+as defined by the Linux Foundation's SPDX project [1].  For example,
+in a source file the full "GPL v2.0 or later" header text will be
+replaced by a single line:
+
+	SPDX-License-Identifier:	GPL-2.0+
+
+Ideally, the license terms of all files in the source tree should be
+defined by such License Identifiers; in no case a file can contain
+more than one such License Identifier list.
 
 If a "SPDX-License-Identifier:" line references more than one Unique
 License Identifier, then this means that the respective file can be
 used under the terms of either of these licenses, i. e. with
 
-	SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause
+	SPDX-License-Identifier:	GPL-2.0+	BSD-3-Clause
 
 you can choose between GPL-2.0+ and BSD-3-Clause licensing.
 
 We use the SPDX Unique License Identifiers here; these are available
 at [2].
 
-License identifier syntax
--------------------------
-
-1. Placement:
-
-   The SPDX license identifier in U-Boot files shall be added at the first
-   possible line in a file which can contain a comment.  For the majority
-   or files this is the first line, except for scripts which require the
-   '#!PATH_TO_INTERPRETER' in the first line.  For those scripts the SPDX
-   identifier goes into the second line.
-
-|
-
-2. Style:
-
-   The SPDX license identifier is added in form of a comment.  The comment
-   style depends on the file type::
-
-      C source:	// SPDX-License-Identifier: <SPDX License Expression>
-      C header:	/* SPDX-License-Identifier: <SPDX License Expression> */
-      ASM:	/* SPDX-License-Identifier: <SPDX License Expression> */
-      scripts:	# SPDX-License-Identifier: <SPDX License Expression>
-      .rst:	.. SPDX-License-Identifier: <SPDX License Expression>
-      .dts{i}:	// SPDX-License-Identifier: <SPDX License Expression>
-
-   If a specific tool cannot handle the standard comment style, then the
-   appropriate comment mechanism which the tool accepts shall be used. This
-   is the reason for having the "/\* \*/" style comment in C header
-   files. There was build breakage observed with generated .lds files where
-   'ld' failed to parse the C++ comment. This has been fixed by now, but
-   there are still older assembler tools which cannot handle C++ style
-   comments.
-
-|
-
-3. Syntax:
-
-   A <SPDX License Expression> is either an SPDX short form license
-   identifier found on the SPDX License List, or the combination of two
-   SPDX short form license identifiers separated by "WITH" when a license
-   exception applies. When multiple licenses apply, an expression consists
-   of keywords "AND", "OR" separating sub-expressions and surrounded by
-   "(", ")" .
-
-   License identifiers for licenses like [L]GPL with the 'or later' option
-   are constructed by using a "+" for indicating the 'or later' option.::
-
-      // SPDX-License-Identifier: GPL-2.0+
-      // SPDX-License-Identifier: LGPL-2.1+
-
-   WITH should be used when there is a modifier to a license needed.
-   For example, the linux kernel UAPI files use the expression::
-
-      // SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
-      // SPDX-License-Identifier: GPL-2.0+ WITH Linux-syscall-note
-
-   Other examples using WITH exceptions found in the linux kernel are::
-
-      // SPDX-License-Identifier: GPL-2.0 WITH mif-exception
-      // SPDX-License-Identifier: GPL-2.0+ WITH GCC-exception-2.0
-
-   Exceptions can only be used with particular License identifiers. The
-   valid License identifiers are listed in the tags of the exception text
-   file.
-
-   OR should be used if the file is dual licensed and only one license is
-   to be selected.  For example, some dtsi files are available under dual
-   licenses::
-
-      // SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause
-
-   Examples from U-Boot for license expressions in dual licensed files::
-
-      // SPDX-License-Identifier: GPL-2.0 OR MIT
-      // SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause
-
-   AND should be used if the file has multiple licenses whose terms all
-   apply to use the file. For example, if code is inherited from another
-   project and permission has been given to put it in U-Boot, but the
-   original license terms need to remain in effect::
-
-      // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) AND MIT
-
-   Another other example where both sets of license terms need to be
-   adhered to is::
-
-      // SPDX-License-Identifier: GPL-1.0+ AND LGPL-2.1+
