Update the NEORV32 SoC, peripheral drivers, and board to support NEORV32 v1.11.1. Notable changes include: - Optional RISC-V ISA Kconfigs are now selected on the board level. - Peripheral registers are now automatically reset in hardware, no need for software initialization code. - The NEORV32 GPIO controller now supports 32 pins, not 64. Interrupt support will be submitted in a separate PR. - Default board configuration has 64k RAM and is clocked at 18 MHz. Signed-off-by: Henrik Brix Andersen <henrik@brixandersen.dk> |
