It is structured with a platform driver that mainly does identification of the machines. It might trigger loading of the actual device drivers by attaching devices to the platform bus. The identification is vendor specific, parsing a special binary DMI entry. The implementation of that platform identification is applied on pmc_atom clock quirks in the final patch. It is all structured in a way that we can easily add more devices and more platform drivers later. Internally we have some more code for hardware monitoring, more leds, watchdogs etc. This will follow some day.
