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

utils/reset: Remove fdt_reset_thead

2023-11-16T10:55:23Z

In the past, we used fdt_reset_thead to help customers with prototype verification. However, with the emergence of the Big-little SoC system, it can no longer meet the demand. Therefore, we use zero_stage_boot instead of fdt_reset_thead. It cleans up the opensbi code and ends the disputation of reset_sample's dts. This patch removes the fdt_reset_thead component and updates the related doc. Signed-off-by: Guo Ren Signed-off-by: Guo Ren Reviewed-by: Anup Patel
