As RZ/G2UL is pin-compatible with RZ/G2LC, I guess you could have an
RZ/G2UL-based HummingBoard IIoT, too?

Is there any special meaning of the "sr" in the middle of this and all
other SoM compatible values?
If it just means "SolidRun", I think it can be dropped.  However,
you already have that for various SoMs with non-Renesas SoCs.

The rest LGTM, so
