Yanfeng Liu 87c9a0ee76 risc-v/k230: add NUTTSBI based kernel build support ... 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.
