Prepare v2026.07-rc3
babae80169d removed bootm_size from ti_common.env to allow K3 boards
to process images larger than 256MB, but preserved it in
ti_armv7_keystone2.env for ARMv7 Keystone2 boards. AM57xx (also ARMv7)
was not covered by that preservation.
Without bootm_size, env_get_bootm_size() falls back to gd->ram_size,
causing initrd_high to be computed as the top of all RAM. On ARM32
boards with more RAM than the DMA zone (e.g. AM572x IDK with 2GiB),
this places the ramdisk above 0xafe00000 (HighMem), which is not
directly accessible by the kernel after MMU setup, causing a silent
crash.
With bootm_size=0x10000000, initrd_high is constrained to
0x80000000 + 0x10000000 = 0x90000000, keeping the ramdisk in the
DMA zone and allowing the kernel to access it correctly.

This patch removes the static MDIO pinmux configuration from rmii1_pin_mux[] and instead configures the MDIO pins conditionally during board_init(). Previously, the MDIO_CLK and MDIO_DATA pins were always configured for CPSW in mux.c, which could lead to unnecessary pin ownership and conflicts in scenarios where CPSW is not used. With this change, the MDIO pins are configured only when required, ensuring that CPSW Ethernet functionality in U-Boot remains unaffected. This approach keeps Ethernet boot behavior intact and provides cleaner separation between CPSW and other Ethernet use cases.

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
+ 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)

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)

This is fine:
- Networking menu doesn't exist anymore so "#\n# Networking\n#\n" won't
be in .config anymore.
- opos6uldev, uniphier_ld4_sld8, uniphier_v7 and uniphier_v8 all have
(old) CONFIG_NET enabled, (new) CONFIG_NET will still be set but
CONFIG_NET_LEGACY also needs to be defined now to reflect the stack
choice (even if default),
- stemmy has CONFIG_NO_NET set, which means CONFIG_NET and
CONFIG_NET_LWIP are not reachable anymore hence why they don't need to
be part of .config,

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.

Some extension boards have EEPROM part numbers that do not directly match their devicetree overlay filenames. Introduce a static name_mapping table and a set_cape_overlay() helper that translates the part number and version strings read from the EEPROM into the correct overlay filename. When no entry matches, fall back to the existing behavior of constructing the overlay name as "<part_number>-<version>.dtbo" directly from the EEPROM content. Add an initial entry mapping BB-GREEN-HDMI revision 00A0 to am335x-bone-hdmi-00a0.dtbo. Signed-off-by: Kory Maincent (TI) <kory.maincent@bootlin.com>
AM62d currently shares resource management configuration files with AM62a. However, AM62a resource management needs to be modified for DMA resource sharing scheme for CPSW3G Ethernet functionality to support multi-core traffic handling. Add separate AM62d-specific resource management configuration files to decouple from the AM62a changes and maintain proper resource allocation for AM62d.

bootcmd_ti_mmc had cpsw0_qsgmii_phyinit related scripts even though this was only relevant for the j721e/j7200 SoCs. This patch instead factors out those scripts into a generic 'board_init' which is called as part of bootcmd_ti_mmc. This allows boards to more easily add custom behaviour to the ti_mmc bootflow instead of having to modify the ti_common.env file. Signed-off-by: Anshul Dalal <anshuld@ti.com>
