Currently, the bi_dram[] information is stored in the board info
structure (bd). Because bd is only valid after reserve_board(),
dram_init_banksize() must be called late in the initialization process.
This limitation is problematic, as it forces us to rely on a variety of
bespoke functions to determine board RAM, bank memory sizes, and other
early setup requirements.
By moving bi_dram[] into the global data (gd), we can run it earlier.
This is particularly convenient since boards define their own
dram_init_banksize() routines, which do not always rely on parsing
Device Tree (DT) memory nodes.
Additionally, U-Boot defaults to relocating to the top of the first memory
bank. While boards currently use custom functions to override this
behavior, having the DRAM bank information available earlier in gd makes
relocating to a different bank trivial and standardizes the process.

The CPSW3G instance of CPSW on AM62AX SoC provides Ethernet functionality.
Currently, Ethernet is supported on Linux which runs on the A53 core on the
SoC, by allocating all of the DMA resources associated with CPSW to A53_2.
In order to enable use-cases where the Ethernet traffic is sent from or
consumed by various CPU cores on the SoC simultaneously, while at the
same time, maintaining backward compatibility with the existing use-case
of A53 being the sole entity that exchanges traffic with CPSW via DMA,
update the DMA resource sharing scheme on AM62AX SoC to the following:
--------------- -------------- ------------- ----------------
Resource WKUP_R5 MCU_R5 A53_2
--------------- -------------- ------------- ----------------
TX Channels [8] => 4 (Primary) 4 (Primary) 8 (Secondary)
TX Rings [64] => 32 (Primary) 32 (Primary) 64 (Secondary)
RX Channels [1] => 1 (Primary) 0 1 (Secondary)
RX Flows [16] => 6 (Primary) 10 (Primary) 16 (Secondary)
In the absence of primary owners of resources (existing use-case
where A53 owns all of the CPSW DMA resources), the secondary owner
can claim all of the resources as its own. For shared use-cases,
the resources that are not claimed by the primary are communicated
to the secondary owner allowing it to claim them. This ensures that
Linux on A53_2 can continue claiming all DMA resources associated
with CPSW in the absence of primary owners, while at the same time
providing users the flexibility to share CPSW DMA resources across
various CPU cores listed above if needed.
While Linux has been mentioned as the Operating System running
on A53, there is no dependency between the Operating System
running on A53 and its ability to claim the CPSW DMA resources
listed above.

On the j722s platform, the DM firmware resets the wkup_r5 core at boot to
enable both of its TCM memories.
This reset sequence involves three steps:
- Acquiring processor ownership of wkup_r5
- Configuring the core and requesting a reset via TIFS
- Releasing ownership.
When the Linux remoteproc driver comes up, it acquires ownership of wkup_r5
to query its state, making A53_2 the new owner.
During system suspend, TIFS saves the processor ACL[1] table to DDR as
part of its context.
On resume, TIFS restores the ACL table, leaving A53_2 as the owner of
wkup_r5. At this point, DM (WKUP_0_R5_0 host[2]) no longer has ownership
and is therefore unable to perform the reset sequence it needs,
causing it to crash.
To fix this, configure the wkup_r5[3] processor with dual ownership:
- WKUP_0_R5_0 (Secure) as primary owner.
- A53_2 (Non-Secure) as secondary owner.

Some minor fixes to K3's env to avoid using hardcoded addresses but
instead move to Kconfig symbols.
Link: https://lore.kernel.org/r/[email protected]

The load addresses for DFU download binaries were hardcoded for K3
devices which required redefinition of such env for boards that deviated
from the expected K3 memory map (such as AM6254atl EMV).
This patch replaces the hardcoded addresses with their corresponding

In the TI's K3 bootflow of tiboot3.bin -> tispl.bin -> u-boot.img:
(R5 SPL) (A53 SPL)
We currently provide a common dfu_alt_info_ram for both R5 SPL and A53
SPL which is not intuitive in a regular bootflow where each binary
should only request it's immediate next stage.
This patch updates dfu_alt_info_ram such that the R5 SPL would only
request for tispl.bin and A53 SPL would only request u-boot.img.

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.

AM335_ICE
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.

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

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

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.

This series updates the Resource Management (RM) configuration files
for AM62 family devices to align with the TIFS v11.02.09 firmware.
Background
----------
With the latest TIFS firmware (v11.02.09), an additional virtual
interrupt and event is reserved for MCU cores to DM usage on am62x,
am62ax, and am62px devices. This series brings the rm-cfg and
tifs-rm-cfg files in sync with these firmware changes across both
TI reference boards and vendor boards.
These changes are backward compatible with older TIFS firmware versions.
Additionally, the am62x platform was originally introduced without a
tifs-rm-cfg.yaml file, unlike other platforms in the AM62 family.
This series addresses that gap and enables tifs-rm-cfg in binman for
am625-sk and am62p-sk platforms.
Changes
-------
TI reference boards (patches 1-4):
- Update rm-cfg.yaml for am62x, am62ax, am62px
- Sync am62px tifs-rm-cfg.yaml with TIFS firmware template
- Add missing tifs-rm-cfg.yaml for am62x
- Enable tifs-rm-cfg in binman for am625-sk and am62p-sk
Vendor boards (patches 5-9):
- beagleplay (am62x-based)
- phytec phycore_am62x
- toradex verdin-am62
- phytec phycore_am62ax
- toradex verdin-am62p
with the required interrupt reservation. The tifs-rm-cfg.yaml files
cannot be updated without access to the corresponding SysConfig files,
as both rm-cfg.yaml and tifs-rm-cfg.yaml must remain in sync.

Since commit 27cc5951c862 ("include: env: ti: add default for

do_main_cpsw0_qsgmii_phyinit happened to remain '0' and couldn't be

cyclic dependency:
A) ti_common.env sets do_main_cpsw0_qsgmii_phyinit to '0' and its value
can only be updated automatically by main_cpsw0_qsgmii_phyinit.
B) main_cpsw0_qsgmii_phyinit is defined in j721e.env and it can run only
if 'do_main_cpsw0_qsgmii_phyinit' is already '1' which isn't possible
unless the user manually assigns the value.

This series adds EEPROM board detection support for AM62x and refactors
the board detection code across AM6x family boards to eliminate code
duplication.
The series introduces two new generic functions for AM6x boards:
- do_board_detect_am6(): Reads the on-board EEPROM with fallback logic
to alternate I2C addresses
- setup_serial_am6(): Sets up the serial number environment variable
from EEPROM data

TI's AM6254atl (or AM62x SiP for short) provides the existing AM62x SoC
with 512MiB of DDR integrated in a single package.
This patch adds the necessary U-Boot devie tree files, the required
defconfigs along with the documentation for the AM62x SiP EVM.
AM62x SiP differs from the already supported AM62x in following ways:
- OP-TEE for the AM62x resides from 0x9e800000 to 0xa0000000 which needs
to be moved to 0x80080000 to free up space at end of DDR in AM62x SiP
with 512MiB of memory. This is required to allow U-Boot to relocate to
end of DDR before booting to the kernel.
- Changes to the env:
1. splashimage address updated from 0x80200000 to 0x81a00000
2. DFU addresses updated to match updated TEXT_BASE for SPL and U-Boot

Replace the board-specific implementation of do_board_detect()
with a call to the generic do_board_detect_am6() function to
avoid code duplication across AM6x family boards.
The generic function provides the same functionality with
additional fallback logic to try alternate EEPROM addresses.

I2C EEPROM data contains the board name and its revision.
Add support for:
- Reading EEPROM data and store a copy at end of SRAM
- Updating env variable with relevant board info
- Printing board info during boot
Use the generic do_board_detect_am6() and setup_serial_am6()
functions to avoid code duplication across AM6x family boards.

Add two new generic functions for AM6x family boards to simplify
board-specific implementations:
- do_board_detect_am6(): Generic board detection function that reads
the on-board EEPROM. It first attempts to read at the configured
address, and if that fails, tries the alternate address
(CONFIG_EEPROM_CHIP_ADDRESS + 1). This provides a common
implementation that can be used across different AM6x boards.
- setup_serial_am6(): Sets up the serial number environment variable
from the EEPROM data. The serial number is converted from
hexadecimal string format to a 16-character hexadecimal
representation and stored in the "serial#" environment variable.
Both functions are protected by CONFIG_IS_ENABLED(TI_I2C_BOARD_DETECT)
and are designed to be used by AM62x, AM64x, AM65x, and other AM6x
family boards.

to boot flows"
Kory Maincent (TI.com) <[email protected]> says:
This series converts the extension board framework to use UCLASS as
requested by Simon Glass, then adds extension support to pxe_utils
and bootmeth_efi (not tested) to enable extension boards devicetree load
in the standard boot process.
I can't test the imx8 extension scan enabled by the
imx8mm-cl-iot-gate_defconfig as I don't have this board.
I also can't test the efi bootmeth change as I don't have such board.

Remove the legacy extension board implementation now that all boards
have been converted to use the new UCLASS-based framework. This
eliminates lines of legacy code while preserving functionality
through the modern driver model approach.
Update the bootstd tests, due to the removal of extension hunter.
