TI armv7 based SoCs are based on two architectures - one based on OMAP generation architecture and others based on Keystone architecture. Many of the options are architecture specific, however a lot are common with v7 architecture. So, step 1 will be to move out OMAP specific stuff from ti_armv7_common into a ti_armv7_omap.h header which is then used by all the relevant architecture headers.
