I am a bit sceptical about these macros. Most i/o code in the kernel is
in the form of "<base address> + <register offset>". For one thing,
that model keeps the register defines clean and means people don't have
to go reaching for specs all the time.
Would you be content with replacing "func->num * 0x100" with a macro so
that the code becomes something like:
SDIO_FBR_BASE(func->num) + SDIO_FBR_STD_IF
