[PATCH 00/17] Renesas RZ/N1 additional drivers

Enable many more of the peripherals found on Renesas RZ/N1 SoC,
including GPIO, MMC, QSPI, NAND, Ethernet GMAC/switch/converters.

This builds on top of the basic support that was added in May 2023:
https://lists.u-boot-project.org/pipermail/u-boot/2023-May/518098.html

It has been tested on the Schneider RZ/N1 board, including support
for USB (DFU/fastboot/UMS) using the driver from Romain Gantois:
