Texas Instruments WiLink wl1251 Wi-Fi chipsets
An early Texas Instruments WiLink-family 802.11b/g Wi-Fi chip from the late 2000s, attached over SPI or SDIO and best known as the wireless radio in handheld Linux devices like the Nokia N900 smartphone and the OpenPandora gaming handheld.
recommendation
Worth keeping but documenting as legacy hardware. The chip is no longer sold through normal channels and only survives in hobbyist/retro devices like the N900 and OpenPandora (still actively used by communities such as Maemo Leste), but upstream is still cleaning the code up in 2025 and 2026 — replacing deprecated string functions and pruning dead code — so it is not a maintenance burden and removing it would strand a small but real user base.

codex reasoning notes (technical)
Local source inspection via shell (`sed`/`rg`) confirmed this is a real mac80211 driver for TI wl1251 with SPI and SDIO variants. Lore-first evidence: `lore_activity`/`lore_eq` showed recent upstream touches to wl1251 files in 2025; a direct `lore_file_timeline` on the directory returned no hits, likely due path-index granularity. A lore removal-regex attempt timed out, so I did not retry the same query; web search then found only dead-code cleanup and API-modernization patches, not a removal series. Deployment evidence came from web search hits for LKDDb, Pandora Wiki, Maemo Leste, and TI forum pages. Conclusion: hardware is legacy and likely not sold new in 2025, deployments are niche/low, but upstream still sees enough real maintenance that `deprecate` would be too aggressive; annotate as legacy instead.
