Annotated Snippet
The SMC registers are used to configure Atmel EBI (External Bus Interface)
to interface with standard memory devices (NAND, NOR, SRAM or specialized
devices like FPGAs).
Required properties:
- compatible: Should be one of the following
"atmel,at91sam9260-smc", "syscon"
"atmel,sama5d3-smc", "syscon"
"atmel,sama5d2-smc", "syscon"
"microchip,sam9x60-smc", "syscon"
"microchip,sam9x7-smc", "atmel,at91sam9260-smc", "syscon"
- reg: Contains offset/length value of the SMC memory
region.
Example:
smc: smc@ffffc000 {
compatible = "atmel,sama5d3-smc", "syscon";
reg = <0xffffc000 0x1000>;

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.
