But at Broadcom we use a slight different format for reference boards that we started from day 1: bcm9<soc>-<ref board model>.dts such as bcm963138REF.dts. And there are many in the kernel as well if you search "bcm9*.dts". Many of them are Broadcom reference boards and some are actual consumer product.

I actually was thinking to ask you if we can change all the 4908 boards to use bcm94908- prefix to be consistent with Broadcom board name convention. But at the second thought, I didn't ask because it does not make much benefit other than a uniform name, unless you agree and I can make that change. Otherwise, I would rather keep them as they are now because we have ton of reference boards here and we don't want to make that changes to remove the 9 (which will definitive cause big confusing internally) and there are no rule in linux for the name as far as I know. What I can do is update the bcmbca.yaml to put bcmbca board name rule bcm9<soc>-<ref board model>.dts for broadcom reference board and bcm<soc>-<manufacturer>-<model>.dts for customer board, if that sounds good to you.
