Yep. One example is r8a7743-iwg20m.dtsi.

iWave Systems make a range of SOM modules using the RZ/G1 SoCs.
I believe there are options for some of these to use 4 GB, although 1 or 2 GB is used in the boards we've upstreamed support for.
There are also other SOM vendors (e.g. Emtrion) and end users of RZ/G1, but I'm not sure of the details.
Kind regards, Chris
