With this change, IMX_IO_P2V(MX50_AIPS2_BASE_ADDR) == IMX_IO_P2V(MX51_AIPS2_BASE_ADDR) == IMX_IO_P2V(MX53_AIPS2_BASE_ADDR). This change was tested for mapping conflicts using the iop2v script found at git://git.pengutronix.de/git/ukl/imx-iop2v.git and by performing a bootup of a default build using imx_v6_v7_defconfig on a imx51 babbage board and imx53 loco board. The comments were modified to reflect the output given by the script which shows the virtual address mappings.
