/*
* Address map functions for Marvell EBU SoCs (Kirkwood, Armada
* 370/XP, Dove, Orion5x and MV78xx0)
*
* This file is licensed under the terms of the GNU General Public
* License version 2. This program is licensed "as is" without any
* warranty of any kind, whether express or implied.
*
* 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 mvebu_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(),
* mvebu_mbus_add_window_remap_flags() and
* mvebu_mbus_del_window(). Since the (target, attribute) values
* differ from one SoC family to another, the API uses a 'const char
* *' string to identify devices, and this driver is responsible for
* knowing the mapping between the name of a device and its
* corresponding (target, attribute) in the current SoC family.
*
* - Provides a debugfs interface in /sys/kernel/debug/mvebu-mbus/ to
* see the list of CPU -> SDRAM windows and their configuration
* (file 'sdram') and the list of CPU -> devices windows and their
* configuration (file 'devices').
