+BSP Build System
+****************
+
+The purpose of the build system is to produce and install artefacts from the
+RTEMS sources such as static libraries, start files, linker command files,
+configuration header files, header files, test programs, package description
+files, and third-party build system support files for a specific BSP in a user
+controlled configuration.
+
+Overview
+========
+
+The build system consists of three components which are all included in the
+RTEMS sources
+
+* the `waf <https://waf.io/>`_ meta build system command line tool,
+
+* a `wscript <https://git.rtems.org/rtems/tree/wcript>`_ file used by ``waf``,
+  and
+
+* a
+  `set of build specification items <https://git.rtems.org/rtems/tree/spec/build>`_
+  maintained by a text editor just like other source files.
+
+The build system is controlled by the user through
+
+* commands passed to the ``waf`` command line tool,
+
+* command line options passed to ``waf``, and
+
+* configuration files (e.g. ``config.ini``) used by ``wscript`` through ``waf``
+  invocations.
+
+Configurable things which are subject to a local installation variant such as
+paths to tools are intended to be passed as command line options to the ``waf``
+command line tool.  Which BSPs are built and how they are configured by means of
+options is placed in configuration files (e.g. ``config.ini``).  The
+configuration files may reside anywhere in the file system and the goal is to
+have it under version control by the user.
+
+Work Flow
+=========
+
+There are five steps necessary to build and install one or more BSPs.
+
+1. Select which BSPs you want to build.  See also :ref:`BSPs` and
+   ``./waf bsp_list``.
+
+2. Write a BSP build configuration file (e.g. ``config.ini``) which determines
+   which BSPs are built and how they are configured.
+
+3. Run the ``./waf configure`` command to generate the build
+   environment.
+
+4. Build the BSP artefacts with ``./waf``.  The build uses the build environment
+   created by ``./waf configure``.  The BSP build configuration file (e.g.
+   ``config.ini``) is no longer used and may be deleted.
+
+5. Install the BSP artefacts with ``./waf install``.
+
+Commands
+========
+
+The build system is controlled by invocations of the ``./waf`` command line
+tool instead of the well known ``make``.  Since waf is written in Python, a
+standard Python 2.7 or 3 installation without third-party packages is required
+to run it.  The ``./waf`` command line tool must be invoked in the RTEMS source
+tree top-level directory.
+
+Some commands accept the ``--rtems-specs`` command line option.  This option
+specifies paths to build specification items.  It is an advanced option and
+there is normally no need to use it.  It may be used to customize the build at
+the level of the build specification.  For more information see the
+`Build System` chapter of the
+`RTEMS Software Engineering <https://docs.rtems.org/branches/master/eng/build-system.rst>`_
+guide.
+
+Help
+----
+
+Use ``./waf --help`` to get a list of commands and options.
+
+BSP List
+--------
+
+The BSP list command ``./waf bsp_list`` loads the build specification items and
+generates a list of base BSPs from it.  The list is sorted by architecture and
+base BSP name.  Which base BSPs are listed can be controlled by the
+``--rtems-bsps`` command line option.  It expects a comma-separated list of
+`Python regular expressions <https://docs.python.org/3/library/re.html#regular-expression-syntax>`_
+which select the desired BSP variants.  The path to the build specification
+items can be specified by the ``--rtems-specs`` command line option.
+
+.. code-block:: none
+
+    $ ./waf bsp_list --rtems-bsps=sparc/
+    sparc/at697f
+    sparc/erc32
+    sparc/gr712rc
+    sparc/gr740
+    sparc/leon2
+    sparc/leon3
+    sparc/ut699
+    sparc/ut700
+
+.. code-block:: none
+
+    $ ./waf bsp_list --rtems-bsps='/leon,/rv64imac$'
+    riscv/rv64imac
+    sparc/leon2
+    sparc/leon3
+
+BSP Defaults
+------------
+
+The BSP defaults command ``./waf bsp_defaults`` loads the build specification
+items and generates a list options with default values for each base BSP from
+it.  The list is sorted by architecture and base BSP name.  Which base BSPs are
+listed can be controlled by the ``--rtems-bsps`` command line option.  Default
+values may depend on the selected compiler.  The compiler can be specified by
+the ``--rtems-compiler`` command line option.  The path to the build
+specification items can be specified by the ``--rtems-specs`` command line
+option.
+
+.. code-block:: none
+
+    $ ./waf bsp_defaults --rtems-bsps=gr712rc --rtems-compiler=gcc | grep ABI_FLAGS
+    ABI_FLAGS = -mcpu=leon3 -mfix-gr712rc
+
+.. code-block:: none
+
+    $ ./waf bsp_defaults --rtems-bsps=gr712rc --rtems-compiler=clang | grep ABI_FLAGS
+    ABI_FLAGS = -mcpu=gr712rc
+
+Configure
+---------
+
+The configure command ``./waf configure`` loads the BSP build configuration
+files and the build specification items and configures the build environment
+accordingly.  The configuration files can be specified by the ``--rtems-config``
+command line option.  It expects a comma-separated list of paths to the
+configuration files.  By default, the file ``config.ini`` is used.  The paths to
+RTEMS tools can be specified by the ``--rtems-tools`` command line option.  It
+expects a comma-separated list of prefix paths to tools, e.g.  compiler, linker,
+etc.  By default, the installation prefix is used for the RTEMS tools.  Tools
+are searched in the prefix path and also in a ``bin`` subdirectory of the prefix
+path.  The path to the build specification items can be specified by the
+``--rtems-specs`` command line option.
+
+Build, Clean, and Install
+-------------------------
+
+The commands ``./waf``, ``./waf clean``, and ``./waf install`` load the build
+specification items according to the specification paths stored in the build
+environment.  The BSP build configuration files (e.g. ``config.ini``) used by
+the ``./waf configure`` command to create the build environment are not longer
+used and may be deleted.  The build commands perform a dependency tracking and
+re-build artefacts if input sources changed.  Input sources are also the build
+specification.
+
+Configuration
+=============
+
+The BSP build configuration is done via INI-style configuration files.  The
+configuration files are consumed by the ``./waf configure`` command.  By
+default, the file ``config.ini`` is used.  You can specify other configuration
+files with the ``--rtems-config`` command line option.  The configuration files
+consist of sections and options (key-value pairs).
+
+To build a particular BSP, you have to create a section with the BSP variant
+name.
+
+.. code-block:: ini
+
+    [sparc/erc32]
+
+This one line configuration file is sufficient to build the base BSP
+`sparc/erc32` with default values for all options.  The base BSPs are determined
+by the build specification.  The ``./waf bsp_list`` command lists all base BSPs.
+You can create your own BSP names.  However, in this case you have to inherit
+from a base BSP.  The inheritance works only within an architecture, e.g. a
+`riscv` BSP cannot inherit options from an `arm` BSP.
+
+.. code-block:: ini
+
+    [sparc/foobar]
+    INHERIT = erc32
+
+The inheritance works recursively and must end up in a base BSP.
+
+.. code-block:: ini
+
+    [sparc/foo]
+    INHERIT = erc32
+
+    [sparc/bar]
+    INHERIT = foo
+
+A child BSP variant inherits all options from the parent BSP variant.  The child
+BSP can override the inherited options.
+
+You can determine the compiler used to build the BSP with the ``COMPILER``
+option.
+
+.. code-block:: ini
+
+    [sparc/gr740_gcc]
+    INHERIT = gr740
+    COMPILER = gcc
+
+    [sparc/gr740_clang]
+    INHERIT = gr740
+    COMPILER = clang
+
+Use the ``./waf bsp_defaults`` command to get a list of all configuration
+options with default values.
+
+.. code-block:: none
+
+    $ ./waf bsp_defaults --rtems-bsps=sparc/erc32
+    [sparc/erc32]
+    # Flags passed to the library archiver
+    ARFLAGS = crD
+    # Warning flags passed to the C compiler
+    CC_WARNING_FLAGS = -Wmissing-prototypes -Wimplicit-function-declaration -Wstrict-prototypes -Wnested-externs
+    # Warning flags passed to the C++ compiler
+    CXX_WARNING_FLAGS =
+    # Flags passed to the linker (GNU ld)
+    LDFLAGS = -Wl,--gc-sections
+    # Enable the Ada support
+    __RTEMS_ADA__ = False
+    # Enable the RTEMS internal debug support
+    RTEMS_DEBUG = False
+    ...
+    # Install the legacy application Makefile framework.
+    INSTALL_LEGACY_MAKEFILES = True
+
+It is not recommended to blindly add all the options obtained through the
+``./waf bsp_defaults`` command to custom configuration files.  The specified
+options should be kept at the necessary minimum to get the desired build.
+
+Some projects may still want to specify all options in a configuration file to
+be independent of changes in the base BSP.  You can review differences between
+the user and base BSP values with the ``diff`` command.
+
+.. code-block:: none

-Bootstrap the RTEMS Sources
-===========================
-
-You installed the tool suite in your installation prefix and made ready the
-source for two RTEMS source packages in the previous sections.  We installed
-the tool suite in :file:`$HOME/quick-start/rtems/5` and unpacked the RSB source
-in :file:`$HOME/quick-start/src`.
-
-You only need to *bootstrap* the RTEMS sources if you have used
-:ref:`QuickStartSources_Git` to get the sources. If you use source archives of
-a released RTEMS version you can skip this section and move to
-:ref:`QuickStartBSPBuild`.
-
-Before you can build a :ref:`Board Support Package (BSP) <BSPs>` for your
-target hardware from Git cloned RTEMS sources, you have to bootstrap the build
-system in the RTEMS sources.  This is only necessary if you use a Git
-repository clone of the RTEMS sources.  You have to do this after a fresh
-repository clone and sometimes after build system file updates (e.g.  after a
-``git pull``).  If you are not a build system expert, then do the bootstrap
-after each update of build system files.  This is a bit annoying, but improving
-the build system is a complex and time consuming undertaking.  Feel free to
-help the RTEMS Project to improve it.  For the bootstrap it is important that
-the right version of Autotools (:file:`autoconf` and :file:`automake`) are in
-your ``$PATH``.  The right version of Autotools is shipped with the RTEMS tool
-suite you already installed. Set the path to the tool suite installed under
-your selected *prefix*:
-
-.. code-block:: none
-
-    export PATH=$HOME/quick-start/rtems/5/bin:"$PATH"
-
-Change into the RTEMS source tree to *bootstrap* the build system:
-
-.. code-block:: none
-
-    cd $HOME/quick-start/src/rtems
-    ./rtems-bootstrap
-
