ARM: Add a neon-intrinsics.h header like on arm64

2026-05-28T20:14:17+00:00

Add a header asm/neon-intrinsics.h similar to the one that arm64 has. This makes it possible for NEON intrinsics code to be shared seamlessly between ARM and arm64.

ARM: zte: Add zx297520v3 platform support

2026-05-13T20:59:56+00:00

This SoC is used in low end LTE-to-WiFi routers, for example some D-Link DWR 932 revisions, ZTE K10, ZLT S10 4G, but also models that are branded and sold by ISPs themselves. They are widespread in Africa, China, Russia and Eastern Europe. This SoC is a relative of the zx296702 and zx296718 that had some upstream support until commit 89d4f98ae90d ("ARM: remove zte zx platform"). Reviewed-by: Linus Walleij Reviewed-by: Krzysztof Kozlowski Signed-off-by: Stefan Dösinger --- Patch changelog: v8: * Select ARM_PSCI_FW (Sashiko). This is an issue make defconfig pointed out in the last patch in this series. The board does not have PSCI firmware as far as I can tell, but the ARM_GIC_V3 option indirectly assumes ARM_PSCI_FW is enabled. * Include in the board file for __initdata (Sashiko), removed other includes copypasted from another platform that aren't needed. Let's see if Sashiko agrees. * Add the SoC documentation to the documentation index (Sashiko) * Add the SoC documentation to MAINTAINERS (Sashiko) * Removed redundant if ARCH_ZTE (Sashiko) * Point towards a sane (USB-Only) U-Boot and modify the example code for booting from NAND to detect already fixed GIC setups.

Documentation: use a source-read extension for the index link boilerplate

2026-01-23T18:59:34+00:00

The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.
