[ANN] U-Boot v2026.04-rc1 released

[Tom Rini]

Hey all,

So it's release day and I have tagged and pushed things out.

First and foremost, this is a bit rougher than I would like but I hope
that doing the release will underscore the urgency of finishing some of
these fixes. We now require for our own use to be given a correctly (8
byte) aligned device tree. This is done in a lot of cases. However:
https://patchwork.ozlabs.org/project/uboot/patch/20260122172247.2995437-1-b-padhi@ti.com/#3640858
is needed to ensure that platforms that use a FIT image in the SPL phase
work.
https://patchwork.ozlabs.org/project/uboot/patch/20260120153314.95091-2-jamie.gibbons@microchip.com/
needs to be addressed further to fix the case of platforms which apply
overlays in FIT images (SPL or OS). This series also shows that if your
platform does not boot then SPL_MALLOC_F_LEN may be too small.
https://lore.kernel.org/u-boot/20260123161907.392211-1-festevam@gmail.com/
contains some of the discussion around the case of SPL *not* enabling
SPL_BSS_SEPARATE and so having an incorrectly sized empty BSS appeneded
to the image.

So, that's the important state of things right now. Some platforms are
broken. People helping to test the proposed fixes, or if needed, picking
up the changes and posting the next version of them, would be
appreciated.

We're continuing with a community meeting following the release and the
calendar link is

In terms of a rough changelog:
- We're on v6.17-dts for upstream device trees/bindings. The v6.18-dts
  tag will be too late for our release cycle so I expect people to be
  using the cherry-pick method to bring in dts changes as needed.
- Lots of platform updates. This is always the case with -rc1 and I
  never know which ones to emphasize.
  - That said, we've removed ATAGS support from some platforms as it's
    very legacy these days.
- Lots of fixing of issues reported by Smatch.
- We now support clang-format and prefer that over the old
  scripts/Lindent option for formatting code.
- Continued work on improving our old pre-rST docs and converting them
  to rST.
- Fixes in our DFU, MMC, PMIC, USB, UBI, SCMI, UEFI and networking
  subsystems.
- Some cleanups and improvements to Falcon mode, with the aim of being
  able to support this feature in secure boot contexts.
- More patches required for "allyesconfig" to build have been merged,
  but some are still outstanding.

I continue to plan to do an rc release every two weeks and the final
release will be 05 January 2026.

Thanks all!
