[PATCH v3 00/10] 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 is now
working with the picked DT commits from the v6.17-rc1-dts tag.

Changes in v3:
- Implement read_brom_bootsource_id() for RK3528
- Add a short code comment about the re-mapping of bootsource id
- Add fspi1m1 pinctrl bootph- props to SoC u-boot.dtsi
- Drop the incomplete support for FSPI1_M0
- Pick related DT changes that now have landed in v6.17-rc1-dts tag
- Drop the now unneeded reset-gpios prop rename workaround
- Rebase on top of u-boot-rockchip-20250831 tag

Change in v2:
- Add comment about the reset-gpios prop rename in board u-boot.dtsi
