Merge patch series "finish using .dtso for overlay source files"

2024-07-18T23:03:47+00:00

Rasmus Villemoes  says:

This is a followup to the patches that landed in 2024.01 and nearly
made sure that source files for producing .dtbo files use the .dtso
extension. In the same release, a few new .dts files snuck in, and
there was also some test code involving .dtbo -> .dtbo.S -> .dtbo.o I
didn't really know how to handle at the time. This should finish the
job, bring us in sync with linux (at least in this respect), and drop
the .dts -> .dtbo build rule.

kbuild: Disallow DTB overlays to built from .dts named source files

2024-07-18T19:51:07+00:00

[equivalent to linux commit 81d362732bac]

As a follow up to the series allowing DTB overlays to built from .dtso
files. Now that all overlays have been renamed, remove the ability to
build from overlays from .dts files to prevent any files with the old
name from accidental being added.

kbuild: Allow DTB overlays to built into .dtbo.S files

2024-07-18T19:51:06+00:00

[linux commit 941214a512d8, modified for U-Boot by removing the
include of vmlinux.lds.h and replacing STRUCT_ALIGNMENT by 16.]

DTB files can be built into the kernel by converting them to assembly
files then assembling them into object files. We extend this here
for DTB overlays with the .dtso extensions.

We change the start and end delimiting tag prefix to make it clear that
this data came from overlay files.

scripts/Makefile.lib: EFI: Use capsule CRT instead of ESL file

2024-07-14T07:56:24+00:00

The EFI Capsule ESL file (EFI Signature List File) used for authentication
is a binary generated from the EFI Capsule public key certificate. Instead
of including it in the source repo, automatically generate it from the
certificate file during the build process.

Currently, sandbox is the only device using this, so removed its ESL file
and set the (new) CONFIG_EFI_CAPSULE_CRT_FILE config to point to its public
key certificate.

scripts/Makefile.lib: fixes: Embed capsule public key in platform's dtb

2024-07-14T07:56:24+00:00

The call to cmd_capsule_esl_gen was made directly rather than using the
"cmd,xxx" syntax.

scripts/Makefile.lib: remove bootph-some-ram property from VPL/TPL/SPL

2024-06-26T19:17:51+00:00

The property isn't useful in VPL/SPL/TPL as it is only for U-Boot proper
pre-reloc, which has its own DTB.

Makefile.lib: find capsule ESL dtsi file with CONFIG_OF_UPSTREAM

2024-04-17T23:05:54+00:00

When CONFIG_OF_UPSTREAM is enabled, DTS files are in SOC subdirectories (vs the
top level dts directory), but when CONFIG_EFI_CAPSULE_AUTHENTICATE is enabled,
the dynamically created dtsi file containing the capsule ESL DT node is in the
parent directory. This results in a build failure because the #include inserted
in the DTS file is local to the current directory.  Update Makefile to have the
DT preprocessing of #includes search in the parent (dts top level) directory
too.

Makefile: Allow upstream DT subtree to provide DT includes

2024-03-01T03:24:05+00:00

Allow platforms to reuse DT headers and dtsi includes directly form
upstream DT subtree which will be frequently synced with Linux kernel.
This will further allow us to drop corresponding DT includes copy from
U-Boot tree.

Also, since the DT includes from upstream DT subtree are done after DT
includes from U-Boot tree, so it shouldn't cause any conflicts.

scripts/Makefile.lib: Statically define *-u-boot.dtsi files location

2024-03-01T03:24:05+00:00

Allow u-boot to build DTB from a different directory tree such that
*-u-boot.dtsi files can be included from a common location. Currently
that location is arch/$(ARCH)/dts/, so statically define that common
location.

This is needed for platform owners to start building DTB files from
devicetree-rebasing directory but still being able to include
*-u-boot.dtsi files.

Makefile: Add support for DT bindings schema checks

2024-03-01T03:24:05+00:00

This adds the build infrastructure for checking DT binding schema
documents and validating dtb files using the binding schema. Here we use
devicetree-rebasing subtree to provide the DT bindings. Along with that
adapt dts/upstream/Bindings/Makefile to align with old U-Boot Kbuild
infrastructure.

Dependency:
-----------

The DT schema project must be installed in order to validate the DT schema
binding documents and validate DTS files using the DT schema. The DT schema
project can be installed with pip::

    pip3 install dtschema

Note that 'dtschema' installation requires 'swig' and Python development
files installed first. On Debian/Ubuntu systems::

    apt install swig python3-dev

Testing:
--------

Build dts files and check using DT binding schema:
$ make dtbs_check

Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.

Note, at this point dtbs_check is an optional build target as there are
many warnings generated due to custom DT properties used by many
platforms in u-boot. It is expected with these checks that compliance
with DT bindings to take place. Once that's done it can be added to CI
builds to remain compliant with DT bindings.
