[PATCH 0/2] Add SIMATIC IOT2050 board support

[Jan Kiszka]

This is the baseline support for the SIMATIC IOT2050 devices.

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.

Related but not strictly needed for baseline support is [1], i.e.
embedding of the watchdog firmware that is required on the AM65x. I will
soon pick up that discussion again.

A staging tree for complete IOT2050 support can be found at [2]. Full
image integration is available via [3].
