp.bios.coreboot.seabios/5949>: src/acpi-dsdt-cpu-hotplug.dsl src/acpi-dsdt-dbug.dsl src/acpi-dsdt-hpet.dsl src/acpi-dsdt-isa.dsl src/acpi-dsdt-pci-crs.dsl src/acpi.c src/acpi.h src/ssdt-misc.dsl src/ssdt-pcihp.dsl src/ssdt-proc.dsl tools/acpi_extract.py tools/acpi_extract_preprocess.py Each one of the listed people agreed to the following: > If you allow the use of your contribution in QEMU under the > terms of GPLv2 or later as proposed by this patch, > please respond to this mail including the line: > > Acked-by: Name <email address> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Jan Kiszka <jan.kiszka@siemens.com> Acked-by: Jason Baron <jbaron@akamai.com> Acked-by: David Woodhouse <David.Woodhouse@intel.com> Acked-by: Gleb Natapov <gleb@redhat.com> Acked-by: Marcelo Tosatti <mtosatti@redhat.com> Acked-by: Dave Frodin <dave.frodin@se-eng.com> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Acked-by: Kevin O'Connor <kevin@koconnor.net> Acked-by: Laszlo Ersek <lersek@redhat.com> Acked-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Acked-by: Isaku Yamahata <yamahata@valinux.co.jp> Acked-by: Magnus Christensson <magnus.christensson@intel.com> Acked-by: Hu Tao <hutao@cn.fujitsu.com> Acked-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Hu Tao <hutao@cn.fujitsu.com> Reviewed-by: Gerd Hoffmann <kraxel@redhat.com> Tested-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Tested-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Michael S.
