The TQMa6UL[L]x is a family of SoMs based on the i.MX6UL[L] SoCs.
They are available either with board connectors or as LGA packages
with solder balls. Add Support for the SoM and its combination with
our MBa6ULx carrier board. For use with the MBa6ULx carrier board,
the LGA variant is soldered onto an adapter board.

This series performs a general cleanup of the default U-boot environment
for sc5xx boards, stemming from the decision to no longer store the
environment in the SPI flash. The environments for each board have been
edited to contain the minimum number of commands needed for all supported
boot modes to avoid confusion, and the default boot command synced to spi
for all boards that support it. The filesystem for the SPI flash has also
been changed from jffs2 to ubifs.
A bug with the Ethernet reset line on the sc594 has been fixed, and the
sc573 has been renamed from the EZKIT to the EZLITE to match the name of the
publically available board. EZKIT was only used internally before release.
Preliminary binman support for sc5xx boards has been removed as it was unused
and full support never added.

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.

Add support for building U-Boot for Cortex-M33 RSIP core in Renesas
R-Car Gen5 R8A78000 X5H SoC. The main goal is to start U-Boot on the
Cortex-M33 RSIP core, which initializes the hardware and then starts
the Cortex-M33 SCP and Cortex-A720 cores which run the SCP firmware
and applications software respectively. The SCP is responsible for
platform resource management, and is used to start other CPU cores.
The Cortex-M33 build contains its own r8a78000_ironhide_cm33_defconfig
which configures the build for aarch32 instruction set compatible with
the ARMv8M core. The build also uses -cm33 DT and -u-boot.dtsi which
are derived from their non-CM33 counterparts, and add CM33 specifics.
The arch/arm/mach-renesas/u-boot-rsip.lds is derived from generic
arch/arm/cpu/u-boot.lds with adjustments to cater to the RSIP core,
those are entrypoint before vectors, __data_start/__data_end symbols
for data-only relocation, and placement of BSS into read-write SRAM
area.

Several boards use 'test -n ${var}' (unquoted) in env scripts to detect
an empty variable and trigger a fallback or skip a hook. That works only
because of a U-Boot 'test' quirk where calls with argc < 3 returned
false; an empty variable made the expression 'test -n' (one operand) and
hit that path.
Commit 8b0619579b ("cmd: test: fix handling of single-argument form of
test") aligned 'test' with POSIX so those expressions flipped to true.
f7e7c55e53 ("cmd: test: add bug-compatibility special case for 'test
-n'") restored the old behaviour for the exact 'test -n' (one arg) case,
so the boards are not broken at runtime today, but the reliance on a
bug-compat path isn't great.
This series updates various boards to quote each affected variable so
the emptiness check is explicit and does not depend on the
special-case path.

false to skip the run.

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

CONFIG_UBOOT_ROMSIZE_KB_12288"), from within the GitLab CI container
trini/u-boot-gitlab-ci-runner:noble-20251013-23Jan2026 and set up

I can't really decipher the log.txt, but there's no line starting with

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:

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.

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

The BOOTENV_DEV_UFS macro is incomplete - it only initializes UFS
and scans SCSI devices but does not actually boot anything. This
causes the boot sequence to stop after scsi scan without loading
a kernel.
Update BOOTENV_DEV_UFS to set the devnum environment variable to
the UFS instance number, initialize the device using $devnum, and
delegate the boot process to the shared scsi_boot script. Remove
the explicit scsi scan, as it is already handled by scsi_boot.
This matches the pattern used by other boot device macros and
ensures that UFS devices can successfully boot using the distro
boot framework.

With ENV_WRITEABLE_LIST only specific environment variables lisetd in
CFG_ENV_FLAGS_LIST_STATIC are read from the u-boot environment storage.
All other environment variables are set to default values and are not
written back to the storage.
The u-boot environment usually stays for the lifetime of the product.
There is no A/B copy mechanism as for the firmware itself. That means
that incompatible changes to environment variables in future u-boot

a new u-boot version or vice versa.
Having this protection in place ensures that only a limited set of
environment variables are persisted across u-boot versions. All the
macros not listed in CFG_ENV_FLAGS_LIST_STATIC are now part of the
u-boot binary which is redundant and immutable. This guarantees that
the u-boot version and the default values of these environment variables
are always in sync and cannot be changed at runtime.
ustate and rastate are not relevant for u-boot itself. ustate is used
by swupdate which persists the transaction state in the environment.
rastate is a similar variable used by another user space application.

STM32MP21 application processors (STM32 MPUs) based on a single
Arm Cortex®-A35 core running up to 1.5 GHz and Cortex®-M33 core
running at 300 MHz.
It is pin-compatible with the STM32MP2 series in the VFBGA361
10×10 mm package: the STM32MP21 uses a subset of the STM32MP23
pinout, which itself is a subset of the STM32MP25.
