Lee Lup Yuen 8e30c13441 arch/risc-v: Add support for SOPHGO SG2000 SoC (T-Head C906) ... This PR adds support for the SOPHGO SG2000 SoC, based on T-Head C906 64-bit RISC-V Core. This will be used by the upcoming port of NuttX for Milk-V Duo S SBC. Most of the code was derived from NuttX for Ox64 BL808. The source files are explained in the articles here: https://github.com/lupyuen/nuttx-sg2000 Modified Files in arch/risc-v: `Kconfig`: Added ARCH_CHIP_SG2000 for SG2000 SoC New Files in arch/risc-v: `include/sg2000/chip.h`: SG2000 Definitions `include/sg2000/irq.h`: External Interrupts `src/sg2000/chip.h`: Interrupt Stack Macro `src/sg2000/sg2000_allocateheap.c`: Kernel Heap `src/sg2000/sg2000_head.S`: Linux Header and Boot Code `src/sg2000/sg2000_irq.c`: Configure Interrupts `src/sg2000/sg2000_irq_dispatch.c`: Dispatch Interrupts `src/sg2000/sg2000_memorymap.h`: Memory Map `src/sg2000/sg2000_mm_init.c`, `sg2000_mm_init.h`: Memory Mgmt `src/sg2000/sg2000_pgalloc.c`: Page Allocator `src/sg2000/sg2000_start.c`: Startup Code `src/sg2000/sg2000_timerisr.c`: Timer Interrupt `src/sg2000/hardware/sg2000_memorymap.h`: PLIC and UART Base Address `src/sg2000/hardware/sg2000_plic.h`: PLIC Register Addresses `src/sg2000/Kconfig`: SG2000 Config `src/sg2000/Make.defs`: Makefile		2024-06-17 09:41:29 +08:00
