This commit adds a "CONFIG_FREERTOS_USE_KERNEL_10_5_1" hidden option to enable
building of the v10.5.1 kernel for development/testing purposes. Currently
enabling this option will just cause CMake to error out.
Also added a markdown file to record the code changes made to the V10.5.1 source
when porting over SMP behavior.
This commit adds the source files for the FreeRTOS Kernel V10.5.1 in
preparation for upgrading ESP-IDF FreeRTOS Kernel version (files copied from
https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/V10.5.1)
The following modifications were made to the files when copying
- Added "SPDX-FileCopyrightText" and "SPDX-FileContributor" tags to all files
to pass ESP-IDF pre-commit checks.
- Left out some files unnecessary to ESP-IDF (e.g., URLs, "History.txt", and
"portable" folder).
