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.

bac62cfac8 System: move interrupt stack to .bss instead of .data section
The interrupt stack for Xtensa targets is now declared in C, automatically moving it to .bss section instead of .data section.

* Closes https://github.com/espressif/esp-idf/issues/9188

7dc6fd9ff6 esp_system: Make interrupt WDT private API
This commit makes the interrupt WDT API private. To use the API,
IDF components should now '#include "esp_private/esp_int_wdt.h"'

57fd78f5ba freertos: Remove legacy data types
This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.

c5fd79547a freertos: Add CHOOSE_MACRO_VA_ARG selector
This commit adds a CHOOSE_MACRO_VA_ARG() selector to allow selection between two
versions of a macro based on the number of arguments. This replaces the previous
portGET_ARGUMENT_COUNT() selector.

- portYIELD_FROM_ISR() now uses CHOOSE_MACRO_VA_ARG()
- portYIELD_FROM_ISR(arg) version added to risc-v port
- Old vPortEvaluateYieldFromISR() and portGET_ARGUMENT_COUNT removed

e22b4007d3 esp_hw_support: Removed deprecated CPU util functions
The following files were deleted:
- components/esp_hw_support/include/soc/cpu.h
- components/soc/esp32s3/include/soc/cpu.h

The following functions are deprecated:
- get_sp()

The following functions declared in soc/cpu.h are now moved to esp_cpu.h:
- esp_cpu_configure_region_protection()

The following functions declared in soc/cpu.h are now moved to components/xtensa/include/esp_cpu_utils.h:
- esp_cpu_process_stack_pc()

All files with soc/cpu.h inclusion are updated to include esp_cpu.h instead.

5d32e80ea7 freertos: ensure interrupts are disabled before enabling tick timer
xPortStartScheduler calls vPortSetupTimer -> _frxt_tick_timer_init,
which enables tick timer interrupt and sets up the first timeout.
From that point on, the interrupt can fire. If the interrupt happens
while _frxt_dispatch is running, the scheduler will enter an infinite
loop. This is because _frxt_dispatch isn't supposed to be preemptable,
and the tick interrupt will overwrite some of the registers used by
_frxt_dispatch.
Note that this situation doesn't practically occur on the real
hardware, where the execution of vPortSetupTimer and _frxt_dispatch
happens quickly enough. However it can be reproduced on an emulator
if the tick period is set to 1ms.

Add an explicit call to portDISABLE_INTERRUPTS in xPortStartScheduler
to guarantee that _frxt_dispatch doesn't run with interrupts enabled.
This is similar to the esprv_intc_int_set_threshold(1); call in
RISC-V version of port.c.

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.

Closes https://github.com/espressif/esp-idf/issues/5301

4846222102 freertos: update freertos folder structure to match upstream
The following changes have been made:
1. All FreeRTOS kernel source files are now placed in the
   freertos/FreeRTOS-Kernel folder to match with the upstream folder structure.
2. All kernel include files are now placed in freertos/FreeRTOS-Kernel/include.
3. All port files are now placed in freertos/FreeRTOS-Kernel/portable.
4. All additions/customizations are placed in freertos/esp_additions.
5. All other miscellaneous files (README, License files etc.) are moved to
   freertos/FreeRTOS-Kernel folder to match with the upstream.
6. Updated esp-cryptoauthlib to latest commit to resolve FreeRTOS
   include dependencies.
