[PATCH 0/4] board: rockchip: Add Radxa ROCK 4D

[Jonas Karlman]

This series add initial support for the Raxda ROCK 4D board, running
from SPI flash, booting OS from SD-card and using Ethernet has been
tested.

It also adds a helper function to read and translate the new bootsource
ids reported by the BootROM of RK3576 to help support booting from SPI
flash.

Kconfig options for PCIe, NVMe and USB has been enabled and tested using
latest device tree from mmind/for-next, and should automatically start
working once the updated device tree finally reach dts/upstream.

This series depends on the "board: rockchip: Add ArmSoM Sige5" [1]
series for a clean apply.
