The OMAP2+ General-Purpose Memory Controller (GPMC) driver
should eventually be moved from arch/arm/mach-omap2 to
drivers/memory. Unfortunately this is not trivial since it
includes headers files that still resides under mach-omap2
and can't be moved easilly.

This patch is the first step for taking the gpmc driver
outside arch/arm/mach-omap2 by moving its related headers
files to include/linux/platform_data.

Hi Tony,

I wonder what's your plan to move drivers outside of mach-omap2.
Currently this driver still includes soc.h and omap_device.h
that are on mach-omap2.

If we want to move out these two headers files then also omap
hwmod and per SoC family headers have to be moved out mach-omap2.

Do you want me to do a follow-up patch-set to move all these
headers out of mach-omap2 so the gpmc and other drivers can
be moved to drivers/? 

Is include/linux/platform_data the right place to put these
headers or there is a better place for them?

Thanks a lot and best regards,
Javier
