CONFIG_SOC_SERIES_NEORV32

NEORV32 Processor

Type: bool

Help

Enable support for the 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)
