Does FreeRTOS support the new microcontrollers from Silabs that are ARM Cortex-M4 CPU based?

Hi - FreeRTOS supports ALL ARM Cortex-M0/M0+/M3/M4/M4F/M7  
microcontrollers from all manufacturers. That is because the FreeRTOS  
implementation does not have any dependencies that are outside of the  
Cortex-M core. You might have to create a project for it if there is  
not a pre-configured project in the download, that’s all.

Things to note: If you are using a Cortex-M4 without an FPU then use  
the Cortex-M3 port layer, and if you are using a Cortex-M7 with an R0p1  
core then use the M7 port layer, otherwise use the M4F port layer.
