The full patman manual now lives with the standalone patch-manager
package, making the 1000-line copy in the tree redundant.
Remove the in-tree manual, its README and the doc/develop/patman.rst
toctree page.
The sending-patches guide already introduces patman, so point it at the
patch-manager package instead of the now-dead ':doc:' cross-reference
and, with the manual gone, add a couple of lines on how the tool works.
Point the SPI howto at that guide too, rather than repeating the install
details.

The b4 contributor guide sits in the coding-style document, which is an
odd place for it. Move it into sending_patches.rst, next to the patman
note, so both patch-sending tools are described together.
The b4_contrib label moves with it, so the reference from process.rst
still resolves.

The commit message for patch 1 explains what it is I'd like to be able
to do, but here's some more background:
For a long time, we've embedded the boot script in the U-Boot binary
by building a bootscript.itb, and using a .dtsi like
/ {
config {
bootscript = /incbin/("/path/to/bootscript.itb");
};
};
which in turn is mentioned in CONFIG_DEVICE_TREE_INCLUDES, that
bootscript.itb FIT image has been embedded in U-Boot's control
dtb. Running that was then a matter of doing
fdt addr ${fdtcontroladdr} && fdt get addr bsaddr /config bootscript && source ${bsaddr}
There are a couple of advantage of having the bootscript (and other
script logic) embedded in the U-Boot binary. First, there's no need to
figure out some separate partition to store the script in, and making
sure that gets updated whenever the bootloader itself does. Second,
one doesn't need to worry about verifying the script; whatever steps
one needs to take to implement secure boot for U-Boot itself will by
necessity also cover the control dtb (if nothing else then because
that's where the public key for the kernel verification lives). And
third, the boot script is automatically updated together with U-Boot
itself; and if U-Boot is stored in an eMMC boot partition, that update
is guaranteed to be atomic.
Now with the stricter requirements of libfdt starting from v2026.04,
the above command no longer worked, or only half the time, because the
embedded FIT image may not land on an 8-byte aligned address. So that
line had to be changed a little (line breaks added)
fdt addr ${fdtcontroladdr}
&& fdt get addr bsaddr /config bootscript
&& fdt get size bssize /config bootscript
&& cp.b ${bsaddr} ${loadaddr} ${bssize}
&& source ${loadaddr}
which is getting quite unwieldy.
Then it struck me that one could perhaps simplify all of this quite a
lot: Cut out the intermediate bootscript.itb, just create a .dtsi
which directly puts a /images node inside the control dtb
/ {
images {
default = "bootscript";
bootscript {
description = "Boot script";
data = /incbin/("/path/to/bootscript.sh");
type = "script";
compression = "none";
};
};
};
and treat the control dtb itself as a FIT image; so the command to put
in $bootcmd becomes simply
source ${fdtcontroladdr}:bootscript
and embedding other pieces of callable scripts is quite trivial.
And that almost works out-of-the-box, except for the fit_check_format() sanity check.
Introduce a CONFIG_ knob that allows one to opt out of those sanity
checks, for the special case of the address being checked being
identical to gd->fdt_blob.

Add a section that explains how one can embed scripts in the control
DTB and run them from the U-Boot shell, the advantages of doing that
compared to using a separately built FIT image, and the configuration
knob that must be turned on to allow this to work.

This series from James Hilliard <[email protected]> converts the
static flags list for the environment to be configured via Kconfig and
updates the documentation.
Link: https://lore.kernel.org/r/[email protected]
|
|
Environment callbacks can already be configured from Kconfig with
CONFIG_ENV_CALLBACK_LIST_STATIC, but static environment flags still
require board headers to define CFG_ENV_FLAGS_LIST_STATIC.
Add CONFIG_ENV_FLAGS_LIST_STATIC and use it as the only board-provided
static environment flags list. Convert the remaining default-config users
from CFG_ENV_FLAGS_LIST_STATIC to defconfig settings and drop the legacy
header macro from ENV_FLAGS_LIST_STATIC.
Move the environment flags format documentation out of README and into
the developer environment documentation. Include the format in the
Kconfig help as well.
This lets boards configure writeable-list policy and type validation
from defconfig without adding a config header solely for env flags.
This preserves the behavior of default configs. Header-only cases that
were inactive in upstream defconfigs are not converted into defconfig
entries: iot2050 can add its list when enabling ENV_WRITEABLE_LIST, and
smegw01 can add mmcdev:dw support if the unlocked SYS_BOOT_LOCKED=n
configuration is needed.

NET=y
In the past, we only had one network stack which was called NET. The
network features were enabled for the legacy (and then only) networking
stack since commit 22353fa6b585 ("bootstd: Add some default filesystems
and commands"). Then instead on relying on NET legacy stack for enabling
networking features, the dependencies were (mostly) changed to depend on
CMD_NET in commit a0c739c184ca ("boot: Create a common BOOT_DEFAULTS for
distro and bootstd"). Then a new stack (lwIP) appeared, then CMD_NET was
made available with this new stack in commit 98ad145db61a ("net: lwip:
add DHCP support and dhcp commmand") making the networking features
possible to enable and finally commit f1e978fd54d9 ("boot: Update tests
around network symbols in BOOT_DEFAULTS_CMDS") made it explicit that we
need *a* network stack to enable some networking features.
Align the bootstd documentation with what's actually implemented as
Kconfig dependencies. Note that BOOTSTD_DEFAULTS selects BOOT_DEFAULTS
which selects BOOT_DEFAULTS_CMDS which then selects network features.
The CMDLINE symbol needs to be enabled as well for BOOT_DEFAULTS to
select BOOT_DEFAULTS_CMDS, but I don't think we need to go that far into
explaining what's required to enable some commands.

Quentin Schulz <[email protected]> says:
This migrates the net options away from the main Kconfig to net/Kconfig,
rename the current NET option to NET_LEGACY to really highlight what it
is and hopefully encourage more people to use lwIP, add a new NET
menuconfig (but keep NO_NET as an alias to NET=n for now) which then
allows us to replace all the "if legacy_stack || lwip_stack" checks with
"if net_support" which is easier to read and maintain.
The only doubt I have is wrt SYS_RX_ETH_BUFFER which seems to be needed
for now even when no network is configured? Likely due to
include/net-common.h with PKTBUFSRX?
No change in behavior is intended. Only change in defconfig including
other defconfigs where NO_NET=y or NET is not set, in which case NO_NET
is not set or NET=y should be set in the top defconfig. Similar change
required for config fragments. See commit log in patch adding NET
menuconfig for details.
This was tested based on 70fd0c3bb7c2 ("x86: there is no
CONFIG_UBOOT_ROMSIZE_KB_12288"), from within the GitLab CI container
trini/u-boot-gitlab-ci-runner:noble-20251013-23Jan2026 and set up
similarly as in "build all platforms in a single job" GitLab CI job.
#!/usr/bin/env bash

./tools/buildman/buildman -o ${O} $ARGS -Ssd $*
O=../build/u-boot/ ../u-boot.sh -b master^..b4/net-kconfig |& tee ../log.txt
I can't really decipher the log.txt, but there's no line starting with
+ which would be an error according to tools/buildman/builder.py help
text. Additionally, because I started the script with set -e set and
because buildman has an exit code != 0 when it fails to build a board,
and I have the summary printed (which is the second buildman call), I
believe it means all builds passed.
The summary is the following:
aarch64: (for 537/537 boards) all +0.0 rodata +0.0
uniphier_v8 : all +1 rodata +1
u-boot: add: 0/0, grow: 1/0 bytes: 1/0 (1)
function old new delta
data_gz 10640 10641 +1
arm: (for 733/733 boards) all -0.0 rodata -0.0
uniphier_v7 : all -1 rodata -1
u-boot: add: 0/0, grow: 0/-1 bytes: 0/-1 (-1)
function old new delta
data_gz 11919 11918 -1

data_gz 18778 18775 -3
uniphier_ld4_sld8: all -3 rodata -3

u-boot: add: 0/0, grow: 0/-1 bytes: 0/-20 (-20)
function old new delta
data_gz 15783 15763 -20
As far as I could tell this data_gz is an automatically generated array
when CONFIG_CMD_CONFIG is enabled. It is the compressed .config stored
in binary form. Because I'm changing the name of symbols, replacing a
menu with a menuconfig, additional text makes it to .config and the
"# Networking" section in .config disappears.
Here is the diff for the 5 defconfigs listed above, generated with:
for f in build/*-m; do
diff --unified=0 $f/.config $(dirname $f)/$(basename -a -s '-m' $f)/.config
done
(-m is the build directory for master, and without the suffix, it's the
top commit of this series)

Highlight that NET really is the legacy networking stack by renaming the
option to NET_LEGACY.
This requires us to add an SPL_NET_LEGACY alias to SPL_NET as otherwise
CONFIG_IS_ENABLED(NET_LEGACY) will not work for SPL.
The "depends on !NET_LWIP" for SPL_NET clearly highlights that it is
using the legacy networking app so this seems fine to do.
This also has the benefit of removing potential confusion on NET being a
specific networking stack instead of "any" network stack.
