Re: [PATCH v2 2/2] powerpc: Replace GPL 2.0+ README.legal boilerplate with SPDX

Geert Uytterhoeven [off-list ref] writes:

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-existent files by replacing the
boilerplate with SPDX license identifiers.
