[Qemu-devel] [PATCH v3 08/13] tests: acpi: add a way to start tests with UEFI firmware

[Igor Mammedov <imammedo@redhat.com>]

For testcase to use UEFI firmware, one needs to provide and specify
firmwarei and varstore blobs names in test_data { uefi_fl1, uefi_fl2) }
fields respectively and RAM start address plus size where to look for
test structure signature. Additionally testcase should specify
bootable cdrom image uefi-boot-images EFI test utility.

v3:
  * drop data_dir prefix and firmware will come from pc-bios directly
  * add cdrom option so test could use it for providing boot cdrom image
  * add TODO comment convert '-drive if=pflash' to new syntax (Laszlo)
v2:
  * move RAM start address and size to test_data, as it could differ
    between boards (and even versions)
