question: where is linux/ide-platform.h header?
answer: there isn't one, as it's not needed. The reason for using
platform devices is so we get _away_ from this ridiculous static
set of
definitions for I/O addresses and IRQs that are sprinkled around a lot
of these drivers.
i wrote wrong file name:
where is linux/platform_device.h file?
