-name specified by each, to find the appropriate driver. It then calls
-device_bind() to create a new device and bind' it to its driver. This will
-call the device's bind() method.
+   - Scan the U_BOOT_DEVICE() definitions. U-Boot looks up the name specified
+by each, to find the appropriate U_BOOT_DRIVER() definition. In this case,
+there is no path by which driver_data may be provided, but the U_BOOT_DEVICE()
+may provide platdata.
 
    - Scan through the device tree definitions. U-Boot looks at top-level
 nodes in the the device tree. It looks at the compatible string in each node
-and uses the of_match part of the U_BOOT_DRIVER() structure to find the
-right driver for each node. It then calls device_bind() to bind the
-newly-created device to its driver (thereby creating a device structure).
-This will also call the device's bind() method.
+and uses the of_match table of the U_BOOT_DRIVER() structure to find the
+right driver for each node. In this case, the of_match table may provide a
+driver_data value, but platdata cannot be provided until later.
+
+For each device that is discovered, U-Boot then calls device_bind() to create a
+new device, initializes various core fields of the device object such as name,
+uclass & driver, initializes any optional fields of the device object that are
+applicable such as of_offset, driver_data & platdata, and finally calls the
+driver's bind() method if one is defined.
 
 At this point all the devices are known, and bound to their drivers. There
 is a 'struct udevice' allocated for all devices. However, nothing has been

+ * A mailbox is a hardware mechanism for transferring small fixed-size messages
+ * and/or notifications between the CPU on which U-Boot runs and some other
+ * device such as an auxiliary CPU running firmware or a hardware module.
+ *
+ * Data transfer is optional; a mailbox may consist solely of a notification
+ * mechanism. When data transfer is implemented, it is via HW registers or
+ * FIFOs, rather than via RAM-based buffers. The mailbox API generally
+ * implements any communication protocol enforced solely by hardware, and
+ * leaves any higher-level protocols to other layers.
+ *
+ * A mailbox channel is a bi-directional mechanism that can send a message or
+ * notification to a single specific remote entity, and receive messages or
+ * notifications from that entity. The size, content, and format of such
+ * messages is defined by the mailbox implementation, or the remote entity with
+ * which it communicates; there is no general standard at this API level.
+ *
+ * A driver that implements UCLASS_MAILBOX is a mailbox provider. A provider
+ * will often implement multiple separate mailbox channels, since the hardware
+ * it manages often has this capability. mailbox_uclass.h describes the
+ * interface which mailbox providers must implement.
+ *
+ * Mailbox consumers/clients generate and send, or receive and process,
+ * messages. This header file describes the API used by clients.

+ *
+ * @dev: The device which implements the mailbox.
