+ * The Marvell EBU SoCs have a configurable physical address space:
+ * the physical address at which certain devices (PCIe, NOR, NAND,
+ * etc.) sit can be configured. The configuration takes place through
+ * two sets of registers:
+ *
+ * - One to configure the access of the CPU to the devices. Depending
+ *   on the families, there are between 8 and 20 configurable windows,
+ *   each can be use to create a physical memory window that maps to a
+ *   specific device. Devices are identified by a tuple (target,
+ *   attribute).
+ *
+ * - One to configure the access to the CPU to the SDRAM. There are
+ *   either 2 (for Dove) or 4 (for other families) windows to map the
+ *   SDRAM into the physical address space.
+ *
+ * This driver:
+ *
+ * - Reads out the SDRAM address decoding windows at initialization
+ *   time, and fills the mbus_dram_info structure with these
+ *   informations. The exported function mv_mbus_dram_info() allow
+ *   device drivers to get those informations related to the SDRAM
+ *   address decoding windows. This is because devices also have their
+ *   own windows (configured through registers that are part of each
+ *   device register space), and therefore the drivers for Marvell
+ *   devices have to configure those device -> SDRAM windows to ensure
+ *   that DMA works properly.
+ *
+ * - Provides an API for platform code or device drivers to
+ *   dynamically add or remove address decoding windows for the CPU ->
+ *   device accesses. This API is mvebu_mbus_add_window_by_id(),
+ *   mvebu_mbus_add_window_remap_by_id() and
+ *   mvebu_mbus_del_window().
