ARM: dts: renesas: Reserve space in 64bit R-Car DTs

2024-06-01T19:52:19+00:00

Reserve 4 kiB of space in 64bit R-Car DTs when those DTs are compiled
to permit patching in OpTee-OS /firmware node, /reserved-memory node,
possibly also additional /memory@ nodes and RPC node by TFA.

This duplicates behavior in arch/arm/dts/Makefile with OF_UPSTREAM.

dts: support building all dtb files for a specific vendor

2024-04-29T16:55:07+00:00

This adjusts OF_UPSTREAM to behave more like the kernel by allowing for
all the devicetree files for a given vendor to be compiled. This is
useful for Qualcomm in particular as most boards are supported by a
single U-Boot build just provided with a different DT.

Makefile: Add missing OF_UPSTREAM Makefile for 32bit ARM

2024-03-20T21:13:01+00:00

Copy dts/upstream/src/arm64/Makefile into dts/upstream/src/arm/Makefile
and create a commit. This makes 32bit ARM buildable with OF_UPSTREAM .

dts: Add script to uprev dts/upstream subtree

dts/update-dts-subtree.sh is just a wrapper around git subtree commands.
Usage from the top level U-Boot source tree, run:

dts: Add alternative location for upstream DTB builds

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

Allow platform owners to mirror devicetree files from devitree-rebasing
directory into dts/upstream/src/$(ARCH) (special case for arm64). Then
build then along with any *-u-boot.dtsi file present in arch/$(ARCH)/dts
directory. Also add a new Makefile for arm64.

This will help easy migration for platforms which currently are compliant
with upstream Linux kernel devicetree 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.

dts: OF_HAS_PRIOR_STAGE should depend on !BLOBLIST

2024-02-29T14:24:22+00:00

When BLOBLIST is enabled, FDT is expected to be from bloblist
carried from previous stage, instead of from OF_BOARD, therefore
only enable OF_HAS_PRIOR_STAGE when BLOBLIST is disabled.

spl: Allow enabling SPL_OF_REAL and SPL_OF_PLATDATA at the same time

2023-10-18T00:50:52+00:00

Sandbox unit tests in U-Boot proper load a test device tree to have some
devices to work with. In order to do the same in SPL, we must enable
SPL_OF_REAL. However, we already have SPL_OF_PLATDATA enabled. When
generating platdata from a devicetree, it is expected that we will not need
devicetree access functions (even though SPL_OF_CONTROL is enabled). This
expectation does not hold for sandbox, so allow user control of
SPL_OF_REAL.

There are several places in the tree where conditions involving OF_PLATDATA
or OF_REAL no longer function correctly when both of these options can be
selected at the same time. Adjust these conditions accordingly.
