experimental edk2 builds
------------------------

OVMF.stateless.fd
OVMF.stateless.secboot.fd
OVMF.stateless.secboot.pcr

  Stateless (== no persistent uefi variables) ovmf build.  Has secure
  boot support, the 'secboot' variant has secure boot enabled.  Does
  not require SMM support.

OVMF_CODE.4m.secboot.strictnx.fd

  OVMF build with strict NX configuration (using r-x for code, rw- for
  data).  Known to not work with some grub and linux kernel versions
  because they use the wrong memory type for allocations and run into
  NX faults.  Useful for bootloader development and CI.

QEMU_EFI.strictnx.fd
QEMU_EFI-strictnx-pflash.raw

  ArmVirt build with strict NX configuration (see above for details).

QEMU_EFI.secboot.testonly.fd
QEMU_EFI-secboot-testonly-pflash.raw
vars-template-secboot-testonly-pflash.raw

  ArmVirt build with secure boot support.

  Exposes the secure boot APIs, so they can be used for development /
  testing / CI.

  The EFI variable store is NOT protected, therefore the build is NOT
  suitable for production use.
