Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/kernel.h
• linux/init.h
• linux/of_address.h
• linux/io.h
• linux/resource.h
• common.h

Detected Declarations

• function mvebu_cpu_reset_deassert
• function mvebu_cpu_reset_map
• function mvebu_cpu_reset_init

Annotated Snippet

			pr_warn(FW_WARN "deprecated pmsu binding\n");
			res_idx = 1;
		}
	}

	/* No reset node found */
	if (!np)
		return -ENODEV;

	ret = mvebu_cpu_reset_map(np, res_idx);
	of_node_put(np);

	return ret;

Annotation

• Immediate include surface: `linux/kernel.h`, `linux/init.h`, `linux/of_address.h`, `linux/io.h`, `linux/resource.h`, `common.h`.
• Detected declarations: `function mvebu_cpu_reset_deassert`, `function mvebu_cpu_reset_map`, `function mvebu_cpu_reset_init`.
• 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.
