	  NEORV32 Processor (SoC).

	  The NEORV32 CPU implementation must have the following RISC-V ISA
	  extensions enabled in order to support Zephyr:
	  - M (Integer Multiplication and Division)
	  - Zicsr (Control and Status Register (CSR) Instructions)

	  The following NEORV32 CPU ISA extensions are not currently supported
	  by Zephyr and can safely be disabled:
	  - A (Atomic Instructions)
	  - E (Embedded, only 16 integer registers)
	  - Zbb (Basic Bit Manipulation)
	  - Zfinx (Floating Point in Integer Registers)
