The option should probably go into arch/arm64/Kconfig. Possibly you can make
it a silent option that just gets selected whenever a driver is enabled
that might set the callbacks.

I try to bind it with HISILICON platform.

It should be possible to build the actual driver on all platforms, at
least with COMPILE_TEST.

Sorry, I'm a little confused, can you describe it in detail?

        bool

          Any driver that provides indirect ISA I/O port access should select
          this symbol

        bool "Workaround for nonstandard ISA I/O space on Hisilicon Hi123456 
SoC"
        depends on ARCH_HISI || COMPILE_TEST
        select ARM64_INDIRECT_PIO
        help
          ...
Can it be a submenu of "Platform selection--->Hisilicon SoC Family"?
