[PATCH 00/12] sc5xx: Add complete board support for all ADI SC5xx boards

[PATCH 00/12] sc5xx: Add complete board support for all ADI SC5xx boards

[Greg Malysa]

This series adds the final pieces to enable mainline U-Boot to build and
boot all Analog Devices SC5xx SoCs and supports the associated carrier
board options. At this point it should be viable for new users for these
platforms to start with the latest version of U-Boot rather than our
vendor fork, however some features (such as OSPI support and falcon
boot) remain unavailable until we are able to unify our implementations
with the mainline implementations.

Changes in v2:
- Rebased series to latest u-boot master
- Replaced SC_BOOT_MODE Kconfig with SC_BCODE
- Use Kconfig to restrict choices between EZKIT and EZLITE carriers when
  appropriate
- Separate dtsi for revD and revE of sc598 SOM. RevE is the default but
  revD is included so that any customers with older hardware can boot it
  with a single change to the .dts
- Fixed GPIO naming and polarity to use only positive names (such as
  gige-reset rather than ~gige-reset) and set the active low/high flag
  appropriately, with all code references updated to reflect logical
  values rather than voltage levels

[PATCH 01/12] mach-sc5xx: Introduce Kconfig symbols for image addresses

[Greg Malysa]

From: Utsav Agarwal <utsav.agarwal@analog.com>

Add Kconfig symbols to parameterize the SPI flash layout used in a
default-ish configuration. This adds more flexibility to the default ADI
environment, enabling customers with boards based on but not identical
to an ezkit to reuse more of the infrastructure. Furthermore it allows
for yocto (the expected default) or binman (to be introduced in this
series) to configure or use the flash layout based on a single
definition of all of the parameters when creating an image.

[PATCH 02/12] mach-sc5xx: Rename SC_BOOT_MODE

[Greg Malysa]

The symbol SC_BOOT_MODE was named incorrectly and inconsistently with
its usage. The selected boot mode is set only by hardware and cannot be
adjusted through software (apart from the use of FORCE_BMODE to instruct
the boot rom to ignore the hardware setting when loading uboot proper,
but this cannot change how SPL is loaded).

This symbol actually controlled the BCODE (easily confused with BMODE,
shorthand for boot mode), so this renames it to SC_BCODE and updates the
help text to reflect its actual usage: the BCODE is an SoC- and boot
mode-specific setting that affects how the boot rom configures QSPI or
OSPI in order to read an LDR file from the associated peripheral.

[PATCH 03/12] mach-sc5xx: Kconfig: Make EZKIT and EZLITE carriers mutually exclusive

[Greg Malysa]

Support for the SOM-CRR variants introduces library level changes that
are not modelled in the device tree. As a result they cannot both be
selected at the same time, so this updates the dependency in Kconfig to
prevent them from being enabled together.

[PATCH 04/12] mach-sc5xx: Add preliminary support for binman

[Greg Malysa]

From: Utsav Agarwal <utsav.agarwal@analog.com>

Binman is optionally supported for Analog Devices sc5xx SoCs if Yocto is
not being used to create and assemble system images. The spl LDR is
generated locally but other artifacts such as kernel FIT image and root
file system are built externally and must be supplied to binman if used.

Binman is enabled by selecting the SC5XX_USE_BINMAN config symbol and
the image structure is included in the shared sc5xx device tree.

[PATCH 05/12] docker: add Analog Devices tools to docker image

[Greg Malysa]

The boot ROM on Analog Devices ADSP-SC5xx SoCs requires code packaged
in the LDR format. Normally this is available as part of
our yocto-derived toolchain but, it is not a part of any other pre-made
toolchain anymore, so it is otherwise unavailable in the docker image
for CI. This patch adds a source build from the ADI maintained github
repository. In the future, a package available for install via apt will
be available, but currently there is no arm64 build upstream, so we must
build from source for the time being to support CI on both amd64 and
arm64 runners. The same ldr tool is used for arm and arm64 for all of
our boards with names adjusted to match the expected $(CROSS_COMPILE)
for these boards.

[PATCH 10/12] board: adi: Add support for SC598

[Greg Malysa]

This adds support for the Analog Devices SC598-SOM and configurations
for using it with both the SOMCRR-EZKIT and SOMCRR-EZLITE. This adds
dtsis for both Rev D (including older revisions) and Rev E SOMs, which
are not compatible due to BOM changes. Although no new Rev D SOMs are
produced as of 2025, many are in circulation, so the RevD dtsi is
included to facilitate use for existing customers.

Changes in v2:
- GPIO names and polarities adjusted to match logical usage
- RevE support added (default) and RevD support separated to be usable
  if someone has older hardware by changing which file is included in
  the device tree.

[PATCH 12/12] MAINTAINERS: Update ADI entries for new boards

[Greg Malysa]

This adds missing maintainers entries for the ADI SC5xx defconfigs and
for a device tree binding file that was previously missed.

Signed-off-by: Greg Malysa <malysagreg@gmail.com>

---

Changes in v2:
 - Possible files relating to ADI were identified using a shell
   command like so:
   $ find ./ | xargs grep -i --color=none "Analog Devices" 2>/dev/null | awk '{ print $1 }' | tr -d ":#" | sort | uniq > maybe_adi.txt
   This file was reviewed and entries unrelated to ADI that merely
   mentioned the company name were pruned, leaving 111 files.
   Then, maintainer information was retrieved with:
   $ cat maybe_adi.txt | xargs -L1 -t ./scripts/get_maintainer.pl --separator , -f
   and each line was reviewed to ensure it matched ARM SC5XX. This
   identified one extra file that was missed previously.

I forgot to include a link to a CI run for this series:
https://gitlab.com/gmalysa/lnxdsp-u-boot/-/pipelines/2155569443. That
version is functionally the same as these patches, but the commit
messages were updated ahead of submission today so the commit hashes
are different. For the paranoid, there's an ongoing CI run for this
exact series at
https://gitlab.com/gmalysa/lnxdsp-u-boot/-/pipelines/2164366404 but it
has not yet completed (ETA 2-3 hours) and I expect not to wake up to a
failure.

Thanks,
Greg

We need to be getting a specific branch/tag (or worst case, commit) and
using --depth=1.

Does this actually do what you want, update the PATH for the shell that
we spawn and run CI in?

I'll address this in v3, thanks. There's a release tag I can use.

It does appear to do what I want, which is allow buildman to find and
invoke the ldr tool, but as for whether it is the right way to do it,
I am unsure. If I run and attach to a container to manually go through
the steps, without the ENV line I get:

~/adi-u-boot$ tools/buildman/buildman sc598-som-ezkit-spl
Building current source for 1 boards (1 thread, 32 jobs per thread)
   aarch64:  +   sc598-som-ezkit-spl
+/bin/sh: 1: aarch64-linux-ldr: not found

and with it, I get

$ ./tools/buildman/buildman sc598-som-ezkit-spl
Building current source for 1 boards (1 thread, 32 jobs per thread)
   aarch64:  w+   sc598-som-ezkit-spl
+===================== WARNING ======================
+CONFIG_OF_EMBED is enabled. This option should only
+be used for debugging purposes. Please use
+CONFIG_OF_SEPARATE for boards in mainline.
+See doc/develop/devicetree/control.rst for more info.
+====================================================
    0    1    0 /1              sc598-som-ezkit-spl

so it is sufficient for finding aarch64-linux-ldr. The CI build also
passes, which has previously failed on the world build stage for me,
when it was unable to locate the ldr executable.

Bigger picture though, is hacking up $PATH the right way to do this?
Buildman inherits the env it runs in, so it picks up the modified PATH
and then adds the toolchain directory to PATH itself, so I could drop
symlinks into the aarch64 and armv7 folders as well and have it work,
but I thought that might be even less appropriate. ADI's packaging
(for amd64 only) currently installs it as "ldr" (no CROSS_COMPILE
prefix) into /usr/bin, which won't work for us either, because the
yocto SDK build does add CROSS_COMPILE prefixes if one were to use
that to build uboot outside of CI, and we need to somehow be
compatible with all three options, which PATH+CROSS_COMPILE achieves
for now.

So the options are probably:
1) Create local symlinks to rename the binary and hack up env/$PATH to
attach this
2) Drop symlinks into
/opt/gcc-${TCVER}-nolibc/(aarch64-linux,arm-linux-gnueabi)/bin
3) Modify buildman to be aware of ldr and have a separate
configuration section where we can round up settings
4) (Cannot be done for now) ldr tool rewrite as python
package+executable wrapper, update binman to use the library and
package in LDR format

Option 4 actually makes a lot of sense, but it is not something I can
get support for from ADI for the time being, but it would solve the
other big problem: u-boot can produce a stage 1 and stage 2 boot ldr
file for us by calling ldr with uboot artifacts only, but the stage 2
ldr is rarely useful in production and is only used for standalone
testing. It is typically repackaged in a separate yocto recipe to add
optee and tfa, or to replace u-boot proper with a kernel for falcon
boot, and being able to generate ldrs from binman would allow us to
combine the other files as well.

Thanks,
Greg

Ah, good, OK.

Thanks for the details, I think for now, option 1 is OK enough, and a
future option 4 does sound like a good idea.

[PATCH 12/12] MAINTAINERS: Update ADI entries for new boards

[Greg Malysa]

This adds missing maintainers entries for the ADI SC5xx defconfigs and
for a device tree binding file that was previously missed.

Signed-off-by: Greg Malysa <malysagreg@gmail.com>

(no changes since v2)

Changes in v2:
 - Possible files relating to ADI were identified using a shell
   command like so:
   $ find ./ | xargs grep -i --color=none "Analog Devices" 2>/dev/null | awk '{ print $1 }' | tr -d ":#" | sort | uniq > maybe_adi.txt
   This file was reviewed and entries unrelated to ADI that merely
   mentioned the company name were pruned, leaving 111 files.
   Then, maintainer information was retrieved with:
   $ cat maybe_adi.txt | xargs -L1 -t ./scripts/get_maintainer.pl --separator , -f
   and each line was reviewed to ensure it matched ARM SC5XX. This
   identified one extra file that was missed previously.
