Add CMA (Contiguous Memory Allocator) reserved-memory regions to all
Xilinx arm64 board device trees to support runtime FPGA programming.
The CMA pool uses dynamic allocation constrained to the low 2 GB DDR region
via alloc-ranges so that the kernel places it within the 32-bit addressable
space.
CMA sizes are chosen per silicon family to accommodate the maximum PL
bitstream/PDI size:
- Kria K24 SOM: 64 MB
- ZynqMP boards: 128 MB
For Kria K24 SOM the CMA inherited from K26 is overridden to 64 MB.
For Kria SOMs, the CMA node is added to the SOM DTS only, not to
carrier board overlays.

patman is now maintained as a standalone 'patch-manager' package, so
remove it from the tree. The command becomes a stub that tells people to
run 'pip install patch-manager'.
buildman still imports the shared modules commit and patchstream (along
with their dependencies), so this series leaves those in place. It drops
the tool's code, tests, CI hooks and packaging, and removes the in-tree
documentation, moving the b4 contributor guide alongside the patman note
in the patch-sending docs. It also adds a .patman-defaults file so the external
tool is set up for U-Boot, next to the existing .b4-config. Where the CI
jobs relied on patman's requirements for the setuptools that pylibfdt
needs, they now install scripts/dtc/pylibfdt/requirements.txt instead.
More could be done here: commit and patchstream (and their dependencies
series, get_maintainer and settings) only remain because buildman still
imports them. A follow-up could move those into u_boot_pylib (or
buildman itself) and drop the rest, leaving tools/patman as just the
stub.

patman is now installed from the separate patch-manager package. It reads
a .patman-defaults file from the tree root as its lowest-priority config,
so a project can ship defaults that developers still override from their
own ~/.patman, a local .patman or the command line. This behaviour is new
in patman version 0.0.20
Add one for U-Boot, alongside .b4-config, pinning the patchwork server and
the get_maintainer.pl invocation so the tool works out of the box without
depending on patman's built-in defaults. A few other settings are listed,
commented out, as a starting point.

The CI runner image pre-caches pip packages by downloading each tool's

This reverts commit b42c67188c ("mmc: sdhci-cadence: trigger tuning
for SD HS mode on SD6HC (v6) PHY").
The reverted patch introduced several issues:
1. Non-standard tuning trigger: The SD Physical Layer Specification
only mandates execute_tuning for SDR50 and SDR104 UHS-I modes.
Triggering tuning for SD High Speed mode is outside the spec and
is handled via a non-standard set_ios_post callback rather than
through the established SDHCI framework tuning path.
2. Non-standard device tree property: The patch introduced a new
"cdns,sd-hs-tuning" DT property to opt into SD HS tuning. This
is not aligned with existing DT bindings and bypasses the standard
MMC capability negotiation mechanism.
3. Incorrect tunable mode allowlist: The sdhci_cdns6_mode_is_tuned()
function includes SD_HS, UHS_SDR50, and MMC_HS_400_ES as tunable
modes. According to the Cadence SD6HC IP User Guide (section 7.5.2,
Figure 18), tuning is only required for UHS-I SDR104 (SD) and
HS200 (eMMC). SD High Speed, UHS-I SDR50, and DDR50 only require
a PHY settings update from the pre-calculation script, not the
tuning procedure. HS400 transitions through HS200 and reuses its
tuned DLL value with a partial settings update. HS400ES only
requires a plain settings update from the calculation script with
no dependency on HS200 tuning.
4. Tuned state management outside the framework: The patch manually
tracks tuned DLL state (tuned_mode, tuned_dll_slave_ctrl) and
restores it across PHY reconfigurations. This duplicates
responsibility that belongs in the core MMC tuning framework and
adds unnecessary complexity to the driver.
Reverting to realign the driver with the IP documentation and the SD
Physical Layer Specification.

When a UHS card successfully negotiates 1.8V signaling during normal
initialization, the host voltage switch is performed as part of the
ACMD41 handshake. Without this fix, the warm-reboot recovery path
would fire again immediately after, switching the host voltage a
second time unnecessarily.
Add a check so the recovery path is only entered when the voltage

Move the bulk of the board environment from CFG_EXTRA_ENV_SETTINGS in
ls1028ardb.h to board/nxp/ls1028a/ls1028ardb.env. Because the board
directory is shared with ls1028aqds, the file is selected through
CONFIG_ENV_SOURCE_FILE rather than the SYS_BOARD default.
The distro_bootcmd machinery cannot be expressed in a .env file. The
BOOTENV macro expands to environment text with embedded NUL separators,
and the board overrides three distro variables (boot_scripts,
boot_a_script and scan_dev_for_boot_part) that must follow BOOTENV to
take effect. BOOTENV and those three overrides therefore remain in
CFG_EXTRA_ENV_SETTINGS, which is concatenated after the .env text, while
every other variable moves to the .env file.
The resulting default environment is functionally unchanged for both the
ls1028ardb_tfa and ls1028ardb_tfa_SECURE_BOOT defconfigs. This was
verified with an order aware comparison of the default environment before
and after the change. The only difference is that three accidental double
spaces in xspi_bootcmd, sd_bootcmd and emmc_bootcmd collapse to single
spaces, because the preprocessor normalises whitespace in the now
unquoted text, which does not affect command parsing.

- commit fcb48b8981 ("drivers: sysreset: Add sysreset op that can take

There was a conflict reverting commit 63c806ba0e ("qcom_defconfig:
enable psci based sysreset") due to commit 02ef1859b4 ("configs:
Resync with savedefconfig"), but the conflict resolution was trivial.
The args support for the sysreset uclass contains a logic bug. The first
sysreset device implementing the request_arg callback will consume the
args, not support the specified arg and thus return -EPROTONOSUPPORT
which will stop the iteration over all sysreset devices.
This is an issue if one has multiple sysreset devices and each with
support for different (valid) args. If a sysreset device implements a
-dummy argument and another -foo and a user calls reset -dummy from the
U-Boot CLI, it'll depend on which sysreset device will be attempted
first. If it is the one implementing -foo, it'll return it doesn't
support the argument with -EPROTONOSUPPORT in which case the device
implementing -dummy will never be attempted and instead we'll do a cold
reset which is very likely not what's expected from the user.
Casey suggested[1] we revert this and start from scratch again with a
different implementation instead.

For example, if the board has both NVMe (priority 4) and USB MSD devices

firmware update), USB (which may be a recovery bootdev) is never hunted
automatically, leaving the board at the U-Boot prompt (user intervention
is needed, e.g. something like 'bootflow scan usb' to hunt USB).

Commit 103b1e7ce8 ("bootm: bound-check OS index in
bootm_os_get_boot_func()") added a range check to the shared accessor so
an out-of-range OS id can no longer drive an out-of-bounds read of
boot_os[]. That accessor is reached by every image format, but only a
legacy uImage can deliver an unchecked value. bootm_find_os() takes the
raw 8-bit ih_os byte straight from image_get_os() for legacy images,
whereas the FIT path reaches the accessor only after fit_image_load()
has rejected any image whose os is not one of the supported types, and
the Android path hardcodes IH_OS_LINUX. The check can therefore never
fail for FIT, where it only adds confusion and code.
Move the test to the legacy branch of bootm_find_os(), rejecting an
out-of-range OS where the untrusted byte enters. This keeps the FIT path
clear and lets the check be compiled out when CONFIG_LEGACY_IMAGE_FORMAT
is disabled. A valid OS id that has no handler is still reported by the
existing NULL return path in bootm_run_states().
