* Revert "Remove coroutines (#874)"
This reverts commit 569c78fd8c.
* Update freertos Kernel submodule to latest head
* Remove temporary files
* Fix MingW demos and spell check
* Fix manifest version; fix headers
* Add ignore files and paths to core-checker.py
* Fix copyright in remaining files
* Fix PR check build failure
1. Remove defining `inline` in Makefile. This was causing build
warnings.
2. Ensure that the linker removed unused functions from various
compilation units.
3. Update the linker script so that all the functions are correctly
placed in FLASH section.
