Hey all,
It's release day and here's v2025.04. We had some last minute issues
reported, but then also resolved. I want to thank everyone that's
contributed to this release, not just in terms of code, but
documentation, testing and otherwise ensuring things go as smoothly as
they can.
In terms of a changelog,
git log --merges v2025.04-rc5..v2025.04
contains what I've pulled since the last RC or:
git log --merges v2025.01..v2025.04
for changes since the last full release. As always, more details in
pull requests (or the tags referenced by them) will result in more
details here.
As is becoming reguarly scheduled, we have a community meeting tomorrow
(for me anyhow). The meeting details itself are:

Here are the notes from the meeting, please feel free to clarify any
points I might have missed or gotten wrong. Thanks Tom for chairing.
# U-Boot Community meeting April 8 2025
* Tom intro: next merged into master, small delay
* Heinrich: ACPI has regular regressions due to lack of testing in CI
* tom proposes adding another QEMU defconfig with ACPI enabled
* Heinrich: Ubuntu images being used in CI are getting too old
* tom: has a patch to update to GCC 14
* tom: opened an issue, Simon to investigate (link?)
* tom: already tested new GCC/LLVM, no new warnings.
* tom: will rebuild docker container this week, adding byacc for
binman to enable IMX8 testing
* state of Simons patches re: bootflow/EFI/standard boot
* issue with standard boot that the EFI bootmgr option is always at
the top
* heinrich: proposes a new virtual device that can be ordered anywhere
* heinrich will investigate in the next few weeks
* tom: modernising the Makefile
* tom: which platforms are still using old stuff? will consider
disabling or removing boards
* tom: e.g. watchdog (deadline 2019), legacy i2c (deadline 2022.04)
* caleb: FdtFile revival
* context: https://github.com/systemd/systemd/issues/36835
* would enable picking DTB matching your kernel version
* heinrich: robh thinks we should match on compatible instead. Simon
also agrees
* heinrich: fine with adding this patch
* simon: significant harm - compatible is the only right way to
match, anything else is a workaround
* caleb/tom: agrees in theory, but in practise this isn't what we
witness. Having a compressed blob of all DTs would be ideal, and
compresses well, but nobody is doing this..
* heinrich: U-Boot is also not the only firmware, we can't expect
EDK2 to start shipping this.
* Ilias: Agrees, best of the bad options
* simon: what would be the right solution?
* caleb: have the kernel emit a file with compatible -> fdtfile
lookups since that's faster to read
* Bryan Brattlof: what about overlays?
* caleb: probably you have a more vertically integrated system
* bryan: customers want yocto and a redhat image that works ootb
* tom/simon: bloblist:
* tom: if bloblist is enabled it MUST have the DT, set the "mandatory
passage flag"
* simon: OF_BLOBLIST means DT is in bloblist
* tom: it's a bad idea to divorce standard passage handoff from
bloblist, but if it eases some issues for now and we can revisit in a
~year that might be best
* ilias: we have discussed this before. doesn't think OF_BLOBLIST
should exist, because the info is discoverable at runtime.
* ilias: we have a standard (firmware handoff), why do we need
another implementation?
* tom: hoping to reconcile over time between fw handoff and bloblist
* tom: to re-iterate what Simon said: dt should be either in
bloblist, embedded, or discovered through board specific means. Need to
avoid conflating consuming bloblist and creating bloblist (e.g. in SPL).
* tom: in SPL, if we don't have a bloblist, we don't need a config
option.
* tom: we should remove BLOBLIST_FIXED
* simon: we can get rid of BLOBLIST_FIXED if we have a register
hand-off firmware (x86)
* out of time... Tom ok to add OF_BLOBLIST if we remove
BLOBLIST_FIXED. Hopes that in ~1 year we'll all agree that we want the
same thing...
The merge window is formally open again. I will be merging next in to
master shortly. The v2025.07 release is scheduled for Monday, July 7th,
2025 and the merge window will close and -rc1 will be released on the
28th of April, and then the next window will open with -rc2, two weeks
later. The keen-eyed among you might notice that I fixed some incorrect
-rc1 dates in the future planning section, including for this cycle.
Thanks all!
