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.
* Added port layer from the FreeRTOS POSIX port, added
additional port code for ESP-IDF.
* Created another hello world example using that POSIX
port in tools/test_apps.
* Removed old linux app
This commit synchronizes multiple functions in tasks.c with upstream v10.4.3
that contain minor differences.
The following functions have had their parameter names or code formatting
updated:
- xTaskCreateStaticPinnedToCore()
- xTaskCreatePinnedToCore()
- prvInitialiseNewTask()
- prvTaskIsTaskSuspended()
- vTaskStartScheduler()
- xTaskResumeAll()
- xTaskCheckForTimeOut()
- uxTaskResetEventItemValue()
The following functions have had their missing "xAlreadyYielded" restored
- xTaskDelayUntil()
- vTaskDelay()
The following functions have had their critical section/interrupt disdable
usage update
- vTaskSuspendAll()
- xTaskGetTickCountFromISR()
- xTaskGetApplicationTaskTagFromISR()

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
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.
