This is the baseline support for the SIMATIC IOT2050 devices.
Changes in v8:
- rebased
- added support for product generation 2 board
- align device trees with upstream [pending] kernel version
- only warn on missing watchdog firmware binary
- removed bits only needed for incomplete prueth support
Changes in v7:
- rebased
- registered board doc with index
Changes in v6:
- rebased
- converted board README to docs/board/siemens/iot2050.rst
Changes in v5:
- rebased
- use DEFAULT_LINUX_BOOT_ENV from ti_armv7_common.h, rather than
home-grown values
- avoids misaligned kernel load address
- no longer exposes issue around LMB reservations
Changes in v4:
- rebased
- make rtd-wdt firmware a "loadable" inside U-Boot proper fit image,
avoiding controversial embedding as object
- improved mmc1 removal from boot_targets
- fixed various build issues
Changes in v3:
- rebased
- addressed several checkpatch warnings
- a few #ifdef -> IS_ENABLED conversions
- comment marker for SPDK identifier in .S file
- trailing whitespaces
- factored out rti_wdt_load_fw (less #ifdef)
Changes in v2:
- rebased
- sync with upstream-accepted DT
- add boot switch
- include watchdog support
Allows to boot mainline kernels and the BSP-derived kernel we currently
ship as reference.
Note that this baseline support lacks Ethernet drivers. We are working
closely with TI to ensure that the to-be-upstreamed icssg-prueth driver
will work both with new SR2.0 AM65x silicon as well as with SR1.0 which
is used in the currently shipped IOT2050 devices.
A staging tree for complete IOT2050 support can be found at [1]. Full
image integration is available via [2].

Prepares for the addition of the IOT2050 board which is based on the TI
AM65x. The board comes in four variants, Basic and Advanced, each as
product generation 1 (SR1.0) and 2 (SR2.x), so there are separate dts
files needed. Furthermore, the SPL has its own device tree.
Based on original board support by Le Jin, Gao Nian and Chao Zeng.

From: Jan Kiszka <jan.kiszka@siemens.com>
This adds support for the IOT2050 Basic and Advanced devices. The Basic
used the dual-core AM6528 GP processor, the Advanced one the AM6548 HS
quad-core version.
Both variants are booted via a Siemens-provided FSBL that runs on the R5
cores. Consequently, U-Boot support is targeting the A53 cores. U-Boot
SPL, ATF and TEE have to reside in SPI flash.
Full integration into a bootable image can be found on
https://github.com/siemens/meta-iot2050
Based on original board support by Le Jin, Gao Nian and Chao Zeng.

+SIMATIC IOT2050 BASIC and ADVANCED
+==================================
+
+The SIMATIC IOT2050 is an open industrial IoT gateway that is using the TI
+AM6528 GP (Basic variant) or the AM6548 HS (Advanced variant). The Advanced
+variant is prepared for secure boot.
+
+The IOT2050 starts only from OSPI. It loads a Siemens-provided bootloader
+called SE-Boot for the MCU domain (R5F cores), then hands over to ATF and
+OP-TEE, before booting U-Boot on the A53 cores. This describes how to build all
+open artifacts into a flashable image for the OSPI flash. The flash image will
+work on both variants.
+
+Dependencies
+------------
+
+ATF: Upstream release 2.4 or newer
+OP-TEE: Upstream release 3.10.0 or newer
+
+Binary dependencies can be found in
+https://github.com/siemens/meta-iot2050/tree/master/recipes-bsp/u-boot/files/prebuild.
+The following binaries from that source need to be present in the build folder:
+
+ - tiboot3.bin
+ - sysfw.itb
+ - sysfw.itb_HS
+ - sysfw_sr2.itb
+ - sysfw_sr2.itb_HS
+

Add the DT entry for a watchdog based on RTI1. It requires additional
firmware on the MCU R5F cores to handle the expiry, e.g.
https://github.com/siemens/k3-rti-wdt. As this firmware will also lock
the power domain to protect it against premature shutdown, mark it
shared.
Aligns us to the kernel's DT in this regard.

To avoid the need of extra boot scripting on AM65x for loading a
watchdog firmware, add the required rproc init and loading logic for the
first R5F core to the watchdog start handler. In case the R5F cluster is
in lock-step mode, also initialize the second core. The firmware itself
is embedded into U-Boot binary to ease access to it and ensure it is
properly hashed in case of secure boot.
One possible firmware source is https://github.com/siemens/k3-rti-wdt.
The board is responsible for providing the firmware as additional
loadable via the U-Boot fit image. The driver will pick up its location
from /fit-images/k3-rti-wdt-firmware then.

This allows to use the watchdog in custom scripts but does not enforce
that the OS has to support it as well.

So, in applying
https://patchwork.ozlabs.org/project/uboot/patch/20210910213743.30793-1-trini@konsulko.com/
to bring us fully to v5.14 for K3 platforms, this patch is no longer
needed, and I'm deferring it. The only difference is the node name is
"watchdog@40610000" not "rti@40610000" but should not matter (and
doesn't look to from a quick read of the rest of the series.
