VIA/WonderMedia VT8500 and WM8xxx SoC info helper
A small support helper that identifies VIA/WonderMedia VT8500 and WM8xxx system-on-chips, an ARMv5/ARM11/Cortex-A9 family used in cheap Android tablets, netbooks, and set-top boxes during the early 2010s before WonderMedia was absorbed back into VIA in 2016.
recommendation
Worth keeping but flagging as legacy. Although the underlying VIA/WonderMedia tablet and netbook chips are early-2010s parts from a vendor that was folded back into VIA in 2016, the small SoC-info helper here was actually merged fresh in May 2025 and ships in current kernels (6.16 onward). It exists to keep the remaining supported legacy boards working, so removal would be premature, but a note that the hardware is long out of production would help future readers.

- lore.kernel.org
Mainline gained this driver in May 2025 as a new socinfo helper for VIA/WonderMedia SoCs, indicating current upstream maintenance rather than removal.
- lore.kernel.org
The merge commit references prior review/discussion on lore, showing active upstream review around the driver's introduction.
- cateee.net
LKDDb shows CONFIG_WMT_SOCINFO present in kernels 6.16-6.19 and 7.0-rc+HEAD, so the driver is current and not orphaned.
- en.wikipedia.org
WonderMedia SoCs are a legacy product line from a company founded in 2008 and merged into VIA in 2016; listed chips are early ARMv5/ARM11/Cortex-A9 tablet/netbook-era parts, supporting an obsolescence assessment.
codex reasoning notes (technical)
Directory contains a real platform driver (local shell inspection of wmt-socinfo.c/Kconfig). The two lore URLs were obtained from `git show` of the sole introducing commit, which links the patch posting and review thread; no removal discussion was present in the available lore-linked history. LKDDb URL was obtained via web search and confirms the config is in current kernels. Wikipedia URL was obtained via web search/open and supports that this is an old WonderMedia tablet/netbook SoC family from the early 2010s. Hardware appears legacy with low present-day deployments, but the driver was newly added in 2025 for still-supported legacy boards, so removal/deprecation would be premature; annotate as legacy instead.
