We create two new files, include/configs/ti_armv7_common.h for all of the common IP blocks and related features / commands we share in virtually all of our platforms. We then create include/configs/ti_am335x_common.h for everything common to the am335x SoC leaving just the board specific parts to include/configs/ti_am335x_common.h.
