[Qemu-devel] [PATCH v3 1/5] roms: add the edk2 project as a git submodule

[Laszlo Ersek <lersek@redhat.com>]

The roms/edk2 submodule can help with three goals:
- build the OVMF and ArmVirtQemu virtual UEFI firmware platforms (to be
  implemented later),
- build the EfiRom tool on the fly, which is used in roms/Makefile, for
  building the "efirom" target,
- build UEFI test applications (to be run in guests), for qtest support.

Edk2 commit 85588389222a3636baf0f9ed8227f2434af4c3f9 stands for the latest
"stable tag", namely "edk2-stable201811".

The edk2 repository tracks some binary files that should not be removed by
QEMU's top-level "make clean"; exempt the full pathnames from the "find"
command.
