scripts/dtc: drop yaml in DT validation

2026-04-30T18:21:47+00:00

The build issues found in dtc/yamltree were partially mitigated by a
previous commit (807bcd844a: "scripts/dtc: Fix pkg-config behavior under
sysroot"), but upstream dtc simply disabled yaml, and the same should be
done here in order to permanently avoid those issues.

Backport the change below from Linux v5.18 [1]:

ef8795f3f1c ("dt-bindings: kbuild: Use DTB files for validation")

I tested this patch with a couple Yocto builds: u-boot and u-boot-tools,
using the current master branch (rev. "c53b0708f9"), having removed
libyaml-native from u-boot-tools's dependencies.

scripts/dtc: avoid discarded qualifiers in overlay_fixup_phandle

When building with GCC 15.2 the following warning show up:

Define sep as const char *.

kbuild: Use if_changed for font and splash .incbin rules

2026-04-21T21:56:54+00:00

The generated .S files for fonts and splash screens use .incbin with the
full prerequisite path. When building with O= this bakes an absolute
path into the .S file. If the build directory is later used on a
different machine (e.g. in a container), the assembler cannot find the
source file.

Follow the existing DTB convention: rename the object targets to use
compound suffixes (.ttf.o, .bmp.o), switch the pattern rules from
direct $(call cmd,...) to FORCE + $(call if_changed,...), and register
the new suffixes with intermediate_targets so that kbuild loads their
.cmd files. This lets if_changed detect when the recorded command
(including source paths) has changed and regenerate the .S file
automatically.

The EFI rule is left unchanged since its prerequisite is a generated
file in the build directory, like the DTB and DTBO rules.

The intermediate_targets entries stay in scripts/Makefile.build rather
than moving to scripts/Makefile.lib-u-boot, because that file is
included before intermediate_targets is defined and 'targets' is ':=',
so a '$(call intermediate_targets, ...)' inside it would expand to
empty and silently drop the entries. To keep the upstream block
untouched, the U-Boot additions go in a separate 'targets +=' block
immediately below.

kbuild: Move U-Boot .incbin rules to Makefile.lib-u-boot

2026-04-21T21:56:54+00:00

The font, splash-screen and EFI .incbin wrapper rules are U-Boot
additions that do not exist in the upstream Linux kbuild. Keeping them
in scripts/Makefile.lib makes re-syncing with Linux harder than it needs
to be, as every sync must manually preserve the U-Boot additions.

Move these rules into a new scripts/Makefile.lib-u-boot and include it
from Makefile.build and Makefile.xpl, right after the existing
Makefile.lib include.

This is a pure code-move with no functional change.

Add checkkconfigsymbols.py from Linux 7.0-rc1 (unchanged since v6.2).
This tool allows to identify the usage of symbols that are not defined
in Kconfig.

kbuild: Drop phandle from diff between base DT and U-Boot augmented DT if DEVICE_TREE_DEBUG=1

2026-03-03T16:34:57+00:00

Remove the "phandle = <0x..>;" properties from the DT diff between
unpatched base DT and U-Boot augmented DT if DEVICE_TREE_DEBUG=1.
The phandle numbers are only generated by DTC, but not referenced
anywhere in the DT, because the original references are specifically
not replaced by phandle numbers when recent DTC is invoked with the
-I dts -O dts flags . The phandle number are therefore only a noise
in the diff, filter them out.

tools: sunxi-spl-image-builder: support H6/H616 NAND boot

2026-02-03T20:45:27+00:00

The H6/H616 boot ROM doesn't expect a SPL scrambled the same way as
older SoCs.
It doesn't use a specific seeds table, it expects a maximized ECC
(BCH-80), a specific BBM (FF000301) and doesn't work if empty pages are
skipped (it needs its specific BBM, even in the padding).

So, add a --soc=h6 option to support H6/616 with:
- more ECC strengths
- specific BBM
- default_scrambler_seeds[] with all values
- no empty pages skip

In Kconfig, select BCH-80 by default for SUNXI_SPL_ECC_STRENGTH to make
BROM happy.

And in scripts/Makefile.xpl, use --soc=h6 option when building for a
SUN50I_GEN_H6 SoC.

Tested on Whatsminer H616 board, booting from NAND.

As part of debugging the appended device tree failure, I inadvertently
committed some changes as I was debugging to master, and not a private
branch, and pushed them as part of the release.

This reverts commit dc2d8423b19d30472b02e02b41504226908a4291 through
