This is the baseline support for the SIMATIC IOT2050 devices.
Changes in v2:
- rebased
- sync with upstream-accepted DT
- add boot switch
- include watchdog support
Allows to boot mainline 5.10 kernels, but not the original BSP-derived kernel we currently ship as reference. This is due to the TI sysfw ABI breakages between 2.x and 3.x. We will soon provide a transitional kernel that allows booting both firmware ABIs - as long as full upstream kernel support is work in progress.
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].
Regarding patch 4: There has been some doubts on the proposed approach, but there has been also no suggestion provided for a similarly lightweight and secure embedding method. Therefore, I'm proposing our solution once again.
There are multiple checkpatch issues with this series. Can you fix them where ever possible?

Since I just pointed out some checkpatch problems to Lokesh in his last PR, I should note that out of all of this list, I only really care about the SPDX one. There are plenty of cases where: #ifdef CONFIG_FOO ... #endif
is more readable / clear than: if (IS_ENABLED(CONFIG_FOO)) { ... }
Warnings are warning and can be ignored for good reason, errors cannot.
I've done some fixes (including the SPDX one), still need to retest. v3 will follow.
