* Added explicit cast to allow roll over and avoid integer promotion during cycles counters comparison in recmutex.c. * Fixed type mismatch between declaration and definition of function xAreSemaphoreTasksStillRunning( void ). * Added Atmel Studio demo projects for ATMega4809 and AVR128DA48. * Per https://www.freertos.org/upgrading-to-FreeRTOS-V8.html, I'm updating portBASE_TYPE to BaseType_t. Signed-off-by: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com> * Update register test for ATmega4809 - to cover r28, r29, r31. - call public API taskYIELD() instead of portYIELD(). * Update ATmega4809 readme.md to include info for serial port setup, and minor wording fix.
