platform: generic: Optimize extensions_init() to parse ISA extensions once

2026-06-12T10:38:29Z

Instead of parsing ISA extensions separately for each hart in the generic_extensions_init() function, it is better to parse ISA extensions for all available harts in the cold boot path. Also, this allows us to remove fdt_isa_bitmap from scratch space and directly initialize "extensions" in struct sbi_hart_features for each hart.

lib: utils/hsm: factor out ATCSMU code into an HSM driver

2026-02-11T06:33:50Z

Refactor ATCSMU (System Management Unit) support by moving it from a system utility into a dedicated FDT-based HSM driver. Key changes include: - Moving the functions in lib/utils/sys/atcsmu.c into the new HSM driver - Moving hart start and stop operations on AE350 platform into the new HSM driver - Converting the assembly-based functions in sleep.S to C code for the readability - Updating the ATCWDT200 driver Signed-off-by: Ben Zong-You Xie Signed-off-by: Leo Yu-Chi Liang Link: https://lore.kernel.org/r/20251229071914.1451587-2-ben717@andestech.com Signed-off-by: Anup Patel

platform: generic: Modify platform ops instead of using hooks

2025-04-23T07:02:51Z

Switch all existing platform overrides to use the helper pattern instead of the platform hooks. After this commit, only the .match_table and .init members of struct platform_override are used. There are two minor behavioral differences: - For Allwinner D1, fdt_add_cpu_idle_states() is now called before the body of generic_final_init(). This should have no functional impact. - For StarFive JH7110, if the /chosen/starfive,boot-hart-id property is missing, the code now falls back to using generic_coldboot_harts, instead of accepting any hart.

platform: generic: andes: Remove inline definitions

2025-04-23T07:02:50Z

The addresses of these functions are used to set function pointers in struct platform_override, so it is not valid for them to be inline.

platform: generic: Pass FDT to early/final_init overrides

2024-08-24T07:32:54Z

Several of these override functions access the FDT blob. Explicitly indicate which callbacks are allowed to modify the FDT blob by passing the parameter as a possibly-const pointer. This also reduces code size by deduplicating the call to fdt_get_address(). Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel
