[PATCH 00/11] ARM: rockchip: Add initial RV1103B and Omega4 board support

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@nabladev.com>

This series adds initial support for the Rockchip RV1103B SoC and
the Omega4 board.

The goal of this series is to provide the minimal device tree and
platform support required to boot the Omega4 board into Linux
userspace with the root filesystem located on SPI NAND.

The series includes:

  - Base RV1103B SoC device tree description
  - Omega4 board device tree
  - Required pinctrl and clock definitions
  - Basic peripheral enablement required for boot

With this series applied, the Omega4 board is able to:

  - Initialize DRAM
  - Boot the kernel
  - Access SPI NAND
  - Mount the root filesystem from SPI NAND
  - Reach userspace successfully

This submission intentionally focuses on minimal bring-up support.
Additional peripheral enablement and feature support will be
submitted separately.

Tested on Omega4 hardware based on the RV1103B SoC.

Boot verified with root filesystem stored on SPI NAND.
