- add grub2-emu-4-all.patch
  * Build 'grub2-emu' wherever possible, to allow a better
    implementation of that feature.
- add grub2-s390x-06-loadparm.patch,
- add grub2-commands-introduce-read_file-subcommand.patch:
  * allow s390x to telecontrol grub2.  (bsc#891946, bsc#892852)
- add grub2-s390x-06-loadparm.patch:
  * ignore case and fix transliteration of parameter.  (bsc#891946)

  * Ignore partition tables on s390x. (bsc#935127)
- add grub2-efi-chainload-harder.patch:
  * allow XEN to be chain-loaded despite firmware flaws.  (bnc#887793)
  * Do not use shim lock protocol for reading pe header, it won't be
  available when secure boot disabled (bsc#943380)
  * Make firmware flaw condition be more precisely detected and add
  debug message for the case
  * Check msdos header to find PE file header (bsc#954126)
- grub2-s390x-04-grub2-install.patch:

implementation of that feature.
- add grub2-s390x-06-loadparm.patch,
- add grub2-commands-introduce-read_file-subcommand.patch:
* allow s390x to telecontrol grub2. (bsc#891946, bsc#892852)
- add grub2-s390x-06-loadparm.patch:
* ignore case and fix transliteration of parameter. (bsc#891946)
- add grub2-s390x-07-add-image-param-for-zipl-setup.patch
* Add --image switch to force zipl update to specific kernel
(bsc#928131)

* Ignore partition tables on s390x. (bsc#935127)
- add grub2-efi-chainload-harder.patch:
* allow XEN to be chain-loaded despite firmware flaws. (bnc#887793)
* Do not use shim lock protocol for reading pe header, it won't be
available when secure boot disabled (bsc#943380)
* Make firmware flaw condition be more precisely detected and add
debug message for the case
* Check msdos header to find PE file header (bsc#954126)
- grub2-s390x-04-grub2-install.patch:
* streamline boot to grub menu. (bsc#898198)
* Force '/usr' to read-only before calling kexec. (bsc#932951)
- grub2-once:
* add '--enum' option to enumerate boot-entries in a way
actually understood by 'grub2'. (bsc#892852, bsc#892811)
