Not sure why we can't do something like this?

In mx5x.h, 
MX51_PERIP_1 /* Address specific to mx51 */
MX53_PERIP_1 /* Address specific to mx53 */
MX5_PERIP_2 /* Address that is shared to mx51, mx53, and any later mx5X chips */
Then if something like mx57 comes, you can add to mx5x.h the differences with MX57_PERIP_1.
