That's what I said. You and Nicholas wont scale.

But the current SoC maintainer model does not work either. The SoC
maintainers care about their sandbox and have exactly zero incentive
to look at the overall picture, e.g reuse of code for the same IP
blocks, better abstraction mechanisms etc. 

Therefor you need a team of experienced kernel developers which are
NOT associated with a particular vendor who are able to tame that SoC
crowd and work closely with you and Nicholas to keep stuff in sync.
