Oops, it seems b4 messed up the subject line.
It should contain "[meta-rockchip][PATCH]"

All my patches sent by b4 have the same pattern as yours. Glancing at 
b4's code, I believe this is how it's intended to work, c.f. 
get_rebuilt_subject() in src/b4/__init__.py

Good to know. So, it's not too bad.
Thanks for your reply!

I just accepted some patches into current master that should deal with
[presubject] the way Yocto lists expect that to happen. Please try them out if
you can.

Do you mean meta-rockchip? I believe I have the latest changes and I'm 
using Quentin's .b4-config file from last year...

https://git.kernel.org/pub/scm/utils/b4/b4.git/commit/?id=d7232f5db2e4

Konstantin meant b4 added support for this in master.

I don't know if we can have send-prefixes as a fallback to 
send-presubject in .b4-config for versions of b4 that predates the 
support of send-presubject.

Essentially:
b4 < current master
    send-prefixes
b4 >= current master
    send-presubject

I (a contributor) would rather have a slightly "wrong" subject with 
combined PATCH and prefixes than having no prefix/presubject at all.

Cheers,
Quentin

Not sure the board identifier number really is synonym of generation. In 
any case, should be "3rd" I guess :)

There's also another device tree in the kernel tree for an earlier version:

rockchip/rk3566-orangepi-3b-v1.1.dtb

I think we should probably also have it in KERNEL_DEVICETREE.

Looking at the U-Boot code, the bootloader should be able to load the 
proper DTB based on some runtime detection.

In which case, the NAME part at the top should simply say Orange Pi 3B.

Otherwise looks good to me!

Cheers,
Quentin

Oops, indeed!
I just imitated the machine file for OrangePi 5 plus, which claimed it 
was 5th generation.
I'll remove this mention of a generation which is indeed dubious.

Very cool, done!
This looks like the best way to handle this.

Indeed, fixed too.

Thanks again.

A V2 is coming soon once I'm done testing.
