introduce UEFI specific counterpart to acpi_find_rsdp_address() that will help to find RSDP address when [OA]VMF is used as firmware. It requires guest firmware or other guest app to place 1Mb aligned UefiTestSupport structure (defined in this patch) in RAM with UefiTestSupport::signature_guid set to AB87A6B1-2034-BDA0-71BD-375007757785 For test app details see commit (09a274d82f tests: introduce "uefi-test-tools" with the BiosTablesTest UEFI app) Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Wei Yang <richardw.yang@linux.intel.com> Message-Id: <1556808723-226478-9-git-send-email-imammedo@redhat.com> Reviewed-by: Michael S.
