+ * unique device: a platform_device entry in fsl_plat_devs[] plus
+ * associated device information in its platform_data structure.
+ *
+ * A chip is described by a set of unique devices.
+ *
+ * Each sub-arch has its own master list of unique devices and
+ * enumerates them by enum fsl_devices in a sub-arch specific header
+ *
+ * The platform data structure is broken into two parts. The
+ * first is device specific information that help identify any
+ * unique features of a peripheral. The second is any
+ * information that may be defined by the board or how the device
+ * is connected externally of the chip.
+ *
+ * naming conventions:
+ * - platform data structures: <driver>_platform_data
+ * - platform data device flags: FSL_<driver>_DEV_<FLAG>
+ * - platform data board flags: FSL_<driver>_BRD_<FLAG>
