The boards in board/davinci/da8xxevm/ define pinmux_config[] vectors that contain pinmux configurations for emac, uarts, memory controllers... In an earlier patch such pinmux configurations were added to the arch tree. This patch makes the hawkboard use these definitions instead of defining its own.
