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 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.

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

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:

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.

Since the move to make NET a menuconfig and NO_NET a synonym of NET=n,
when NET is enabled, NET_LEGACY || NET_LWIP is necessarily true, so
let's simplify the various checks across the codebase.
SPL_NET_LWIP doesn't exist but SPL_NET_LEGACY is an alias for SPL_NET so
the proper symbol is still defined in SPL whenever needed.

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.

Various Qualcomm additions this cycle:
* USB superspeed support for 1 platform
* Initial support for the Milos platform and the Fairphone Gen 6

* Improved support for booting with OP-TEE on supported platforms
* Initial basic power domain support
Notably there is a generic change to the device core, missing power
domains will no longer cause a device to fail probe and instead will
just print a warning. This shouldn't affect any existing platforms.
Add a 100 ms delay after clearing the core soft reset bit to ensure
the DWC3 controller has sufficient time to complete its reset
sequence before subsequent register accesses.
Without this delay, USB initialization can fail on some Qualcomm
platforms, particularly when using super-speed capable PHYs like
the QMP USB3-DP Combo PHY on SC7280/QCM6490.

The U_BOOT_DRIVER macro creates a list of drivers used at link time, and
all entries here must be unique. This in turn means that all entries in
the code should also be unique in order to not lead to build failures
later with unexpected build combinations. Typically, the problem we have
here is when a driver is obviously based on another driver and didn't
update this particular field and so while the name field reflects
something unique the linker entry itself is not. In a few places this
provides a more suitable string name as well, however.

The upstream devicetree am33xx.dtsi does not have a "ti,am33xx-usb"

implementation of ti-musb uses a wrapper driver that binds to
ti,am33xx-usb and creates new devices ti-musb-host and
ti-musb-peripheral depending on the dr_mode property.
To avoid this wrapper driver with the upstream devicetree, add

The cdns3_bind() function is responsible for identifying the appropriate
driver to bind to the USB Controller's device-tree node. If the device-tree
node has the 'dr_mode' property set to 'otg', the existing approach fails
to bind a driver, leading to loss of functionality.
To address this, use the VBUS Valid field of the OTG Status register to
determine the role as follows:
- If VBUS Valid field is set, it indicates that a USB Host is supplying
power and the Controller should assume the Peripheral role.
- If VBUS Valid field is clear, it indicates the absence of a USB Host and
the Controller should assume the Host role.
Additionally, when 'dr_mode' happens to be 'otg' and the STRAP settings
are not specified, use VBUS Valid to determine the role in cdns3_drd_init()
and assign it to cdns->dr_mode.

(modprobe dwc3 && modprobe -r dwc3 executed 1000

When aborting a Transfer Descriptor (TD), the xHCI driver updates the
device dequeue pointer by converting the virtual enqueue TRB pointer
into a DMA address.
Previously, the code OR-ed the ring's Dequeue Cycle State (DCS) bit into
the virtual TRB pointer before passing it to xhci_trb_virt_to_dma().
This produced an unaligned virtual address (e.g. ending in 0x...1).
Inside xhci_trb_virt_to_dma(), the offset calculation:
segment_offset = trb - seg->trbs;
operated on this unaligned pointer, resulting in an incorrect TRB index.
In wraparound cases, this caused the bounds check to fail and the
function to return 0.
As a result, a SET_DEQ_PTR command was issued with a DMA address of 0x0,
leading to controller hangs and transfer timeouts, most commonly when
aborting TDs near the end of a ring segment (e.g. index 63).
Fix this by translating the aligned virtual TRB pointer to a DMA address
first, and only then applying the DCS bit to the resulting physical
address.

- mmc and i2c clock configuration fixes
- significant fixes for rpmh and regulator drivers
- added config fragment for pixel devices
- sa8775p clock fixes
- support for "flattened" dwc3 DT that recently landed upstream for
sc7280 (qcs6490) and a few other platforms
Qualcomm devicetrees are moving away from having a glue node with dwc3
as a subnode and now may just have a single flattened node.
Rockchip already have a glue_get_ctrl_dev op which returns the node for
the glue device itself, commonise this and reuse it for the new Qualcomm
node.
Lastly adjust the qscratch base address since it now requires an offset
from the dwc3 base.

The Linux support for dwc3 on Apple silicon SoCs switched to using a
apple specific glue driver [1] that uses it own compatible string. The
glue driver handles platform specific requirements on the interaction
between dwc3 and the USB2/USB3 PHY and reset-controller for USB role
switches and plug events.
To keep USB working as before when the nodes still carried "snps,dwc3"
as compatible add "apple,t8103-dwc3" to the of match table. Eventually
it is probably advisable to add a dwc3-apple glue driver and write code
for the currently empty Apple Type-C PHY driver in phy-apple-atc.c.

Added delays before and after setting the PIPE_UTMI_CLK_SEL and
PIPE3_PHYSTATUS_SW bits in the Qscratch GENERAL_CFG register
during UTMI clock selection for DWC3 on Qualcomm platforms.
These delays help ensure proper timing and stability of the UTMI
clock switching sequence, potentially avoiding race conditions or
unstable PHY behavior during initialization.
Tested on platforms using Qscratch-based DWC3 PHY configuration.
This change is taken from this Linux kernel implementation:

Tom Rini <trini@konsulko.com> says:
As seen by a number of patches fixing memory leaks, U-Boot has a problem
with developer expectations around devm_kmalloc and friends. Namely,
whereas in Linux these memory allocations will be freed automatically in
most cases, in U-Boot this is only true if DEVRES is enabled. Now,
intentionally, in xPL phases, we do not (and do not offer as an option)
enabling DEVRES. However in full U-Boot this is left either to the user,
or some drivers have select'd DEVRES on their own. This inconsistency is
a problem. This series goes and deals with two small issues that were
shown by having all drivers that use devm_.alloc to allocate memory also
select DEVRES and then we make DEVRES no longer be a prompted option and
instead select'd as needed. We do not make this unconditional as it
would result in growing the resulting binary on the many platforms which
have no users of the devm_.alloc family of functions.
Link: https://lore.kernel.org/r/20251227223833.3019311-1-trini@konsulko.com
The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

There are two places where ci_ep->desc could be accessed despite it is
not valid at that moment. Either the endpoint has not been enabled yet
or it has been disabled meanwhile (The ethernet gadged behaves this way
at least.). That results in dereferencing a null pointer.
Moreover, the patch gets rid of possible outstanding requests if the
endpoint's state changes to disabled.

Documentation [1] states that the default value of the dr_mode property
is "otg". It also isn't marked a mandatory node, so it may or may not be
set. So, accordingly if dr_mode is not mentioned in the devicetree node,
OTG mode must be assumed.
In this driver however, this case is not handled. If dr_mode is not
mentioned, USB_DR_MODE_UNKNOWN is set. The logic implemented raises an
error, instead of falling back to USB_DR_MODE_OTG. Correct this to
conform to the specification.

All instances of the U_BOOT_DRIVER must use a unique name or they will
lead to link time failures due to name space conflicts when both are
