7b41d6004a freertos: Fix idf_additions.h include order error
When building for CONFIG_FREERTOS_SMP, "idf_additions.h" was previously
implicitly included by "task.h" so that other ESP-IDF components still have
access to IDF API additions without needing to include "idf_additions.h"
directly.

However, some FreeRTOS headers (e.g., queue.h) will include task.h before
declaring any types (e.g., QueueHandle_t). Thus if any of those types are used
in idf_additions.h, we get a missing type error.

This commit moves the implicity include of idf_additions.h to FreeRTOS.h

6895e92fd2 freertos: Combine Amazon SMP FreeRTOS and IDF FreeRTOS config files
This commit merges the "FreeRTOSConfig_smp.h" file into the "FreeRTOSConfig.h".
The configurations for all FreeRTOS implementations are now stored in a single
file.

4f8c6c6277 freertos: Remove xTaskRemoveFromUnorderedEventList compatibility define
xTaskRemoveFromUnorderedEventList is a scheduler internal function, thus will
never be called by users. Therefore, the compatbility define is not necessary.

29ec3fbacf xtensa: Move default vectors back into xtensa_vectors.S
The default implementation of some xtensa vectors were previously moved to
"xtensa_vector_defaults.S" as weak functions so that they could be overriden.

This commit moves these default vectors back into "xtensa_vectors.S" in
preparation for further refactoring of the xtensa component.

e21ab0332b freertos(IDF): Refactor port heap functions
Vanilla FreeRTOS expects applications to use one of the heap implementations
provided by FreeRTOS (i.e., heap_x.c), where functions such as pvPortMalloc()
and vPortFree() are defined in the heap implementation.

However, ESP-IDF already provides its own heap implementation
(i.e., esp_heap_caps.h). Thus, the pvPortMallc()/vPortFree() functions were
previously overriden by macro to call esp_heap functions directly.

This commit refactors the FreeRTOS port's heap as such:

- Added a heap_idf.c that implements all of the heap related functions required
  by FreeRTOS source
- All dynamic memory allocated by FreeRTOS is from internal memory. Thus, the
  FreeRTOS heap is the internal memory subset of the ESP-IDF heap.
- Removed some old macros to reduce diff from upstream source code.

9300bef9b8 freertos(SMP): Refactor FPU handling on the Xtensa port of Amaazon SMP FreeRTOS
This commit refactors the FPU handling code on the Xtensa port of Amazon SMP
FreeRTOS in the following ways:

Auto-pinning via XT_RTOS_CP_EXC_HOOK
------------------------------------

The "_xt_coproc_exc" exception would previously automatically pin a task that
uses the FPU to the current core (to ensure that we can lazy save the task's FPU
context). However, this would mean that "xtensa_vectors.S" would need to be
OS-aware (to read the task's TCB structure).

This is now refactored so that "_xt_coproc_exc" calls a CP exception hook
function ("XT_RTOS_CP_EXC_HOOK") implemented in "portasm.S", thus allowing
"xtensa_vectors.S" to remain OS agnostic.

Using macros to acquire owner spinlock
--------------------------------------

The taking and relasing of the "_xt_coproc_owner_sa_lock" is now mostly
abstracted as the "spinlock_take" and "spinlock_release" macro. As a result,
"_xt_coproc_release" and "_xt_coproc_exc" are refactored so that:

- They are closer to their upstream (original) versions
- The spinlock is only taken when building for multicore
- The spinlock held region is shortened (now only protects the instructions
  that access the "_xt_coproc_owner_sa" array

Other Changes
-------------

- Updated placing and comments of various "offset_..." constants used by
  portasm.S
- Update description of "get_cpsa_from_tcb" assembly macro
- Tidied up some typos in the ".S" files

fd48daf278 freertos(SMP): Fix SMP FreeRTOS Xtensa port FPU/Coproccessor bugs
This commit fixes the following FPU/Coprocessor bugs in the Xtensa port of
Amazon SMP FreeRTOS:

- vPortCleanUpCoprocArea() does not calculate the correct pointer to the
task's CPSA (located on the task's stack). This can result in
    - _xt_coproc_release() not releasing the task's CP ownership
    - The next coprocessor exception will write the current CP owner (i.e., the
      deleted task's CPSA) leading to memory corruption
- _xt_coproc_release() writes xCoreID instead of 0 when clearing a CP owner.
  This results in the next CP exception trying to load the CP owner's CPSA at
  the address of "xCoreID", leading to a double exception.

486cc33fb3 freertos: Refactor port common functions

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.

816ddc8867 freertos(SMP): Fix SMP FreeRTOS portDISABLE_INTERRUPTS() macro on xtensa port
The portDISABLE_INTERRUPTS() macro on Xtensa should return only the interrupt
mask/level before the interrupts were disabled. Previously, the entire contents
of PS register were returned (i.e., direct return from RSIL instruction without
any bit masking or shifting).

This commit fixes the portDISABLE_INTERRUPTS() macro to return the INTLEVEL
bitfield of the PS register.

The following changes have been made in this commit:
1. configMINIMAL_STACK_SIZE is now defined as CONFIG_FREERTOS_IDLE_TASK_STACKSIZE.
2. Removed configIDLE_TASK_STACK_SIZE config as it was redundant.
3. Updates the order of allocating the TCB and stack memory to avoid the
   stack memory overriding the TCB memory when the stack grows downwards.
4. CONFIG_FREERTOS_IDLE_TASK_STACKSIZE is now incorporated into the
   FreeRTOSConfig_smp.h to configure the IDLE0 stack size.

  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.

0cf1fd3a5a freertos: Add multi-core OS startup race condition workaround
FreeRTOS uses a single "xSchedulerRunning" variable to tack whether the
scheduler has started, and this variable is set to "pdTRUE" by core 0
via calling vTaskStartScheduler().

However, with SMP FreeRTOS, there is a race condition where core 0 has
already started the scheduler and another core has not called xPortStartScheduler()
yet and calls some FreeRTOS API. Thus the resultant FreeRTOS API can
cause errors as it thinks the scheduler has started.

This commit adds a temporary workaround (by having each core maintain their
own "xSchedulerRunning" variable.
