[ARCH/RISC-V] Next RISC-V (#10320)

2026-10-17T01:44:26Z

* [libcpu][risc-v] Refactor the RISC-V architecture port Introduce an opt-in unified RISC-V common layer for RV32 and RV64 while keeping existing BSPs on the legacy implementation during migration. - use ARCH_RISCV and ARCH_CPU_64BIT for architecture and XLEN selection - unify context, trap, MMU, cache, timer, SBI, SMP and ISA handling - add PLIC, CLIC, ACLINT, APLIC and IMSIC support - map physical hart IDs to contiguous logical CPU IDs - add T-Head vendor overrides while preserving legacy ports - migrate qemu-virt64-riscv with RV32 and RV64 support - update clock_time, MM, LWP, OFW, PCI and Rust integration Existing BSPs continue using legacy_common or common64 unless they select RT_USING_RISCV_NEW_COMMON. Signed-off-by: GuEe-GUI <2991707448@qq.com> * [libcpu][risc-v] skip disabled CPU nodes in early FDT walk Rbb666 noted that rt_hw_fdt_install_early() walked every /cpus child without checking status, so disabled cores still joined hart registration and MMU capability probing. Skip nodes that are not okay/ok via rt_fdt_device_is_available() before reading reg or mmu-type.

feat(dm): support OFW on Cortex-M targets

2026-08-12T04:54:50Z

Add the ARM NVIC PIC driver, no-MMU I/O mapping, built-in FDT support, and Cortex-M CPU hooks required by the native RT-Thread device model.

[drivers][ofw] Update OFW #11004

2025-12-11T03:05:47Z

Fixup fdt address reg and cells parse. Support only option name way for earlycon. Find the console device when using "stdout-path".

[DM/FDT] Fix garble when booting

2025-04-14T10:04:39Z

Fix garble caused by empty implementation of earlycon series function in driver.If driver doesn't offer earlycon_id or rt_f dt_earlycon_id.setup function but open option, the checking of best_earlycon_id will failed. Signed-off-by: 1078249029 <1078249029@qq.com>

[DM/FDT] Fixup earlycon loss old messages.

2025-02-10T07:55:54Z

The `rt_fdt_scan_chosen_stdout` will init fdt_earlycon data without `msg` only, the `msg_idx` should not clean, too. Because we check if have old messages by `msg_idx` Signed-off-by: GuEe-GUI <2991707448@qq.com>

2024-09-19T13:16:56Z

1.Fixup `fdt_reserved_memory_reg` loop time. 2.Fixup `rt_fdt_translate_address` cells value reader. Signed-off-by: GuEe-GUI <2991707448@qq.com>

[FEATURE/FDT] Add bootargs select in early
