10   On typical mainboards, this is purely internal; and it's not needed
11   after board init creates the hard-wired devices.  Some development
12   platforms may not be able to use spi_register_board_info though, and
13   this is exported so that for example a USB or parport based adapter
14   driver could add devices (which it would learn about out-of-band).
