Why This File Exists
Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
- Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
- Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
- Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

MODULE_DESCRIPTION("MTD map driver for SBC-GXm and SBC-GX1 series boards");Annotation
- Immediate include surface: `linux/module.h`, `linux/ioport.h`, `linux/init.h`, `asm/io.h`, `linux/mtd/mtd.h`, `linux/mtd/map.h`, `linux/mtd/partitions.h`.
- Detected declarations: `function sbc_gxx_page`, `function sbc_gxx_read8`, `function sbc_gxx_copy_from`, `function sbc_gxx_write8`, `function sbc_gxx_copy_to`, `function cleanup_sbc_gxx`, `function init_sbc_gxx`, `module init init_sbc_gxx`.
- Atlas domain: Driver Families / drivers/mtd.
- Implementation status: integration implementation candidate.
- Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.
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.
