Merge patch series "*** Add Ethernet boot support for AM62Ax + phyCORE-AM62 SoMs ***"

Wadim Egorov <w.egorov@phytec.de> says:

Add general ethernet boot support for AM62Ax SoC.
Some of the work is based on TI's downstream u-boot patches found in
[1], patches touching code in mach-k3 and *.yaml board config files.

Also, provide defconfigs and device tree changes for phyCORE-AM62x and
phyCORE-AM62Ax to support booting via ethernet.
