[PATCH 0/2] m68k/powerpc: Kill references to non-existent README.legal

[PATCH 0/2] m68k/powerpc: Kill references to non-existent README.legal

[Geert Uytterhoeven]

	Hi all,

Several source files contain license boilerplate that refers to the file
"README.legal", which never existed in upstream Linux.  This is a relic
from the early port of Linux to the m68k processor family, before it was
merged in v1.3.94.  Later, copies of this boilerplate ended up in the
PowerPC port.

The "README.legal" file (from e.g. [1]) read:

---8<-----------------------------------------------------------------
Legal information about the Linux/68k software package

All files contained in this archive are copyrighted by one or more
person.  They are not in the public domain.

Most of the files are copyrighted by Linus Torvalds, the original
writer of Linux for IBM PC clone systems.  Some parts are copyrighted
by other IBM PC linux developers.  Other parts are copyrighted by
Linux/68k developers.

This package is subject to the terms and conditions of the GNU General
Public License.  A copy of this license may be found in the file named
"COPYING" which should be in the same directory as this file.  If the
file has been omitted, you may obtain it by writing to the Free
Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
----------------------------------------------------------------->8---

Note that the "COPYING" file at that time corresponded to the version
from upstream Linux v0.99.11 until v2.1.104, and thus predated the
addition of the "only valid GPL version is v2" clause in v2.4.0-test8.

This patch series gets rid of the references to README.legal by
replacing the boilerplate with SPDX license identifiers.

Thanks for your comments!

[PATCH 1/2] m68k: Replace GPL 2.0+ README.legal boilerplate by SPDX

[Geert Uytterhoeven]

Upstream Linux never had a "README.legal" file, but it was present
in early source releases of Linux/m68k.  It contained a simple copyright
notice and a link to a version of the "COPYING" file that predated the
addition of the "only valid GPL version is v2" clause.

Get rid of the references to non-existant files by replacing the
boilerplate with SPDX license identifiers.
