[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.

device node should not probe in stub if device is not available.

[DM/FEATURE] Support reset controller (#9630)

2024-11-26T02:02:50Z

* [DM/FEATURE] Support reset controller Reset controllers are central units that control the reset signals to multiple peripherals. The reset controller API is split into two parts: 1. The consumer driver interface, which allows peripheral drivers to request control over their reset input signals 2. The reset controller driver interface which is used by drivers for reset controller devices to register their reset controls to provide them to the consumers. * [RESET/SIMPLE] Support simple reset Currently this driver supports: - Altera SoCFPGAs - ASPEED BMC SoCs - Bitmain BM1880 SoC - Realtek SoCs - RCC reset controller in STM32 MCUs - Allwinner SoCs - SiFive FU740 SoCs - Sophgo SoCs Signed-off-by: GuEe-GUI <2991707448@qq.com>

[DM/FIXUP] Fixup CLK

2024-11-20T03:08:28Z

1. Default return OK when input NULL (if is not necessary in device). 2. Support object parse in OFW. 3. Support CLK depends fix auto. 4. Fixup rt_clk_array_prepare_enable and rt_clk_array_disable_unprepare. Signed-off-by: GuEe-GUI <2991707448@qq.com>

[FIXUP/OFW] ofw_parse_object fail

2024-09-13T21:33:29Z

The ofw parse should: 1. Check obj_name EQU the current node's rt_data. 2. Find the next object name. 3. goto "2" until obj_name EQU the cmp_cell's obj_name. Signed-off-by: GuEe-GUI <2991707448@qq.com>
