Add a fixed-partitions node to the NOR flash of the phyCORE-AM62x
and phyCORE-AM64x to enable the bootloader to fixup the partitions
during boot.

Why can't your bootloader add these nodes?

Hi Andrew,
We are adding the nodes directly to the device tree to match what is
done in other device trees, for example: k3-am642-tqma64xxl.dtsi. You
are correct that this could be done by the bootloader instead though.
Why do you prefer having the bootloader add the nodes?
Regards,
Nathan

k3-am642-tqma64xxl.dtsi should be fixed, it slipped past me and
shouldn't be used as a reference.
The bootloader might not fill it out at all, what if we start
using the new MTD GPT partitions? Then the new bootloaders
will have to start *removing* these stale half-nodes.
If the bootloader is going to add fixed partitions it should do
the whole job. There is no good reason to have a half complete
nodes here.
