Yep.

Yes, it should. It's a remnant from the change below...

Yes, forgot to change that.

Ok.

Yes, for consistency. Originally, i was not going to create defines for 
limits used only in one place, as opposed to WAITMONITORINGTIME and 
CLKACTIVATIONTIME.

I used the naming the other define had. Saw no point in changing them. 
They go mostly unused anyway.
Might as well change it.

Ah, copy-paste, there you are again. Luckily this define goes unused, 
because all GPMC_SET_ONE_CD became GPMC_SET_ONE_CD_MAX anyway.
So I'll delete that. Quite a keen eye, though ;)
