Yanfeng Liu a4b22fe999 risc-v/k230: initial Asymmetric Multi-Processing support ... K230 chip has two T-Head C908 RiscV cores, previously we run NuttX on either little or big cores. This patch runs NuttX on both cores with OpenAMP support via the RPTUN driver. New additions: - in arch/risc-v/src/k230 - k230_rptun.c K230 RPTUN driver - k230_rptun.h K230 RPTUN driver header file - in baords/risc-v/k230/canmv230 - configs/master Build config for master node - configs/remote Build config for remote node - scripts/ld-rptun.script Build script for RPTUN Major changes: - arch/risc-v/Kconfig Select NUTTSBI_LATE_INIT upon NUTTSBI - in arch/risc-v/include - k230/irq.h Add UART3 IRQ defs - in arch/risc-v/src/k230 - Kconfig Add RPTUN related config items - Make.defs Add k230-rptun.c to sources - hardware/k230_memorymap.h Add K230 device and CSR defs - k230_hart.c Add hart ctrl for RPTUN - k230_hart.h Add hart ctrl for RPTUN - k230_mm_init.c Add Svpmbt to support RPTUN - k230_start.c Revised to support RPMsg UART - in boards/risc-v/k230/canmv230 - scripts/Make.defs Add RPTUN script selection - src/canmv_init.c Add RPTUN and RPMsg_UART initialization - in Documentation/platforms/risc-v/k230/boards/canmv230 - index.rst Add AMP usage information.
