Allwinner A80 and A83T Security System crypto engine
Hardware crypto accelerator built into Allwinner's A80 and A83T application processors from around 2014, used in budget Android tablets and a handful of single-board computers like the NanoPi M3. It offloads symmetric ciphers and hashing from the ARM cores so those older SoCs can do bulk encryption without burning CPU.
recommendation
Worth keeping but documenting its niche, because the silicon it targets is a decade old and was never in mainstream products, yet the code is still being actively maintained upstream — a 2026 patch from Arnd Bergmann shows it remains in good repair rather than rotting. Removing it would break the small population of surviving A80/A83T boards (such as the NanoPi M3) that still run current kernels, while the maintenance burden looks low.

sun8i-ss still receives upstream maintenance in 2026; this patch updates the driver rather than removing it.
- linux-sunxi.org
Allwinner A83T is a 2014-era SoC; the page lists mostly older tablet/board devices, indicating aging hardware.
- linux-sunxi.org
Allwinner A80 is also a 2014-era SoC, reinforcing that the supported hardware family is old.

NanoPi M3 is a historical A83T board reference, consistent with limited surviving deployments rather than broad current-market use.
codex reasoning notes (technical)
Local exec_command inspection of drivers/crypto/allwinner/sun8i-ss/sun8i-ss-core.c shows the OF match table only for allwinner,sun8i-a83t-crypto and allwinner,sun9i-a80-crypto, so this driver targets older A83T/A80 SS blocks, not current H3/H5/H6 parts. lore_file_timeline produced the cited lore URL and shows fresh 2026 maintenance traffic with no obvious removal trend, so removal/deprecate is not justified. The linux-sunxi and FriendlyELEC URLs were obtained via web search and show the supported SoCs/boards are 2014-vintage and now niche; that supports low present-day deployment and a keep-annotate outcome rather than removal.
