risc-v/canmv230: add PROTECTED build support
Additions: - In arch/risc-v/src/k230/ - k230_userspace.c add user space initialization - k230_userspace.h headers for user space initialization - In boards/risc-v/k230/canmv230/kernel/ - k230_userspace.c userspace_s const data definition - Makefile pass1 Makefile - In boards/risc-v/k230/canmv230/scripts/ - ld-protected.script linker script for protected build kernel - ld-userland.script linker script for protected build userspace - In boards/risc-v/k230/canmv230/configs - pnsh/defconfig defconfig for protected build Changes: - In arch/risc-v/src/k230/ - k230_start.c add protected build handling logic - Make.defs add protected build support - In boards/risc-v/k230/canmv230/scripts/ - Make.defs add protected build support - In Documentation/platforms/risc-v/k230/boards/canmv230/ - index.rst add protected build usage Signed-off-by: Yanfeng Liu <yfliu2008@qq.com>
