RZ includes different subseries, as of today: RZ/G, RZ/V and some new RZ/T run Linux. Renesas official SW package is based on the CIP Linux, even though the support of the devices is regularly upstreamed in the Linux kernel. I kind of know that the maintainers are trying to keep things consistent and usually the same kernel image works for all the supported devices, requiring just a different device tree. My idea at the moment is to add the devices that are supported in Linux 6.1. > Have you looked at the peripherials on the SoCs? Is RZ/Five identical > to RZ/Arm in that respect?

RZ/Five is basically a RZ/G2UL with a RISC-V CPU instead of Arm. Of course for RZ/Five the same kernel binary cannot work. On top of that, it's a pity that the RZ/Five started to be supported from 6.2, I'm not sure what to do with it. > If not, how about "rzarm", leaving room for future "rzfive"?

Honestly I am fine with any naming, that's why I am here asking and discussing it.
