+ * 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

- * 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
