[PATCH v2 0/7] ARM: Add RV1103B Omega4 board support

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@nabladev.com>

Hi,

This patch series adds support for the Onion RV1103B Omega4 board.

It covers SPL, SPI NAND boot, and the minimal board devicetree required to
boot the board.

Upstreaming the RV1103B devicetree in Linux is ongoing, but to avoid blocking
U-Boot support, this series introduces board-specific devicetrees for now.

Once the Linux RV1103B devicetrees are upstreamed, the OF_UPSTREAM mechanism
can be enabled.

In v2, the correct SoC name was used: RV1103B instead of RV1103 (Thanks Jonas!),
the RV1103B dt-bindings, devicetrees, clock and pinctrl drivers have been
submitted upstream.

The dt-bindings have already been reviewed by the Linux DT maintainer:

Tested the boot of a 6.6 OpenWRT kernel and also a 6.19-rc8 mainline kernel.

This series has successfully passed through CI.
