+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# During a first build the system will download many different source code tarballs
+# from various upstream projects. This can take a while, particularly if your network
+# connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
+# can preserve this directory to speed up this part of subsequent builds. This directory
+# is safe to share between multiple builds on the same machine too.
+#
+# The default is a downloads directory under TOPDIR which is the build directory.
+#
+#DL_DIR ?= "${TOPDIR}/downloads"
+
+#
+# Where to place shared-state files
+#
+# BitBake has the capability to accelerate builds based on previously built output.
+# This is done using "shared state" files which can be thought of as cache objects
+# and this option determines where those files are placed.
+#
+# You can wipe out TMPDIR leaving this directory intact and the build would regenerate
+# from these files if no changes were made to the configuration. If changes were made
+# to the configuration, only shared state files where the state was still valid would
+# be used (done using checksums).
+#
+# The default is a sstate-cache directory under TOPDIR.
+#
+#SSTATE_DIR ?= "${TOPDIR}/sstate-cache"
+
+#
+# Where to place the build output
+#
+# This option specifies where the bulk of the building work should be done and
+# where BitBake should place its temporary files and output. Keep in mind that
+# this includes the extraction and compilation of many applications and the toolchain
+# which can use Gigabytes of hard disk space.
+#
+# The default is a tmp directory under TOPDIR.
+#
+#TMPDIR = "${TOPDIR}/tmp"

+# Default policy config

+# This variable lists which packaging formats to enable. Multiple package backends
+# can be enabled at once and the first item listed in the variable will be used

+# Options are:
+#  - 'package_deb' for debian style deb files

+#  - 'package_rpm' for rpm style packages

+# We default to ipk:
+PACKAGE_CLASSES ?= "package_ipk"

+# This variable specifies the architecture to build SDK items for and means
+# you can build the SDK packages for architectures other than the machine you are

+#  "dbg-pkgs"       - add -dbg packages for all installed packages

+#  "src-pkgs"       - add -src packages for all installed packages

+#  "dev-pkgs"       - add -dev packages for all installed packages

+# process may require the user's attention. The default is iterate over the available
+# terminal types to find one that works.

+# to search other mirror locations for these objects before it builds the data itself.
+#
+# This can be a filesystem directory, or a remote url such as http or ftp. These
+# would contain the sstate-cache results from previous builds (possibly from other
+# machines). This variable works like fetcher MIRRORS/PREMIRRORS and points to the
+# cache locations to check for the shared objects.
+# NOTE: if the mirror uses the same structure as SSTATE_DIR, you need to add PATH
+# at the end as shown in the examples below. This will be substituted with the
+# correct path within the directory structure.

+
+#
+# Yocto Project SState Mirror
+#
+# The Yocto Project has prebuilt artefacts available for its releases, you can enable
+# use of these by uncommenting the following line. This will mean the build uses
+# the network to check for artefacts at the start of builds, which does slow it down
+# equally, it will also speed up the builds by not having to build things if they are
+# present in the cache. It assumes you can download something faster than you can build it
+# which will depend on your network.

+# Hash Equivalence
+#
+# Enable support for automatically running a local hash equivalence server and
