- Added the following patches for bsc#1166850
  zipl: fix secure boot config handling:
  * s390-tools-sles15sp2-01-zipl-Add-missing-options-to-help-output.patch
  * s390-tools-sles15sp2-02-zipl-allow-stand-alone-secure-option-on-command-l.patch

  * s390-tools-sles15sp2-04-zipl-fix-zipl.conf-man-page-example-for-secure-boot.patch
- Modified the spec file so that the kernel used for the SCSI dump
  tool is named zfcpdump-image instead of zfcpdump_part.image. This
  is to match the new version of zipl that expects this new file name.

Subject: [PATCH] [FEAT VS1804] genprotimg: add relocator for stage3b
From: Marc Hartmayer <mhartmay@linux.ibm.com>
Summary: genprotimg: Introduce new tool for the creation of PV images
Description: genprotimg takes a kernel, host-key documents, optionally an
initrd, optionally a file with the kernel command line, and it
generates a single, loadable image file. The image consists of a
concatenation of a plain text boot loader, the encrypted
components for kernel, initrd, and cmdline, and the
integrity-protected PV header, containing metadata necessary for
running the guest in PV mode. It's possible to use this image file
as a kernel for zIPL or for a direct kernel boot using QEMU.
Upstream-ID: d2f8f972cff7aacbef8e72577af70dbf59ba3ead
Problem-ID: VS1804
Upstream-Description:
genprotimg: add relocator for stage3b
Add support for the placement of the stage3b loader at other addresses
than 0xa000. For this add a position independent relocator that first
copies the original stage3b code to the memory location 0xa000 and
then starts it.
