Annotation

• Immediate include surface: `linux/errno.h`, `asm/cputype.h`.
• Detected declarations: `function scu_a9_has_base`, `function scu_a9_get_base`, `function scu_get_core_count`, `function scu_power_mode`, `function scu_cpu_power_enable`, `function scu_get_cpu_power_mode`, `function scu_enable`.
• Atlas domain: Architecture Layer / arch/arm.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
