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/reboot.h

Detected Declarations

• struct irq_data
• struct platform_device
• struct pt_regs
• struct clk
• struct device_node
• struct of_device_id
• enum mxc_cpu_pwr_mode
• enum mxc_cpu_pwr_mode
• enum ulp_cpu_pwr_mode
• function imx_scu_map_io
• function imx53_suspend

Annotation

• Immediate include surface: `linux/reboot.h`.
• Detected declarations: `struct irq_data`, `struct platform_device`, `struct pt_regs`, `struct clk`, `struct device_node`, `struct of_device_id`, `enum mxc_cpu_pwr_mode`, `enum mxc_cpu_pwr_mode`, `enum ulp_cpu_pwr_mode`, `function imx_scu_map_io`.
• 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.
