in a single branch rather than individually, and only after changes are merged
in master, though exceptions for urgent cases could still be made.

[michael.opdenacker]

From: Michael Opdenacker <michael.opdenacker@bootlin.com>

In particular, this addresses multiple formatting issues.
Aligning with the master branch as all updates apply to
kirkstone too.

 Installing the Extensible SDK
 =============================
 
+Two ways to install the Extensible SDK
+--------------------------------------
+
+Extensible SDK can be installed in two different ways, and both have
+their own pros and cons:
+
+#. *Setting up the Extensible SDK environment directly in a Yocto build*. This
+   avoids having to produce, test, distribute and maintain separate SDK
+   installer archives, which can get very large. There is only one environment
+   for the regular Yocto build and the SDK and less code paths where things can
+   go not according to plan. It's easier to update the SDK: it simply means
+   updating the Yocto layers with git fetch or layer management tooling. The
+   SDK extensibility is better than in the second option: just run ``bitbake``
+   again to add more things to the sysroot, or add layers if even more things
+   are required.
+
+#. *Setting up the Extensible SDK from a standalone installer*. This has the
+   benefit of having a single, self-contained archive that includes all the
+   needed binary artifacts. So nothing needs to be rebuilt, and there is no
+   need to provide a well-functioning binary artefact cache over the network
+   for developers with underpowered laptops.
+
+Setting up the Extensible SDK environment directly in a Yocto build
+-------------------------------------------------------------------
+
+#. Set up all the needed layers and a Yocto :term:`Build Directory`, e.g. a regular Yocto
+   build where ``bitbake`` can be executed.
+
+#. Run::
+
+      $ bitbake meta-ide-support

+
+Patch Upstream Status
+=====================
+
+In order to keep track of patches applied by recipes and ultimately reduce the
+number of patches that need maintaining, the OpenEmbedded build system
+requires information about the upstream status of each patch.
+
+In its description, each patch should provide detailed information about the
+bug that it addresses, such as the URL in a bug tracking system and links
+to relevant mailing list archives.
+
+Then, you should also add an ``Upstream-Status:`` tag containing one of the
+following status strings:
+
+``Pending``
+   No determination has been made yet or not yet submitted to upstream.
+
+``Submitted [where]``
+   Submitted to upstream, waiting for approval. Optionally include where
+   it was submitted, such as the author, mailing list, etc.
+
+``Accepted``
+   Accepted in upstream, expect it to be removed at next update, include
+   expected version info.
+
+``Backport``
+   Backported from new upstream version, because we are at a fixed version,
+   include upstream version info.
+
+``Denied``
+   Not accepted by upstream, include reason in patch.
+
+``Inactive-Upstream [lastcommit: when (and/or) lastrelease: when]``
+   The upstream is no longer available. This typically means a defunct project
+   where no activity has happened for a long time --- measured in years. To make
+   that judgement, it is recommended to look at not only when the last release
+   happened, but also when the last commit happened, and whether newly made bug
+   reports and merge requests since that time receive no reaction. It is also
+   recommended to add to the patch description any relevant links where the
+   inactivity can be clearly seen.
+
+``Inappropriate [reason]``
+   The patch is not appropriate for upstream, include a brief reason on the
+   same line enclosed with ``[]``. The reason can be:
+
+   -  ``not author`` (you are not the author and do not intend to upstream this,
+      the source must be listed in the comments)
+   -  ``native``
+   -  ``licensing``
+   -  ``configuration``
+   -  ``enable feature``
+   -  ``disable feature``
+   -  ``bugfix`` (add bug URL here)
+   -  ``embedded specific``
+   -  ``other`` (give details in comments)
+
+The various ``Inappropriate [reason]`` status items are meant to indicate that
+the person responsible for adding this patch to the system does not intend to
+upstream the patch for a specific reason.
+
+Of course, if another person later takes care of submitting this patch upstream,
+the status should be changed to ``Submitted [where]``, and an additional
+``Signed-off-by:`` line should be added to the patch by the person claiming
+responsibility for upstreaming.
+
+For example, if the patch has been submitted upstream::
+
+   rpm: Adjusted the foo setting in bar
+
+   [RPM Ticket #65] -- http://rpm5.org/cvs/tktview?tn=65,5
+
+   The foo setting in bar was decreased from X to X-50% in order to

+
+   Upstream-Status: Submitted [rpm5-devel@rpm5.org]
+
+   Signed-off-by: Joe Developer <joe.developer@example.com>
+
+A future update can change the value to ``Accepted`` or ``Denied`` as
