Arm Trusted Firmware for some of these rk35xx variants is now supported
in the Debian packaging and upstream. I think the only thing left for
rk3588 is the DDR training binaries from rkbin:
https://www.collabora.com/news-and-blog/blog/2024/02/21/almost-a-fully-open-source-boot-chain-for-rockchips-rk3588/
Not sure about the other rk35xx variants.
@Kever I wonder if rockchip plan to open source the RAM training into u-boot like other platforms?
I have check internally for this topic, there is no plan for open source the ddr init binary recently for rk35xx SoCs.
Rockchip already provide the source based ddrbin_tool to modify the ddr binary with all the possible
parameter which may need by customers.
So it would be better for the rkbin can merge into the Debian
non-free-firmware package.
Thanks,

This would remove need for rbkin in Debian.
PS: I don't have time to look at packaging robin until the late summer. If someone else wishes to do it, I'd happily help with reviewing and sponsor an upload into Debian.

I *think* this license looks plausible for non-free-firmware:

Those exclusions might make it hard for folks to come up with free
implementations, though. :(
live well,
