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

lib: utils/hsm: Add SiFive TMC0 driver

2025-10-28T05:58:03Z

The SiFive TMC0 controls the tile power domains on SiFive platform. The CPU enters the low power state via the `CEASE` instruction after configuring the TMC0. Any devices that inside the tile power domain will be power gated, including the private cache. Therefore flushing the private cache before entering the low power state.

lib: utils: Initialize miscellaneous drivers in one pass

2025-02-12T16:09:25Z

For driver subsystems that are not tightly integrated into the OpenSBI init sequence, it is not important that the drivers are initialized in any particular order. By putting all of these drivers in one array, they can all be initialized with a single pass through the devicetree. This saves about 10 ms of boot time on HiFive Unmatched.
