grub2/grub2-secureboot-install-signed-grub.patch
Michael Chang 62e3547e57 Accepting request 741033 from home:michael-chang:devel 
- Version bump to 2.04
  * removed
    - translations-20170427.tar.xz
  * grub2.spec
    - Make signed grub-tpm.efi specific to x86_64-efi build, the platform
      currently shipped with tpm module from upstream codebase
    - Add shim_lock to signed grub.efi in x86_64-efi build
    - x86_64: linuxefi now depends on linux, both will verify kernel via
      shim_lock
    - Remove translation tarball and po file hacks as it's been included in
      upstream tarball

Subject: [PATCH] grub-install: handle signed grub installation on arm64-efi
Use grub2-install to handle signed grub installation for arm64 UEFI secure
boot, the default behavior is auto, which will install signed grub whenever
detected.
Two options, --suse-force-signed and --suse-inhibit-signed, can be used to
override the default auto detecting behavior. The former will force to use
prebuilt signed image and thus will fail if missing, the latter will always use
'mkimage' to create unsigned core image per the user's running environment.
