Device manufacturers frequently ship multiple boards or SKUs under a
single software package. These software packages will ship multiple
devicetree blobs and require some mechanism to pick the correct DTB for
the board the software package was deployed. Introduce a common
definition for adding board identifiers to device trees. board-id
provides a mechanism for bootloaders to select the appropriate DTB which
is vendor/OEM-agnostic.
Please extend CC list to more architectures? linux-arm-kernel, risc-v etc; since
the proposal below is not specific to ARM but any architecture is using the
devicetree.
Wouldn't devicetree@xxxxxxxxxxxxxxx will have concern folks from all the
architectures?
Please correct me.
No.
The chromium guys should get a CC on future versions of this stuff,
since they like doing wacky things with compatible strings in their
bootloader and this problem is one they also face. Doug Anderson and the
mediatek chromebook folks would be a good start.

Please CC Peter Griffin from Linaro as he helped restart this
discussion at Plumbers.

Also, for the oneplus boards:
Caleb Connolly <caleb.connolly@xxxxxxxxxx>
Thank you everyone. Amrit - please take care of above comments
when you post next revision and as suggested please add other
architecture mailing lists using the devicetree. Thank you.
Sure, will keep this in mind when sending next version. Thanks for pointing out.

Thanks,
Amrit.
