  Description     : Pre-built Rockchip bootloader firmware binaries (for embedded targets)

This package contains the Rockchip bootloader firmware binaries, primarily
used for targets where no open-source versions is yet released.
The pre-built firmware consists of builds of Arm Trusted Firmware, OP-TEE
and U-Boot. There are also some closed-source tools in this repo, build for
amd64. These will be stripped from the upstream source package as I do
not (yet) see a need for these.

This package is required to build U-Boot for some embedded targets such as
rk3588, rk3566, rk3568. All of these will eventually have open-source
firmware, but it is still useful for new processors in the future where
U-Boot support will be merged long before the initial DRAM bringup and
trusted firmware.

I expect this package will go into non-free-firmware.

If anyone rejects having this kind of package in Debian, please do reply
to this message. I don't have any immediate plans to package this.

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:

Not sure about the other rk35xx variants.

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. :(

Hi Vagrant  and Kever,
u-boot like other platforms?

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.

Hi Christopher,

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,

- Kever
