This patchset changes the generation of the Raspberry Pi devices DTB
files to improve the support for out-of-tree device-tree overlays, like
it has recently been done for the Nvidia SoCs.
I personally only need that for arm64, but I have added a similar patch
to do the same on arm.

Add the '-@' DTC option for the Raspberry Pi devices. This option
populates the '__symbols__' node that contains all the necessary symbols
for supporting device-tree overlays (for instance from the firmware or
the bootloader) on these devices.
The Rasbperry Pi devices are well known for their GPIO header, that
allow various "HATs" or other modules do be connected and this enables
users to create out-of-tree device-tree overlays for these modules.
Please note that this change does increase the size of the resulting DTB
by ~40%. For example, with v5.17 increase in size is as follows:
bcm2711-rpi-400.dtb 26481 -> 36830 bytes
bcm2711-rpi-4-b.dtb 26537 -> 36886 bytes

This looks good to me, Rob, does that approach work for you?

Since May 2023 this patch is integrated into the Debian kernel build
[1]. However it would be better if we could integrate it into the
kernel directly. Is there anything blocking? For me, the patch looks
fine. Similar patches for Nvidia boards also already got integrated
[2].
If there is no general objection against enabling the overlays, I plan
to send patches for the sun8i-h3 arm boards as well.
Best regards,

Since May 2023 this patch is integrated into the Debian kernel build
[1]. However it would be better if we could integrate it into the
kernel directly. Is there anything blocking? For me, the patch looks
fine. Similar patches for Nvidia boards also already got integrated
[2].
If there is no general objection against enabling the overlays, I plan
to send patches for the sun8i-h3 arm boards as well.
Best regards,

Thanks for the quick response. That was indeed a very recent change
(not yet in a release) which I missed.
Then I'll send the patches for the sun8i-h3-*pi*.dts by end of today.
