Previously k230 kernel build needs OpenSBI wrapping for use on target, thus leading to larger program and memory overheads. This patch adds alternative small overhead kernel build support. Changes: - in arch/risc-v/src/k230: - k230_head.S entrance renamed for sake of NUTTSBI - k230_irq.c add M-mode handling for NUTTSBI case - k230_mm_init.c add L3 table for smaller RAM case - hardware/k230_plic.h add PLIC_CTRL definition - Make.defs use CHIP_ASRCS to fix entrance selection - in boards/risc-v/canmv230/scripts: - Make.defs add support for NUTTSBI case Additions: - in boards/riscv/canmv230/: - scripts/ld-nuttsbi.script link script for NUTTSBI case - configs/nsbi/defconfig config for NUTTSBI case The artifact nuttx.bin from this configuration can be used directly on target as OpenSBI wrapping is not needed.
