Ah, thanks for the explanation.

Since the clps7111 based asm/hardware/*.h files are not shared with ep93xx,
I guess it makes sense to move them to mach-clps711x/include/mach/*.h as part of
this cleanup series, right?

I found these clps711x specific files:


Out of these, only the first one is used in two places outside of
arch/arm/mach-clps711x, the serial and the fb driver, which could
be changed to use mach/hardware.h instead.
