Is your feature request related to a problem? Please describe.
FreeRTOS version for nRF52840 is oudate. I am working with a nRF52840 with FreeRTOS distribution made by Adafruit: https://github.com/adafruit/Adafruit_nR ... 5/freertos

Describe the solution you'd like
The problem is that the version in this Github address is outdate, more especifically, it has just one Memory Management Heap Scheme: heap3.c. The version in the FreeRTOS.org has heap1.c, heap2.c, heap3.c, heap4.c and heap5.c. I need to work with heap4.c because it support dinamic memory allocation.
