b5f2880261 Merge patch series "Clean up bloblist initialization"
Tom Rini <trini@konsulko.com> says:

This series does a few small but important cleanups to how we check for,
and initialize a bloblist. The first thing is that the way things are
done today, our HANDOFF code can only work with a fixed bloblist
location, so express that requirement in Kconfig. Next, we demote the
scary message about "Bloblist at ... not found" to a debug because we
most often see that because the bloblist doesn't (and can't) exist yet.
Finally, we remove bloblist_maybe_init and split this in to an exists
and a real init. This results in practically no growth (between 8 bytes
growth to 12 bytes saved, with some outliers saving much more thanks to
knowing it's impossible to have been passed a bloblist yet). This also
cleans up some of the code around checking for / knowing about a
bloblist existing.

5ab1600213 bloblist: Rework bloblist_init and bloblist_maybe_init
With bloblist, we need to both see if one already exists as well as
create one if it does not. However, the current implementation leads to
odd cases where we attempt to create a bloblist before this is possible
and have things be overly complicated when we are given one to work
with.

This reworks things to instead have a bloblist_exists function, which as
the name implies checks for an existing bloblist. This is used in
the case of booting, to see if we have one and in turn if we have a
device tree there as well as in the bloblist_init function to see if we
need to do anything.

In practical details, we move the logic from bloblist_init that was
checking for a bloblist to the new bloblist_exists function and then can
clarify the logic as it is much easier to state when we know we do not
have one rather than all the ways we might have one. Then we have the
locations that set gd->bloblist now also set the GD_FLG_BLOBLIST_READY
flag.

84a17fea21 imx: ahab: Use authenticated header for images loading
When loading container image, the container header is loaded into
heap memory. If ahab is enabled, the header is be copied to another
fixed RAM for authentication in ahab_auth_cntr_hdr. The better method
is using container header memory being authenticated for following
image loading.
So update ahab_auth_cntr_hdr to return the address of container header
being authenticated. Caller uses this header for following parsing
and image loading.

e3e651c480 Merge patch series "add memdup_nul(), use it and memdup() in a few places"
Rasmus Villemoes <ravi@prevas.dk> says:

There are quite a few places where we allocate X+1 bytes, initialize
the first X bytes via memcpy() and then set the last byte to 0.

The kernel has a helper for that, kmemdup_nul(). Introduce a similar
one, and start making use of it in a few places. Also the existing
memdup() helper can be put to more use.

There are lots more places one could modify. But for code shared with
host tools, one would need to do some refactoring, putting memdup()
and memdup_nul() in their own str-util.c TU which could then also be
included in the tools build.

719cacb92e stdio: drop stdio_clone
The helper stdio_clone only has a single caller, so it certainly
doesn't need to be public. But in fact, it is merely an open-coded
memdup() - which for some reason uses calloc() even if the whole

2c733e6c85 common: memsize: fix occasionally failing alias probing
probe_ram_size_by_alias() detects whether a probe address still aliases
a lower address by writing through one address and reading through the
other.

On i.MX95 this occasionally reported a false non-alias when the alias
read happened immediately after the write.

A memory barrier alone, mb(), was tested but did not make the failure go
away. This suggests that ordering the CPU accesses is not sufficient for
this probe, likely because the issue is in the path to the memory
controller rather than in the core itself.

Read the written address back before checking the alias address. This
appears to force the write to become observable at the probe address
before using the alias read to decide whether the tested address range
exists.

If the readback does not match the written pattern, restore the saved
value and continue with the next check. This keeps the probe robust for
addresses that do not reliably retain the test pattern.

96c8b9c4ce Merge patch series "net: migrate NO_NET out of the networking stack choice"
Quentin Schulz <foss+uboot@0leil.net> 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 70fd0c3bb7 ("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.

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.

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

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.

0977448b45 common: memsize: add RAM size probe based on alias detection
Add probe_ram_size_by_alias() to detect RAM size by checking whether a
write to one address aliases to another address.

Compared to get_ram_size(), this function allows the caller to:
- limit probing to a small set of required accesses
- avoid touching reserved or already used memory regions
- handle non-linear alias patterns

On the iMX95 SoC, when used with LPDDR5, accesses beyond the end of an 8GB DDR
configuration do not alias to the expected linear wrap-around addresses.
Instead, the aliased addresses appear to follow a pattern related to the
DDRC bank and bank-group addresses mapping. Experimentally, the observed
pattern is:

Write        Read
y00000000 -> x0001c000
y00004000 -> x00018000
y00008000 -> x00014000
y0000c000 -> x00010000
y00010000 -> x0000c000
y00014000 -> x00008000
y00018000 -> x00004000
y0001c000 -> x00000000

This helper makes it possible to probe RAM size by explicitly specifying
the probed address and the expected alias address for each size check.

052988aa29 Merge patch series "Linux compat improvements and CCF prep"
Casey Connolly <casey.connolly@linaro.org> says:

This series implements various improvements to Linux header
compatibility, largely in preparation for a full port of Linux CCF but
many of these changes would also be helpful when porting other drivers.

Beside the basic header/compat stuff there are a few larger patches:

Patch 1 adds the "%pOF" format specifier to vsprintf, this behaves the
same as it does in Linux printing the name of the ofnode, but notably it
expects an ofnode pointer rather than a device_node.

Patch 2 adds an option to skip doing a full DM scan pre-relocation.
Some platforms like Qualcomm don't actually need devices to be probed
prior to relocation, it is also quite slow to scan the entire FDT before
caches are up. This option gets us to main loop 30-50% faster.

Unfortunately it isn't possible to totally skip DM since U-Boot will
panic if it can't find a serial port, but the serial uclass code will
bind the serial port itself by reading /chosen/stdout-path, however any
dependencies like clocks won't be found so this should only be enabled
if the serial driver gracefully handles missing clocks.

Patch 3 adds [k]strdup_const(), this works the same as the Linux version
saving a small amount of memory by avoiding duplicating strings stored
in .rodata, this is particularly useful for CCF.

Patch 4 adds 64-bit versions of some 32-bit ofnode utilities functions,
making it possible to parse 64-bit arrays.

Patch 6 provides a simple implementation of kref, this will be used
by CCF.

Patch 9 adds devm_krealloc() support to devres, it relies on storing
allocation sizes in the devres struct which will add a small overhead.

f5e96fdffc common: add an option to skip DM pre-relocation
For some platforms like Qualcomm, it isn't necessary to perform a full
DM init and scan prior to relocation, it's also particularly slow since
it runs with dcache disabled and prior to building the livetree.

The only device which needs to be probed pre-reloc is the serial
port (otherwise U-Boot will panic), however this can be found through
/chosen/stdout-path.

Therefore we can avoid scanning the entire FDT and binding devices,
instead just binding the serial port and clock driver on-demand.

This decreases the total time from power on to reaching the interactive
U-Boot shell be about 50% (from ~2.8s to 1.8s).

32dc2866e0 console: Prefer currently selected serial console as stdio device
Adjust the scan for default console stdio device to prefer the
currently selected serial device. This is useful in combination
with CONFIG_SERIAL_PROBE_ALL=y, in which case the system would
instantiate all serial devices as stdio devices in the order in
which they are listed in control DT. The currently selected serial
device may not be the first device listed in DT, in which case the
current console_init_r() implementation unexpectedly switches to
another serial console after listing stderr using "Err:" line, and
just before showing U-Boot shell, which is not the desired behavior.

The scan now iterates over the entire list of stdio devices. If the
current iterator stdio device is the current serial device, or there
is no input or output stdio device assigned to the input or output
stream yet, then the current iterator stdio device is assigned to that
stream. This way, the first suitable stdio device is assigned to the
stream, but the current serial console stdio device can override that
assignment.

As a small optimization, if the current iterator stdio device is the
current serial device and both input and output streams as assigned,
then the loop can terminate, because the current serial device has a
chance to be used as a stdio device at this point.

d9eee3d178 arm: relocate: Introduce data-only relocation mode
Introduce new mode of relocation which relocates only data, not code.
This is mainly meant to relocate data to read-write portion of the RAM,
while the code remains in read-only portion of the RAM from which it is
allowed to execute. This split configuration is present on various secure
cores.

The result of the relocation is U-Boot running at its original address,
data relocated to the end of DRAM, but with added read-write area offset.
The U-Boot binary area is not reserved from the end of the DRAM in this
relocation mode, because U-Boot itself is not relocated.

e7ad95aa3f spl: spi: fix loss of spl_load() error on soft reset
When CONFIG_SPI_FLASH_SOFT_RESET is enabled, spi_nor_remove() is called
after spl_load() to switch the flash back to legacy SPI mode. However,
the return value of spi_nor_remove() unconditionally overwrites the
return value of spl_load(), discarding any load error.

Fix this by preserving the spl_load() error and only propagating the
spi_nor_remove() error as a fallback. Also log a message when
spi_nor_remove() fails, since in the case where spl_load() already
failed its error would otherwise be silently discarded.

Observed boot failure messages:
  Warning: Did not detect image signing certificate. Skipping authentication to prevent boot failure. This will fail on Security Enforcing(HS-SE) devices
  Authentication passed
  Starting ATF on ARM64 core...

The system then hangs. This indicates that without a data cache flush,
data in the cache is not coherent with RAM, preventing the system from
booting. This was verified by printing the content of this address when
the issue occurs.

Add a data cache flush after each restore operation to resolve this
issue.
