Ok, I was afraid about something like that and tried first to include it in 
board configuration but that broke something else (at least arm926ejs didn't 
compile any more).

I use it in my board (support of which I'm preparing to send) configuration 
file and I think it is annoying to write a literal constant there which is 
already defined in imx-regs.h.

PPC seems to use a predefined macro from asm/immap_8xxx.h files. Where is that 
file included?
