No, I think it is the other way around.  Folk like me and Nicolas over
the last ten years have put considerable amounts of effort into trying
to keep the ARM support code as clean and maintainable as possible.

That is true of the common ARM stuff, but there's no way we can do this
for all SoC support - there aren't the hours in the day to provide such
a wide oversight.  That's why we have SoC maintainers, and the SoC
maintainers have the responsibility to sort out their own sub-trees.
