-      - Add support to allow the application writer to handle SVC calls raised
-        from the application code.
-      - Add support for vApplicationFPUSafeIRQHandler.
-    + POSIX port updates:
-      - Set PTHREAD_MUTEX_ROBUST attribute on the mutex to prevent application
-        hangs when a thread dies while holding a mutex.
-      - Avoid calling pthread_sigmask on non-FreeROS threads when
-        vPortEndScheduler is called from a non-FreeRTOS thread. We thank
-        @johnboiles for their contribution.
-      - Remove unnecessary call to pthread_attr_setstacksize. We thank
-        @hollinsky for their contribution.
-      - Add an assert to catch if vPortYield is called from a non-FreeRTOS
-        thread. We thank @johnboiles for their contribution.
-      - Fix Posix port compilation on FreeBSD. We thank @tymmej for their
-        contribution.
-    + Update the Xtensa port and move it to the Partner-Supported-Ports
-      repository. We thank @ianstcdns for their contribution.
-    + Add vPortGenerateSimulatedInterruptFromWindowsThread API in the MSVC-MingW
-      port to enable native windows thread to synchronize with FreeRTOS task
-      through simulated interrupt.
-    + Update Windows port to use Waitable Timer instead of Sleep to improve tick
-      accuracy. We thank @bknicholls and @leegeth for their contribution.
-    + Update the value of queueQUEUE_TYPE_SET to a unique value (5) to allow
-      tracers to differentiate between queues and queue sets. We thank @schilkp
-      for their contribution.
-    + Add traceSTARTING_SCHEDULER tracing hook to enable tracers to run code on
-      startup. We thank @schilkp for their contribution.

-      1. We thank @HazardyKnusperkeks for their contribution.
-    + Reset xNextTaskUnblockTime in task notify FromISR APIs to allow the core
-      to enter sleep mode at the earliest possible time when using tickless
-      idle.
-    + Optimize xTaskIncrementTick for SMP by removing xYieldRequiredForCore. We
-      thank @cymizer for their contribution.
-    + Update the SMP scheduler to re-select a core to yield when the core
-      affinity of a ready task is changed.
-    + Update xEventGroupSetBits to read the event bits value to be returned to
-      the caller while the scheduler is suspended. This fixes dereference after
-      the event group is deleted by higher priority task. We thank @skotopes for
-      their contribution.
-    + Optimize certain getter APIs by removing unnecessary calls to
-      task{ENTER|EXIT}_CRITICAL() when the data access is atomic. We thank
-      @GuilhermeGiacomoSimoes for their contribution.
-    + Optimize xTaskNotifyWait and ulTaskNotifyTake APIs to suspend the
-      scheduler only if the task is not already notified, and the caller is
-      willing to wait for the notification. We thank @jefftenney for
-      their contribution.
-    + Fix error checking of prvCreateIdleTasks. We thank @kakkoko for their
-      contribution.
-    + Update SMP lock macros and critical nesting macros to pass core ID as an
-      argument. This reduces the number of accesses to a peripheral register to
-      query core ID. We thank @felixvanoost for their contribution.
-    + Add stack pointer bounds check when configCHECK_FOR_STACK_OVERFLOW is set
-      to 2 to improve reliability of stack overflow detection. We thank

-    + Update run-time stats to include time elapsed since the last context
-      switch for the currently running task.
-    + Add xQueueCreateSetStatic API for static creation of Queue Sets. We thank
-      @kzorer for their contribution.

-      We thank @wdfk-prog for their contribution.
-    + Add pointer protection to the pxNextFreeBlock member of the allocated
-      block's metadata in heap_4 and heap_5 when configENABLE_HEAP_PROTECTOR is
-      set to 1. We thank @Saiiijchan for their contribution.
-    + Allow the application writer to override pointer validation for heap_5
-      when configENABLE_HEAP_PROTECTOR is used. We thank @Saiiijchan for their
-      contribution.
-    + Add xPortResetHeapMinimumEverFreeHeapSize to heap_4.c and heap_5.c.

-      @laroche for their contribution.
-    + Use _GNU_SOURCE macro instead of __USE_GNU in the Posix port. We thank
-      @maxiaogood for their contribution.
-    + Use the new __ARM_FP macro instead of the deprectred __VFP_FP__ macro in
-      GCC/ARM_CM7, GCC/ARM_CM4_MPU, and GCC/ARM_CM4F ports. We thank @haydenridd
-      for their contribution.
-    + Add portMEMORY_BARRIER definition to the Xtensa port. We thank @superroc
-      for their contribution.
-    + Move the hardware include msp430.h to port.c from portmacro.h. We thank
-      @mayl for their contribution.
-    + Update ARM assembly syntax for Cortex-M ports. We thank @laroche for their
-      contribution.
-    + Update the Windows port to records a pending yield in
-      vPortCloseRunningThread to ensure that the next tick interrupt schedules
-      the next task regardless of the value of configUSE_PREEMPTION.
-    + Fix the context switch issue in the RL78 port. We thank @KeitaKashima for
-      their contribution.
-    + Fix compilation issue in ARM CM0 port when using Keil MDK. We thank
-      @TomasGalbickaNXP for their contribution.
-    + Fix IA32 port compilation when configUSE_COMMON_INTERRUPT_ENTRY_POINT is
-      set to 0. We thank @Ryzee119 for their contribution.
-    + Store configMTIMECMP_BASE_ADDRESS in a 64-bit integer for the RISC-V port.

-      We thank @kilograham for their contribution.
-    + Fix the return value of portYIELD_FROM_ISR macro for the MSVC-MingW port.
-      We thank @wwhheerree for their contribution.
-    + Optimize vApplicationFPUSafeIRQHandler for the Coretex-A9 port by
-      removing the unnecessarily preserved callee saved registers. We thank
-      @Saiiijchan for their contribution.
-    + Fix the context array size for MPU ports to ensure the saved context
-      location falls within the reserved context area rather than overlapping
-      with the next MPU_SETTINGS structure member.
-    + Update CMake files for RP2040 port to fetch the port from the
-      Community-Supported-Ports repo. We thank @kilograham for their
-      contribution.
-    + Fix CMake file for the GCC ARM_CM0 port to include MPU files. We thank
-      @0mhu for their contribution.

- *
- * Note 2:  Blocking on a queue set that contains a mutex will not cause the

- *
- * Note 3:  An additional 4 bytes of RAM is required for each space in a every
- * queue added to a queue set.  Therefore counting semaphores that have a high
- * maximum count value should not be added to a queue set.
- *
- * Note 4:  A receive (in the case of a queue) or take (in the case of a

- * a call to xQueueSelectFromSet() has first returned a handle to that set member.
- *
- * @param uxEventQueueLength Queue sets store events that occur on
- * the queues and semaphores contained in the set.  uxEventQueueLength specifies
- * the maximum number of events that can be queued at once.  To be absolutely
- * certain that events are not lost uxEventQueueLength should be set to the
- * total sum of the length of the queues added to the set, where binary
- * semaphores and mutexes have a length of 1, and counting semaphores have a
- * length set by their maximum count value.  Examples:
- *  + If a queue set is to hold a queue of length 5, another queue of length 12,
- *    and a binary semaphore, then uxEventQueueLength should be set to
- *    (5 + 12 + 1), or 18.
- *  + If a queue set is to hold three binary semaphores then uxEventQueueLength
- *    should be set to (1 + 1 + 1 ), or 3.
- *  + If a queue set is to hold a counting semaphore that has a maximum count of
- *    5, and a counting semaphore that has a maximum count of 3, then
- *    uxEventQueueLength should be set to (5 + 3), or 8.
- *
- * @param pucQueueStorage pucQueueStorage must point to a uint8_t array that is
- * at least large enough to hold uxEventQueueLength events.
- *
- * @param pxQueueBuffer Must point to a variable of type StaticQueue_t, which
- * will be used to hold the queue's data structure.

- * @return If the queue set is created successfully then a handle to the created
- * queue set is returned.  If pxQueueBuffer is NULL then NULL is returned.

-# RH850/F1K and F1Kx FreeRTOS Port with CC-RH Compiler
-
-## Introduction
-
-This repository contains the port of FreeRTOS for Renesas RH850/F1K and F1Kx microcontrollers using the CC-RH compiler. The following sections provide instructions on how to use this port, a link to the test project, and other relevant information.
-
-## Prerequisites
-- Compiler: CC-RH
-- FreeRTOS version 11.1.0
-
-| Device   | FPU | SMP |
-|----------|-----|-----|
-| F1K      | Yes | No  |
-| F1KM-S1  | Yes | No  |
-| F1KM-S2  | Yes | No  |
-| F1KM-S4  | Yes | No  |
-| F1KH-D8  | Yes | Yes |
-
-## Link to Test Project
-
-The test project can be found [here](https://github.com/FreeRTOS/FreeRTOS-Community-Supported-Demos) (`RH850_F1Kx_CCRH`). This project contains example tasks and configurations to help you get started with FreeRTOS on the RH850/F1K and F1Kx.
-
-## Note
-   1. Configure IPIR Interrupt: Ensure that the bit specifying the destination for binding (requesting) an interrupt is enabled (e.g: IBDxxx register of F1KH-D8) (1)
-   2. `Channel 0` and address `0xFFFEEC00` are used as default configuration for configIPIR_CHANNEL and configEXCLUSIVE_ADDRESS, in case of resource confliction other channel/address can be used. (2)
-   3. The minimal stack size (configMINIMAL_STACK_SIZE) must be included the reserved memory for nested interrupt. This formula can be referred: `(task_context_size) * (2 + configMAX_INT_NESTING) + Stack_depth_of_taskcode`
-   In which, `task_context_size` is calculated as `36*4bytes = 144bytes` (when FPU enabled) or `34*4bytes = 136` (when FPU disabled), configMAX_INT_NESTING is `02` as default (Note that a value of `0` is not allowed).
-   4. `configTIMER_PRESCALE`: This value is required in order to correctly configure clock for `CPUCLK_L`. Refer to Hardware Manual at `Table 44.22` for `option byte`: If the user sets the option byte `CKDIVMD to 1`, then `configTIMER_PRESCALE = 4`. Otherwise, if `CKDIVMD is set to 0`, then `configTIMER_PRESCALE = 2`.
-
-(1)  This is applicable for F1KH-D8 with SMP only.
-
-(2) This is optional and applicable for SMP only.
-
-## Other Relevant Information
-
-- **Documentation:**
-  - Refer to the official [FreeRTOS documentation](https://www.freertos.org/Documentation/RTOS_book.html) for detailed information on configuring and using FreeRTOS.
