This is a friendly reminder during the review process.
It seems my or other reviewer's previous comments were not fully
addressed. Maybe the feedback got lost between the quotes, maybe you
just forgot to apply it. Please go back to the previous discussion and
either implement all requested changes or keep discussing them.
Thank you.
Best regards,
Krzysztof

Apologies, you are right. Now with the threading fixed, I'll be able to gather all the feedback properly.
I'll fix this on V4.

Adds support for the Blaize CB2 development board based on
BLZP1600 SoC. This consists of a Carrier-Board-2 and a SoM.
The blaize-blzp1600.dtsi is the common part for the SoC,
blaize-blzp1600-som.dtsi is the common part for the SoM and
blaize-blzp1600-cb2.dts is the board specific file.

This does not cause dtbs_check W=1 warnings? Surprising a bit... This
should cause big fat warning, so I have doubts patchset was tested.

No it doesn't cause any warnings. I did:
make arch=arm64 dt_binding_check
make arch=arm64 dtbs_check W=1
I don't get any warnings. Could you please let me know what kind of
warning I should get? Am I doing something wrong and I don't get
the warning?
Kind regards,
Niko

I was expecting one for missing soc unit address, but you are right -
your ranges are empty, so "soc" is ok. I keep forgetting that
distinction. Looks fine then.

Memory starting at 4K. That's odd. I suspect you have something
reserved there and memory really starts at 0? If so, it is preferred
that you describe memory including that 4KB and then reserve it in
/memreserve/ section or /reserved-memory node.

Ah, there it is. This isn't mmio-sram.

Just put this node into /reserved-memory.

It is preferred if you limit this to actual ranges needed. Looks like
nothing below 0x200000000, but I imagine this is incomplete.

I dunno if you've yet had any comment from Arnd on this series, but I'd
expect that the blaize patches follow the same path via the soc tree as
any other platform. I presume either you or one of the other Blaize guys
on this patchset will be taking care of that, so it would be a good idea
to add a MAINTAINERs entry covering the new arch/arm64/boot/dts/blaize
directory. There should be some more info about some of the expectations
