octa-core CPU (4x Cortex-A72 + 4x Cortex-A53), Mali-G52 GPU, and a
powerful 6 TOPS NPU, making it ideal for AI and multimedia tasks.
Features tested on a Radxa ROCK 4D v1.112:

ROCK 4D boards with SPI Flash is configured to boot from FSPI0->UFS->USB,
or directly from USB when the MASKROM button is pressed, booting
directly from SD-card is not possible on these boards.

Why?
If the upstream DT is wrong, please fix the upstream DT first and
cherry-pick.
This has already been fixed in upstream DT [1], however it is targeted
for v6.17 so not pickable for another 4-6 weeks.
Maybe it'll make it in time for 6.16 but I don't see it in Heiko's
v6.16-armsoc/dtsfixes so it probably is too late in the cycle :)
Can you add a comment that this can be removed once
https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/commit/?h=v6.17-armsoc/dts64&id=cd803da7c033e376a66793a43ee98e136bc6cc25
is merged into U-Boot DT?
So this part is fine with me now, thanks for the explanation :)
Cheers,
Quentin
