d2e4722f5b fix(freertos): Incorrect assert in FreeRTOS port layer when not in ISR context
This commit fixes an issue where in the FreeRTOS port layer would cause
the portASSERT_IF_IN_ISR() assert check to fail even when the system is
not in an interrupt context.

6eba7a536a feat(riscv): add support for PIE coprocessor and HWLP feature
FreeRTOS tasks may now freely use the PIE coprocessor and HWLP feature.
Just like the FPU, usiing these coprocessors result in the task being pinned
to the core it is currently running on.

824c8e0593 feat(esp_system): allow .bss to spill over into L2MEM above 0x4ff40000
This commit introduce SOC_MEM_NON_CONTIGUOUS_SRAM flag (that enebled for
esp32p4). If SOC_MEM_NON_CONTIGUOUS_SRAM is enabled:

- LDFLAGS+=--enable-non-contiguous-regions
- ldgen.py replaces "arrays[*]" from sections.ld.in with objects under
  SURROUND keyword. (e.g. from linker.lf: data -> dram0_data SURROUND(foo))
- "mapping[*]" - refers to all other data

If SOC_MEM_NON_CONTIGUOUS_SRAM, sections.ld.in file should contain at
least one block of code like this (otherwise it does not make sense):

  .dram0.bss (NOLOAD) :
  {
    arrays[dram0_bss]
    mapping[dram0_bss]
  } > sram_low

  .dram1.bss (NOLOAD) :
  {
    /* do not place here arrays[dram0_bss] because it may be splited
     * between segments */
    mapping[dram0_bss]
  } > sram_high

459ff8348f fix(riscv): Added RISC-V functions to set interrupt threshold for CLIC targets
This commit added the RISC-V utility functions to set the interrupt
threshold for CLIC targets by using direct register value writes.
This makes the functions more efficient during run-time.
This is done to improve the critical section enter and exit performance on esp32p4.

439c7c4261 change(freertos/idf): Remove xCoreID TCB member for single-core
This commit does the following:

- removes the xCoreID member from the TCB when building for single-core
- xCoreID is no longer hard set to 0 when calling "PinnedToCore" task creation
functions in single-core
- Tidy up or add missing xCoreID asserts for functions that take xCoreID as an
argument:
    - Functions that set/query a variable of a particular core will call
      taskVALID_CORE_ID() to ensure ) 0 <= xCoreID < configNUMBER_OF_CORES
    - Task creation functions that accept xCoreID also call taskVALID_CORE_ID()
      but also allow tskNO_AFFINITY.
- Fix TaskStatus_t
    - Remove xCoreID from TaskStatus_t if configTASKLIST_INCLUDE_COREID is not
      defined.
    - Set xCoreID to 0 when calling vTaskGetInfo() in single-core builds

a8b1475fe7 feat(riscv): implement coprocessors save area and FPU support
This commit mainly targets the ESP32-P4. It adds supports for coprocessors on
RISC-V based targets. The coprocessor save area, describing the used coprocessors
is stored at the end of the stack of each task (highest address) whereas each
coprocessor save area is allocated at the beginning of the task (lowest address).
The context of each coprocessor is saved lazily, by the task that want to use it.

Following the upgrade to FreeRTOS kernel v10.5.1, this commit updates the
version numbers, licenses, and SBOM files of FreeRTOS files to reflect v10.5.1.

Note:

- Updated licenses as v10.5.1 now uses SPDX format
- Removed CVE-2021-43997 as it was fixed post v10.4.5

57eb41ce83 refactor(freertos): Call TLSP deletion callback from portCLEAN_UP_TCB()
Previously, TLSP deletion callbacks were...

- Stored in a seprate TCB member "pvThreadLocalStoragePointersDelCallback"
- Called separately via multipole prvDeleteTLS() insertions in tasks.c

This commit refactors how TLSP deletion callbacks are stored and called:

- TLSP deletion callbacks are now stored in "pvThreadLocalStoragePointers"
directly. configNUM_THREAD_LOCAL_STORAGE_POINTERS is doubled in size so that
the deletion callbacks are stored in the latter half of the array

- The callbacks are now called via "portCLEAN_UP_TCB()". As such, the
prvDeleteTLS() additions are no longer needed and the function can be removed

- Removed some legacy TLSP tests using the old method of storing the callback
pointers.

This commit reduces the source code diff between IDF FreeRTOS and upstream
vanilla FreeRTOS, in preparation for v10.5.1 upgrade.

39cf3638ae change(freertos): Deprecate usage of vPortCleanUpTCB() by applications
Previously, if CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP was enabled, users
would provide a definition for a vPortCleanUpTCB() hook function that is called
right before a task's memory is freed in prvDeleteTCB(). However,
vPortCleanUpTCB() will be reclaimed by ESP-IDF for internal use in v6.0.

This commit introduces the following changes...

Introduced a new CONFIG_FREERTOS_TASK_PRE_DELETION_HOOK option:

- Provides the same pre-deletion hook functionality. But users now define
vTaskPreDeletionHook() instead.
- CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP still exists, but is marked as
deprecated. This is to maintain compatibility with existing applications
that already define vPortCleanUpTCB().
- Removed redundant --wl --wrap workaround with vPortCleanUpTCB()
- Added todo notes to remove support for user defined vPortCleanUpTCB()
completely in v6.0.
- Updated test cases to use new CONFIG_FREERTOS_TASK_PRE_DELETION_HOOK option

Freed up portCLEAN_UP_TCB() to call a new internal vPortTCBPreDeleteHook():

- vPortTCBPreDeleteHook() now replaces the previous "wrapped" implementation
of vPortCleanUpTCB().
- vPortTCBPreDeleteHook() is an internal task pre-delete hook for IDF FreeRTOS
ports to inject some pre-deletion operations.
- Internal pre-delete hook now invokes user provided vTaskPreDeletionHook()
if enabled.
- Relocated vPortTCBPreDeleteHook() to correct section in port.c

09690906e7 freertos: Refactor OS startup functions
This commit refactors the OS startup functions as follows:

- Moved the OS/app startup functions listed below to "app_startup.c". Their
    implementations are now common to all ports (RISC-V and Xtensa) of all
    FreeRTOS implementations (IDF and Amazon SMP).
    - esp_startup_start_app()
    - esp_startup_start_app_other_cores()
- Removed esp_startup_start_app_common() as app startup functions are now
    already common to all ports.
- Added extra logs to "main_task" to help with user debugging

Note: Increased startup delay on "unity_task". The "unity_run_menu()" is non
blocking, thus if the main task or other startup tasks have not been freed
by the time "unity_run_menu()" is run, those tasks will be freed the next time
"unity_task" blocks. This could cause some tests to have a memory leak, thus
the "unity_task" startup delay has increased.

fe0d4f2834 freertos: Refactor riscv port stack initialization code
This commit refactors the pxPortInitialiseStack() function of the riscv
FreeRTOS ports (both IDF and SMP FreeRTOS).

- Each stack area is now separated into their own functions
- Each function will individually
    - Push the stack pointer to allocate the stack area
    - Initiaze the allocated stack area
- Each stack area's size and usage is now clearly documented in code

This commit removes the riscv_interrupts.h header is it has become redundant. The previously
exposed API has been handled as follows:

- "riscv_interrupt_enable()" and "riscv_interrupt_disable()" have been removed. These functions
  were declarations only and never had any implementation.
- "riscv_global_interrupts_enable()" and "riscv_global_interrupts_disable()" renamed to
  "rv_utils_intr_global_enable()" and "rv_utils_intr_global_disable()" respectively and now
  placed in rv_utils.h

781d06af73 esp_hw_support: Remove compare_set.h API
This function removes the following legacy atomic CAS functions:

From compare_set.h (file removed):
- compare_and_set_native()
- compare_and_set_extram()

From portmacro.h
- uxPortCompareSet()
- uxPortCompareSetExtram()

Users should call esp_cpu_compare_and_set() instead as this function hides the details
of atomic CAS on internal and external RAM addresses.

Due to the removal of compare_set.h, some missing header includes are also fixed in this commit.

9b3796d2f1 freertos: Add portTRY_ENTRY_CRITICAL() and deprecate legacy spinlock fucntions
Add TRY_ENTRY_CRITICAL() API to all for timeouts when entering critical sections.
The following port API were added:
- portTRY_ENTER_CRITICAL()
- portTRY_ENTER_CRITICAL_ISR()
- portTRY_ENTER_CRITICAL_SAFE()

Deprecated legacy spinlock API in favor of spinlock.h. The following API were deprecated:
- vPortCPUInitializeMutex()
- vPortCPUAcquireMutex()
- vPortCPUAcquireMutexTimeout()
- vPortCPUReleaseMutex()

Other Changes:
- Added portMUX_INITIALIZE() to replace vPortCPUInitializeMutex()
- The assembly of the critical section functions ends up being about 50 instructions longer,
  thus the spinlock test pass threshold had to be increased to account for the extra runtime.
