[U-Boot] [PATCH V2 1/2] ARM: OMAP3: am3517_evm: Move header to ti_omap3_common.h

Tue Sep 5 23:51:18 UTC 2017


Much of the AM3517 functions are copies of the standard definitions
used in ti_omap3_common.h.  Moving to include a common file
reduces the amount of duplicative code and clutter.  A few
AM3517 specific functions (like EMIF4) are explictly defined
and a few items are undefined or redefined, but overall the number
of lines of code shink.
