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)
|
