-->To allow Cortex M7 accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded, containing '''m7''' label in the name, using the fdt_file environment variable in U-Boot.
 
This device tree disables some of the base device tree nodes in order to avoid conflicts between the main processor and Cortex M7.
