This commit refactors the FreeRTOS configuration headers as follows:
- Layout is now similar to FreeRTOSConfig.h found in other upstream demos
- Separate out Vanilla FreeRTOS configurations and ESP-IDF additions
- Move/remove some irrelevant/unused macros and configurations
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.
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
These were called from IRAM context where the caller expect them to be inlined
and accessible when cache is disabled. This was not the case when compiled with -O0.

This commit does the following:
- Adds SPDX license identifiers to FreeRTOS sources. Remove those FreeRTOS sources from
the copyright ignore list.
- Update xtensa port files to match FreeRTOS v10.4.3. Added SPDX license identifiers
to the port files.
- Fixed some improperly licensed files
- Removed portbenchmark.h from RISC-V port
Upstream xtensa exception handling will save PS, PC, and a0 registers
together when saving a minimal context. This commit ppdates the xtensa
exception handling to match upstream behavior.
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.

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.
This commit removes the portmacro.h include from task.h as portmacro.h
gets pulled in via FreeRTOS.h. This aligns with upstream FreeRTOS code.

This commit updates the handles for the timer, task and event_group
modules to struct type. This matches upstream freertos source.

This issue was earlier fixed in commit 79e74e5d5f
but during migration to newer FreeRTOS release, it got introduced again.
This commit fixes thread safety issues with configASSERT() calls
regarding the value of uxSchedulerSuspended. A false negative
occurs if a context switch to the opposite core occurs in between
the getting the core ID and the assesment.

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
This function resets the spinlock given as a parameter after taking it
(when entering the critical section). This then results in a panic once
it tries to exit the same critical section.
* Closes https://github.com/espressif/esp-idf/issues/7725
The previous SMP freertos round robin would skip over tasks when
time slicing. This commit implements a Best Effort Round Robin
where selected tasks are put to the back of the list, thus
makes the time slicing more fair.
- Documentation has been updated accordingly.
- Tidy up vTaskSwitchContext() to match v10.4.3 more
- Increased esp_ipc task stack size to avoid overflow
Closes https://github.com/espressif/esp-idf/issues/7256
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.
