+/**
+ * @defgroup nvodm_discovery ODM Peripheral Discovery Interface
+ *
+ * This is the ODM query interface allowing ODMs to specify the connectivity
+ * of peripherals on their boards to I/Os on an NVIDIA&reg; Application Processor
+ * without modifying the driver libraries.
+ *
+ * All peripherals connected to the application processor are referenced by
+ * their Global Unique Identifier code, or GUID. The GUID is an ODM-defined
+ * 64-bit value (8-character code) that uniquely identifies each peripheral,
+ * i.e., each peripheral will have exactly one GUID, and each GUID will refer
+ * to exactly one peripheral.
+ * 
+ * The implementation of this API is similar to a simple database: tables are
+ * provided by the ODMs that, for every peripheral, define the peripheral's
+ * GUID, and specify the bus, or set of buses, to which the peripheral is
+ * connected. As an example, an audio codec peripheral with GUID 0 could be
+ * connected to the application processor by DAP instance 0, I2C instance 1
+ * (address 0x80), and voltage rail 3. The functions provided by this API
+ * provide facilities enabling the boot process and driver libraries to
+ * enumerate the set of peripherals attached to a specific bus, the set of
+ * peripherals with specific functionality (such as display outputs), and the
+ * set of buses connected to a specific peripheral.
