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. 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 RZN1 board, which is fairly similar to the Renesas RZ/N1D-DB Demo board.
