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.

Changes in v5: - rebase to u-boot v2023.04-1037-gb646e1f69f - many small changes in response to reviewer comments - move rzn1 into mach-rmobile (similar to existing rza1) - move board-specific DDR init to board dir
Changes in v4: - rebase to u-boot v2023.04-rc3 - remove RFC prefix - cc entire series to Marek by request - clock tables synced with linux (pending patches) - documentation and comment improvements
Changes in v3: - many tweaks to clock driver based on reviewer feedback - rebased to u-boot v2023.04-rc2 - reviewer suggestions added to spkgimage.c - many small cleanups, checkpatch, FIXMEs resolved
Changes in v2: - rewrote the stand-alone spkg_utility to integrate into mkimage
