arm: init: export prev_bl_fdt_addr

When booting U-Boot on board with a locked down first-stage bootloader,
we emulate the Linux boot header. By passing the U-Boot FDT through this
first-stage bootloader and retrieving it afterwards we can pre-populate
the memory nodes and other info like the KASLR address.

Add a function to export the FDT addr so that boards can use it over the
built-in FDT.

Don't check is_addr_accessible() here because we might not yet have a
valid mem_map if it's going to be populated from the FDT, let the board
do their own validation instead.

Merge patch series "An effort to bring DT bindings compliance within U-Boot"

Sumit Garg <sumit.garg@linaro.org> says:

Prerequisite
------------

This patch series requires devicetree-rebasing git repo to be added as a
subtree to the main U-Boot repo via:

$ git subtree add --prefix dts/upstream \
      https://git.kernel.org/pub/scm/linux/kernel/git/devicetree/devicetree-rebasing.git \
      v6.7-dts --squash

Background
----------

This effort started while I was reviewing patch series corresponding to
Qcom platforms [1] which was about to import modified devicetree source
files from Linux kernel. I suppose keeping devicetree files sync with
Linux kernel without any DT bindings schema validation has been a pain
for U-Boot SoC/platform maintainers. There has been past discussions
about a single DT repo but that hasn't come up and Linux kernel remained
the place where DT source files as well as bindings are placed and
maintained.

However, Linux kernel DT maintainers proposed [2] for U-Boot to rather
use devicetree-rebasing repo [3] which is a forked copy from Linux
kernel for DT source files as well as bindings. It is tagged at every
Linux kernel major release or intermideate release candidates. So here I
have tried to reuse that to bring DT bingings compliance as well as a
standard way to maintain a regular sync of DT source files with Linux
kernel.

In order to maintain devicetree files sync, U-Boot will maintains a Git
subtree for devicetee-rebasing repo as `dts/upstream` sub-directory.
U-Boot will regularly sync `dts/upstream/` subtree whenever the next window
opens with the next available kernel major release.
`dts/update-dts-subtree.sh` script provides a wrapper around git subtree
pull command, usage from the top level U-Boot source tree, run:

$ ./dts/update-dts-subtree.sh pull <devicetree-rebasing-release-tag>

If required it is also possible to cherry-pick fixes from
devicetree-rebasing tree prior to next sync, usage:

$ ./dts/update-dts-subtree.sh pick <devicetree-rebasing-commit-id>

The RFC/prototype for this series has been discussed with Linux DT
maintainers as well as U-Boot maintainers here [4]. Now we would like to
reach out to wider U-Boot community to seek feedback.

[4] https://github.com/u-boot/u-boot/pull/451

Changes
-------

Traditionally, U-Boot placed copies of devicetree source files from Linux
kernel into `arch/<arch>/dts/<name>.dts` which can be selected via setting
"<name>" when prompted for `DEFAULT_DEVICE_TREE` by Kconfig.

SoC/board maintainers are encouraged to migrate to use synced copies from
`dts/upstream/src/<arch>/<vendor>`. To do that enable `OF_UPSTREAM` for the
SoC being used via Kconfig and set up "<vendor>/<name>" when prompted for
`DEFAULT_DEVICE_TREE` by Kconfig.

An example have been shown for Amlogic meson-gxbb SoC and corresponding
derived boards via patch #10 and #11.

Devicetree bindings schema checks
---------------------------------

With devicetee-rebasing Git subtree, the devicetree bindings are also
regularly synced with Linux kernel as `dts/upstream/Bindings/`
sub-directory. This allows U-Boot to run devicetree bindings schema checks
which will bring compliance to U-Boot core/drivers regarding usage of
devicetree.

Dependencies
------------

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

Several executables (dt-doc-validate, dt-mk-schema, dt-validate) will be
installed. Ensure they are in your PATH (~/.local/bin by default).

Recommended is also to install yamllint (used by dtschema when present).

$ apt install yamllint

Running checks
--------------

In order to perform validation of DTB files, use the ``dtbs_check`` target:

$ make dtbs_check

It is also possible to run checks with a subset of matching schema files by
setting the ``DT_SCHEMA_FILES`` variable to 1 or more specific schema files
or patterns (partial match of a fixed string). Each file or pattern should
be separated by ':'.

$ make dtbs_check DT_SCHEMA_FILES=trivial-devices.yaml:rtc.yaml
$ make dtbs_check DT_SCHEMA_FILES=/gpio/
$ make dtbs_check DT_SCHEMA_FILES=trivial-devices.yaml

Makefile: Add support for DT bindings schema checks

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

100ms timeout is defined to ensure that the system doesn't lock up in
the case of an error.

Since we need to dynamically determine if we're waiting for a 0 bit or a
1 bit, it's easier to use wait_for_bit_32() than readl_poll_timeout().

This change is needed for reliable initialization of the I2C driver
which is added in a following patch.

efi_loader: set IMAGE_DLLCHARACTERISTICS_NX_COMPAT

The IMAGE_DLLCHARACTERISTICS_NX_COMPAT flag marks an EFI binary where
the following conditions are met [1]:

* Executable and writable sections are separated.
* The application does not run self-modifying code.
* The application uses the EFI_MEMORY_ATTRIBUTE_PROTOCOL when loading
  executable code.
* The application does not assume that all memory ranges are usable.
* The stack is not expected to be executable.

The only EFI binaries U-Boot provides that do not fulfill these
requirements are the EFI app and the EFI payload.

Once we have implemented separation of writable and executable memory in
U-Boot we can use the IMAGE_DLLCHARACTERISTICS_NX_COMPAT flag to decide
if we will load an EFI binary.

Merge patch series "board/ti: k3 boards: Stop using findfdt"

Nishanth Menon <nm@ti.com> says:

This is a wide cleanup to switch to setting fdtfile using env_set
instead of scripted magic. 'fdtfile' is expected to be set by default.
This allows the stdboot triggered efi loaders to find the correct OS
device tree file even if regular boot process is interrupted by user
intervention.

We shouldn't need finfdt anymore. Drop the env script.
