I am unsure this even applies to all CCM versions.

Maybe Sascha has an opinion on whether they should be kept or removed? > ./include/mach/imx/habv3-imx25-gencsf.h There's i.MX25 support in drivers/hab, which I assume was added for a reason, so some out-of-tree board is likely including this. > ./include/mach/imx/iomux-mx21.h > ./include/mach/imx/iomux-mx35.h > ./include/mach/imx/iomux-mx50.h I think these definitions should remain.
