why mx28 soc io virt base defined as 0xf0000000?

[ask]

Hi all,

The below macro is defined in arch/arm/mach-mx28/include/mach/mx28.h in a file.

#define MX28_SOC_IO_VIRT_BASE 0xF0000000

Please any one can explain me the reason?

Thanks in advace.

Hi ask

no special reason, but this figure makes code with

better visibility, also there is unification with i.MX23 codes.

Best regards

igor
