Subject: [PATCH] [FEAT VS1804] zipl: Consolidate STAGE{2,3} macros
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.

zipl: Consolidate STAGE{2,3} macros

Increase consistency with the other macros by moving and renaming
             the STAGE{2,3} macros in zipl.h.
