[PATCH v5 00/10] 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.

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
