Tom Rini b40fee4d6d Merge patch series "board: toradex: k3: Sync rm-cfg with TIFS v12.00.00 firmware"
Ernest Van Hoecke <ernestvanhoecke@gmail.com> says:

This series updates the Resource Management configuration for Toradex
K3-based boards and makes sure the TIFS-specific RM configuration is
used where applicable.

For Verdin AM62P, the tifs-rm-cfg.yaml file is refreshed with
k3-resource-partition V12.00.00 so that it stays in sync with the
existing rm-cfg.yaml update for the v11.02.09 and v12.00.00 TIFS
firmware resource reservation.

For Verdin AM62, the missing tifs-rm-cfg.yaml file is added. The file
matches the TI AM62x configuration, and rm-cfg.yaml was verified to
remain unchanged when regenerated with the same tool version.

For Aquila AM69, both rm-cfg.yaml and tifs-rm-cfg.yaml are updated to
match the resource allocation changes already present in the TI J784S4
configuration files.

Finally, the Verdin AM62 and Verdin AM62P binman descriptions are
updated to use tifs-rm-cfg.yaml for the TIFS RM fragment when building
tiboot3 images, following the same pattern used by the corresponding TI
AM62x/AM62Px platforms.

The generated/updated files were compared against the matching TI board
configuration files where applicable.

Abhash Kumar JhaandTom Rini 59d52a9975 board: ti: j722s: add processor ACL entry for wkup_r5
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.

Tom Rini 746a986fe2 Merge patch series "fit: dm-verity support"
Daniel Golle <daniel@makrotopia.org> says:

This series adds dm-verity support to U-Boot's FIT image infrastructure.
It is the first logical subset of the larger OpenWrt boot method series
posted as an RFC in February 2026 [1], extracted here for independent
review and merging.

OpenWrt's firmware model embeds a read-only squashfs or erofs root
filesystem directly inside a uImage.FIT container as a FILESYSTEM-type
loadable FIT image. At boot the kernel maps this sub-image directly from
the underlying block device via the fitblk driver (/dev/fit0, /dev/fit1,
...), the goal is that the bootloader never even copies it to RAM.

dm-verity enables the kernel to verify the integrity of those mapped
filesystems at read time, with a Merkle hash tree stored contiguously in
the same sub-image just after the data. Two kernel command-line
parameters are required:

  dm-mod.create=   -- the device-mapper target table for the verity device
  dm-mod.waitfor=  -- a comma-separated list of block devices to wait for
                      before dm-init sets up the targets (needed when fitblk
                      probes late, e.g. because it depends on NVMEM
                      calibration data)

The FIT dm-verity node schema was upstreamed into the flat-image-tree
specification [2], which this implementation tries to follow exactly.

The runtime feature is guarded behind CONFIG_FIT_VERITY. If not
enabled the resulting binary size remains unchanged. If enabled the
binary size increases by about 3kB.

Daniel GolleandTom Rini 1e48298552 tools: mkimage: add dm-verity Merkle-tree generation
When mkimage encounters a dm-verity subnode inside a component image
node it now automatically invokes veritysetup(8) with --no-superblock
to generate the Merkle hash tree, screen-scrapes the Root hash and Salt
from the tool output, and writes the computed properties back into the
FIT blob.

The user only needs to specify algorithm, data-block-size, and
hash-block-size in the ITS; mkimage fills in digest, salt,
num-data-blocks, and hash-start-block. Because --no-superblock is
used, hash-start-block equals num-data-blocks with no off-by-one.

The image data property is replaced with the expanded content (original
data followed directly by the hash tree) so that subsequent hash and
signature subnodes operate on the complete image.

fit_image_add_verification_data() is restructured into two passes:
dm-verity first (may grow data), then hashes and signatures.

from the verity metadata (block-size, data-blocks, algo, root-hash,

Also add dm-mod.waitfor=/dev/fit0[,/dev/fitN] for each dm-verity device
so the kernel waits for the underlying FIT block device to appear before
setting up device-mapper targets. This is needed when the block driver
probes late, e.g. because it depends on NVMEM calibration data.

The dm-verity target references /dev/fitN where N is the loadable's
index in the configuration -- matching the order Linux's FIT block
driver assigns block devices.  hash-start-block is read directly from

Its details belong in Kconfig help or the rST documentation.

Remove the section instead of keeping partial stale configuration
documentation in README.

James HilliardandTom Rini 5e41a5deb4 env: migrate static flags list to Kconfig
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.

Tom Rini 77efd55f89 Merge patch series "boot/fit: use fdt_for_each_subnode() in image-fit.c"
Aristo Chen <aristo.chen@canonical.com> says:

This series ends with replacing the verbose fdt_next_node() + ndepth
idiom in boot/image-fit.c with fdt_for_each_subnode(), bringing the
file in line with boot/image-fit-sig.c. Six of the seven sites in
image-fit.c predate the macro by 2-6 years; the seventh was
copy-pasted from a neighbour in 2015 just after the macro landed.
The old idiom is legacy, not a deliberate technical choice.

Converting straight to the macro turned out to need a prerequisite,
which is patch 1. fit_print_contents() reads the default-config
property using the loop variable left over after iterating /images
children. With /images defined first in the source (the conventional
layout) libfdt's walker happens to leave that variable pointing at
/configurations and the read works. With /configurations defined
first the read returns NULL and the "Default Configuration" line is
silently omitted. fdt_for_each_subnode()'s post-loop value is
unconditionally a negative error code, so a naive conversion would
have made the missing line the unconditional behaviour. Patch 1
reads the property from confs_noffset directly and removes the
layout dependency.

Patch 2 adds a regression test for the configs-before-images
layout, which had no coverage.

Patch 3 is the mechanical conversion at all seven sites,
equivalence-preserving as described in the per-patch message.

Aristo ChenandTom Rini 2c9b117aa4 boot/fit: use fdt_for_each_subnode() in image-fit.c
Replace the verbose fdt_next_node() + ndepth pattern with the
fdt_for_each_subnode() macro at all seven sites in boot/image-fit.c
where the loop only ever processes direct children. The macro is
already defined in <linux/libfdt.h> and used in boot/image-fit-sig.c,
so this brings image-fit.c in line with the rest of the FIT code.

The conversions are equivalence-preserving:

  - fit_get_subimage_count(): the depth-1 filter and the macro are
    both restricted to direct children.
  - fit_conf_print(): the parameter is named noffset, so the loop
    now uses sub_noffset to keep the parent reference stable.
  - fit_print_contents(): the count reset that lived inside the for
    initialiser is moved out as an explicit assignment before each
    loop, so the second loop still starts from zero.
  - fit_image_print(): straightforward replacement.
  - fit_all_image_verify(): same shape as the print loops, with the
    count reset moved out as an explicit assignment before the loop.
  - fit_conf_find_compat(): the body's "if (ndepth > 1) continue"
    guard is redundant once the macro is in use, and is dropped.

No behaviour changes outside of these mechanical reductions. Local
ndepth declarations that are no longer referenced are removed.

Aristo ChenandTom Rini b31f551bfc test: fit: regression test for default-config print with reversed node order
Add a test that builds a FIT whose /configurations node is defined
before /images in the source, runs iminfo, and asserts that the
"Default Configuration: '<name>'" line appears in the output.

Before the fix in the preceding commit ("boot/fit: read default-config
property from the configurations node"), fit_print_contents() read the
default-config property using the loop variable left over from iterating
/images children. With /images defined first that variable accidentally
pointed at /configurations and the line printed correctly; with
/configurations defined first the read returned NULL and the line was
silently omitted. The new test exercises the latter layout, which had
no coverage.

iminfo and the fit_print_contents() path had no test coverage at all
before this commit.

Aristo ChenandTom Rini 646be6d5cd boot/fit: read default-config property from the configurations node
In fit_print_contents() the default configuration's unit name is read by
calling fdt_getprop() with noffset rather than confs_noffset. Today this
happens to work by coincidence: the preceding loop walks /images using
fdt_next_node(), and when iteration leaves the subtree libfdt returns
the offset of the next sibling in DFS order, which by FIT layout
convention is /configurations. The depth counter then drops below zero
and the loop exits with noffset still pointing at /configurations.

This relies on /images and /configurations being adjacent siblings and
on the implementation detail of fdt_next_node()'s post-exhaustion
return value. It also blocks a follow-up conversion to
fdt_for_each_subnode(), whose post-loop loop variable is a negative
error code rather than a valid offset.

Use confs_noffset directly, which the comment immediately above the
call already names as the source.

Simon GlassandTom Rini a219f64c27 cros_ec: Sync ec_commands.h from upstream Chrome OS EC
Sync include/ec_commands.h from upstream commit 4f3d17aa34
("skywalker: set SLEEP_TIMEOUT_MS to 50 seconds"). The new file makes
two build assumptions that do not hold for U-Boot.

It hides '<stdint.h>' from __KERNEL__ builds, leaving UINT16_MAX
(used by EC_RES_MAX) undefined for U-Boot; widen the gate to
'!defined(__KERNEL__) || defined(__UBOOT__)'

It gates '<linux/limits.h>' on '#ifdef __KERNEL__'; the matching
'#else' branch defines BIT()/BIT_ULL()/GENMASK()/GENMASK_ULL()
locally, assuming kernel headers provide those macros otherwise.
U-Boot defines __KERNEL__ too but has no <linux/limits.h>. Nest a
'!defined(__UBOOT__)' check around the include so the __UBOOT__ path
stays in the __KERNEL__ branch (no local BIT/GENMASK defines), which
avoids redefinition warnings against U-Boot's linux/bitops.h. Pull
in linux/bitops.h up front for U-Boot so the file's own BIT() and
GENMASK() uses still resolve.

Adapt callers to two interface changes. The 'ec_current_image' enum
tag is now 'ec_image' (EC_IMAGE_* constants unchanged); rename it in
affected files to match. The VBNV-context interface was dropped
upstream, but it still used in lab Chromebooks; keep those constants and
structs in cros_ec.h

Likewise, MEC_EMI_BASE and MEC_EMI_SIZE are a U-Boot-local addition to
ec_commands.h that the upstream sync removes; preserve them in cros_ec.h
next to the VBNV block, and switch the only consumer
(arch/x86/cpu/apollolake/cpu_spl.c) to include cros_ec.h

If the LED is in the ON state, it is briefly set to OFF
then to ON immediately due to falling-through in the default

This commit ensures that no fall-through occurs and thus
a LED initially in the ON state is turned off before blinking.
