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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.

Dependency Surface

• linux/init.h
• linux/kernel.h
• linux/pci.h
• mach/fpga.h

Detected Declarations

• function pcibios_setup
• function sdk7786_pci_init

Annotated Snippet

if ((data & PCIECR_PRST3) == 0) {
			pr_warn("Unreachable card detected in slot#3\n");
			return -EBUSY;
		}
	} else
		pr_info("PCIe slot#4 disabled\n");

	return 0;
}
postcore_initcall(sdk7786_pci_init);

Annotation

• Immediate include surface: `linux/init.h`, `linux/kernel.h`, `linux/pci.h`, `mach/fpga.h`.
• Detected declarations: `function pcibios_setup`, `function sdk7786_pci_init`.
• Atlas domain: Architecture Layer / arch/sh.
• Implementation status: integration 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.
