Same here :-)

Renesas offers different architectures in their portfolio[1], I haven't
dug into the OpenWRT build system for this issue yet to tell whether it
is able to handle that at this folder level. Much of the above is
"legacy" and does not run OpenWRT(?), but they also seem to aim for
Risc-V. There is a platform called "ramips" and the broadcoms each have
their own subdirectory. None of them have punctuation yet. Maybe call it
"renesasrz"? They're also offering other ARM-based SoCs, and building
common kernels might become difficult.
