Anyway, that's the convention or consensus so far for entire SoC. If we
want to change it - sure, but let's make it for everyone, not for just
this one USB driver.

Great, let's change it for everyone, I don't see a need for ARCH_*
symbols except for people who want to make it simpler for their one
board type.  And for that, use a defconfig.

I don't think that will work in practice. Many ARCH_ symbols for various
architectures contradict with each other. Almost all watchdog drivers
only _build_ for specific platforms/architectures.

Great, that's horrible to hear, so much for a "generic arm64 kernel
binary" which I _thought_ was the goal.

ugh, you would have thought we would have learned our lesson with
arm32...

I think Guenter here refers to drivers which actually came from arm32 
and were not cleaned up to be build without machine-specific bits 
(arch/arm/mach-xxx).

Most or all of the new code is made buildable outside of 
machine/ARCH_xxx (so COMPILE_TEST).
