Subject: [PATCH] [FEAT VS1804] zipl: refactor all EBCDIC code into separate files
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.

Problem-ID: VS1804
Upstream-Description:
zipl: refactor all EBCDIC code into separate files
This allows the reuse of the code later in sclp.c. While at it, also
declare @source parameter of `ebcdic_to_ascii` function as `const` and
rename all `ebc_` function name prefixes into `ebcdic_`. Move
conversion tables to separate file so it only gets linked into loaders
that need it.
