[PATCH 00/11] boards: siemens: iot2050: SM variant, sysinfo support, fixes & cleanups

[Jan Kiszka]

This series depends on:
https://patchwork.ozlabs.org/project/uboot/patch/a54b501a-9a98-426c-a5ca-faf547411a30@siemens.com/

This adds support for the new IOT2050 SM variant, introduces a sysinfo
driver which also permits SMBIOS support and switches the board to
OF_UPSTREAM. There are some further fixes for the boards included as well.

Not yet included is configuration support for DMA isolation via the PVU as
this depends on not yet merged DT bindings and another overlay.

Not a merge-dependency but still needed to restore full support for the
IOT2050:

[Jan Kiszka]

From: Baocheng Su <baocheng.su@siemens.com>

The power control pin of pcie interface not only works for M.2 interface
but also for miniPCIE, so promote this logic to all variants to
workaround the module hang issue.

[PATCH 04/11] board: siemens: iot2050: Pass DDR size from FSBL

[Jan Kiszka]

From: Baocheng Su <baocheng.su@siemens.com>

Due to new DDR size introduction, the current logic of determining the
DDR size is not able to get the correct size.

Instead, the DDR size is determined by the FSBL(SEBOOT) then passed to
u-boot through the scratchpad info.

The SEBoot version must be >= D/V01.04.01.02 to support this change.

Also now for some variants, the DDR size may > 2GB, so borrow some code
from the TI evm to iot2050 to support more than 2GB DDR.

[PATCH 05/11] board: siemens: iot2050: Generalize the fdt fixup

[Jan Kiszka]

From: Baocheng Su <baocheng.su@siemens.com>

The fdt fixup logic actually also applies to other possible variants who
also have device tree overlays. So generalize this part by extracting
it from the m.2 specific function and make it a standalone one.

Since now we only have M.2 variant consuming the overlay, it may not
have immediate effect for other variant, however this makes the future
variant more easier to apply fdt fixups.

[PATCH 06/11] board: siemens: iot2050: Stop using special spl DT sources

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

We can simply use the default DT, Basic PG1, because no nodes that are
different between the variants play a role for SPL. Will help with the
migration to OF_UPSTREAM.

[PATCH 07/11] board: siemens: iot2050: Migrate to OF_UPSTREAM

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

This requires some tweaking of the defconfig and
board_fit_config_name_match so that the new sources are taken into
account.

[PATCH 08/11] dts: iot2050: Support new IOT2050-SM variant

[Jan Kiszka]

From: Baocheng Su <baocheng.su@siemens.com>

the dts file for IOT2050-SM variant is copied from kernel side without
any change.

Main differences between the new variant and Advanced PG2:

1. Arduino interface is removed. Instead, an new ASIC is added for
   communicating with PLC 1200 signal modules.
2. USB 3.0 type A connector is removed, only USB 2.0 type A connector is
   avaiable.
3. DP interface is tailored down. Instead, to communicate with the
   PLC 1200 signal modules, a USB 3.0 type B connector is added but the
   signal is not USB.
4. DDR size is increased to 4 GB.
5. Two sensors are added, one tilt sensor and one light sensor.

[PATCH 09/11] smbios: Fill UUID from sysinfo when available

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

Allow for the sysinfo drivers to provide a system UUID to SMBIOS. Will
be first used by the IOT2050 boards.

Based on original patch by Li Hua Qian.

[PATCH 10/11] sysinfo: Add driver for IOT2050 boards

[Jan Kiszka]

From: Li Hua Qian <huaqian.li@siemens.com>

This brings a sysinfo driver and DT entry for the IOT2050 board series.
It translates the board information passed from SE-Boot to SPL into
values that can be retrieved via the sysinfo API. Will is already used
to fill the SMBIOS table when booting via EFI.

This currently fails to build on iot2050 on master, can you please
rebase and re-run CI? Thanks.

You need to update dts/upstream to recent 6.12-rcX. I thought that
already happened long ago, but I might have confused 6.11 and 6.12, thus
did not mention this dependency for switching to OF_UPSTREAM.

Ah yes, we're on v6.11 and won't hit v6.12 for our v2025.01, so please
use the cherry-pick option outlined in
https://docs.u-boot.org/en/latest/develop/devicetree/control.html#resyncing-with-devicetree-rebasing
to bring the required changes along for now, thanks.
