Annotated Snippet

AMCC NDFC (NanD Flash Controller)

Required properties:
- compatible : "ibm,ndfc".
- reg : should specify chip select and size used for the chip (0x2000).

Optional properties:
- ccr : NDFC config and control register value (default 0).
- bank-settings : NDFC bank configuration register value (default 0).

Notes:
- partition(s) - follows the OF MTD standard for partitions

Example:

ndfc@1,0 {
	compatible = "ibm,ndfc";
	reg = <0x00000001 0x00000000 0x00002000>;
	ccr = <0x00001000>;
	bank-settings = <0x80002222>;
	#address-cells = <1>;
	#size-cells = <1>;

	nand {
		#address-cells = <1>;
		#size-cells = <1>;

		partition@0 {
			label = "kernel";
			reg = <0x00000000 0x00200000>;
		};
		partition@200000 {
			label = "root";
			reg = <0x00200000 0x03E00000>;
		};
	};
};

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

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.
