I did think about bflb vs bouffalolab. Here is what I thought: I came
across "marvell" vs "mrvl" sevral years ago, I got an impression
"marvell" vendor prefix is preferred if I read the discussions
correctly.

As for Bouffalolab vendor prefix, I have no preference, maybe DT
maintainers can provide inputs here.
Rob, Conor, Krzysztof, what's your opinion?

Thanks
