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.

• linux/kernel.h
• linux/export.h
• linux/platform_device.h
• linux/err.h
• linux/clk.h
• bcm63xx_cpu.h
• bcm63xx_dev_spi.h
• bcm63xx_regs.h

Detected Declarations

• function bcm63xx_spi_register

		bcm63xx_spi_device.name = "bcm6358-spi",
		spi_resources[0].end += BCM_6358_RSET_SPI_SIZE - 1;
	}

	return platform_device_register(&bcm63xx_spi_device);
}

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.
