[RFC PATCH v1 0/9] Renesas RZ/N1 SoC initial support

[Ralph Siemsen]

The RZ/N1 is a family of SoC devices from Renesas [1], featuring ARM
Cortex-A7 and/or Cortex-M3 CPU, industrial ethernet protocols,
integrated Ethernet switch, and numerous peripherals.

This is a first step in upstreaming support for the RZ/N1 family.
Currently it contains just enough to boot to the u-boot prompt.
Additional patches will follow to support flash, SD, USB, Ethernet, etc.

At this point, I am looking for general feedback about the overall
direction and structure. I'm aware of several checkpatch warnings, and
some TODO/FIXME items, which will be addressed.

This work is based on a vendor-supplied u-boot 2017.01 tree [2],
which supports several eval boards, none of which I have access to.
Instead development has been done on a Schneider LCES2 board, which
is fairly similar to the Renesas RZ/N1D-DB Demo board.

The patches are currently against v2022.10-rc2.
