It'd be nice to have a silent Kconfig entry that selects from ARCH_SUNXI that
sets this dependency, instead of having it from the architecture code. This
pushes down the dependency to the right level.

Do you mean something like :
config ARCH_SUNXI
        ...
        select SUNXI_PLATFORM

And have

config SUNXI_PLATFORM
        select SUNXI_DEPENDENCY_1
        select SUNXI_DEPENDENCY_2

where SUNXI_PLATFORM drives the dependencies for both ARM and ARM64 ?

If so, where would you like SUNXI_PLATFORM to reside ? drivers/platform ?
Also, AFAIK, the arm64 port doesn't have the full support for the required
bits for SUNXI yet, which could be handled in the common place with ( && 
!ARM64).

Andre, please feel free to correct my assessment above.


Thanks
Suzuki
