[PATCH 03/51] ARM: imx: use MXxy_IO_P2V macros to setup static mappings
Uwe Kleine-König

Wed Nov 17 16:29:31 EST 2010
This makes less code rely on the virtual constants.
To further simplify code and reduce the needed boilerplate when
defining the static mappings a new helper macro is defined in
mach/hardware.h.
