Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating. Jira: ZEP-1457 Change-Id: I6131a1d4ee0e58f5b938300c2d2fc77d2e69572c Signed-off-by: David B.

.. _synchronization_sample: Synchronization Sample ###################### Overview ======== A simple application that demonstates basic sanity of the kernel. Two threads (A and B) take turns printing a greeting message to the console, and use sleep requests and semaphores to control the rate at which messages are generated. This demonstrates that kernel scheduling, communication, and timing are operating correctly. Building and Running ==================== This project outputs to the console. It can be built and executed on QEMU as follows: .. code-block:: console $ cd samples/synchronization $ make run Sample Output ------------- .. code-block:: console threadA: Hello World! threadB: Hello World! threadA: Hello World! threadB: Hello World! threadA: Hello World! threadB: Hello World! threadA: Hello World! threadB: Hello World! threadA: Hello World! threadB: Hello World! <repeats endlessly>
