Subject: [PATCH] [FEAT VS1804] zipl: move loaders layout definitions into separate header
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-Description:

zipl: move loaders layout definitions into separate header

Move the loaders (stage2/stage3) layout values to
             `include/boot/loaders_layout.h` and use the `_AC` macro for the
             constants. This allows the reuse of the definitions, e.g. in assembler
             files, and later for the creation of linker scripts.
