Now that mbus device tree binding has been introduced, remove the address
decoding window management from this driver.
A suitable 'ranges' entry should be added to the devbus-compatible node in
the device tree, as described by the mbus binding documentation.

We add an API to create MBus address decoding windows from the target
ID and attribute. This function will be used later and deprecate the
current name based scheme.

With the introduction of the ID based MBus API, it's better
to switch to use it instead of the current name based scheme.
This will allow to deprecate the name based API, once every

With the introduction of the ID based MBus API, it's better
to switch to use it instead of the current name based scheme.
This will allow to deprecate the name based API, once every
user is removed.

We introduce a common initialization function mvebu_mbus_common_init()
that will be used by both legacy and device-tree initialization code.
This patch is an intermediate step, which will allow to introduce the
DT binding for this driver in a less intrusive way.

This patch adds the most fundamental device-tree initialization.
We only introduce what's required to be able to probe the mvebu-mbus
driver from the DT. Follow-up patches will extend the device tree binding,
allowing to describe static address decoding windows.

This patch adds static window allocation to the device tree binding.
Each first-child of the mbus-compatible node, with a suitable 'ranges'
property, declaring an address translation, will trigger an address
decoding window allocation.

+
+** MBus address decoding window specification
+
+The MBus children address space is comprised of two cells: the first one for
+the window ID and the second one for the offset within the window.
+In order to allow to describe valid and non-valid window entries, the
+following encoding is used:
+
+ 0xSIAA0000 0x00oooooo
+
+Where:
+
+ S = 0x0 for a MBus valid window
+ S = 0xf for a non-valid window (see below)
+
+If S = 0x0, then:
+
+ I = 4-bit window target ID
+ AA = windpw attribute
+
+If S = 0xf, then:
+
+ I = don't care
+ AA = 1 for internal register
+
+Following the above encoding, for each ranges entry for a MBus valid window
+(S = 0x0), an address decoding window is allocated. On the other side,
+entries for translation that do not correspond to valid windows (S = 0xf)
+are skipped.
+
+ soc {
+ compatible = "marvell,armada370-mbus", "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;
+
+ ranges = <0xf0010000 0 0 0xd0000000 0x100000
+ 0x01e00000 0 0 0xfff00000 0x100000>;
+
+ bootrom {
+ compatible = "marvell,bootrom";
+ reg = <0x01e00000 0 0x100000>;
+ };
+
+ /* other children */
+ ...
+
+ internal-regs {
+ compatible = "simple-bus";
+ ranges = <0 0xf0010000 0 0x100000>;
+
+ mbusc: mbus-controller@20000 {
+ compatible = "marvell,mbus-controller";
+ reg = <0x20000 0x100>, <0x20180 0x20>;
+ };
+
+ /* more children ...*/
+ };
+ };
+
+In the shown example, the translation entry in the 'ranges' property is what
+makes the MBus driver create a static decoding window for the corresponding
+given child device. Note that the binding does not require child nodes to be
+present. Of course, child nodes are needed to probe the devices.
+
+Since each window is identified by its target ID and attribute ID there's
+a special macro that can be use to simplify the translation entries:
+
+#define MBUS_ID(target,attributes) (((target) << 24) | ((attributes) << 16))
+
+Using this macro, the above example would be:
+
+ soc {
+ compatible = "marvell,armada370-mbus", "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;
+
+ ranges = < MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000

+
+
+** About the window base address
+
+Remember the MBus controller allows a great deal of flexibility for choosing
+the decoding window base address. When planning the device tree layout it's
+possible to choose any address as the base address, provided of course there's
+a region large enough available, and with the required alignment.
+
+Yet in other words: there's nothing preventing us from setting a base address
+of 0xf0000000, or 0xd0000000 for the NOR device shown above, if such region is
+unused.
+
+** Window allocation policy
+
+The mbus-node ranges property defines a set of mbus windows that are expected
+to be set by the operating system and that are guaranteed to be free of overlaps
+with one another or with the system memory ranges.
+
+Each entry in the property refers to exactly one window. If the operating system
+choses to use a different set of mbus windows, it must ensure that any address
+translations performed from downstream devices are adapted accordingly.
+
+The operating system may insert additional mbus windows that do not conflict
+with the ones listed in the ranges, e.g. for mapping PCIe devices.
+As a special case, the internal register window must be set up by the boot
+loader at the address listed in the ranges property, since access to that region
+is needed to set up the other windows.
+
+** Example
+
+See the example below, where a more complete device tree is shown:
+
+ soc {
+ compatible = "marvell,armadaxp-mbus", "simple-bus";
+ controller = <&mbusc>;
+
+ ranges = <MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000 /* internal-regs */

We add two optional properties to the MBus DT binding, to encode
the PCIe memory and IO aperture. This allows such information to
be retrieved by -for instance- the pci driver to allocate the
MBus decoding windows.
Correspondingly, and in order to retrieve this information,
we add two new APIs.

The new device tree layout encodes the window's target ID and attribute
in the PCIe controller node's ranges property. This allows to parse
such entries to obtain such information and use the recently introduced
MBus API to create the windows, instead of using the current name based
scheme.

This tables were used together with the name-based MBus window
creation API. Since that's has been removed, we can also remove
the tables.

let's fix the general description of the driver at the beginning

These structures were only different in the mapping tables.
Now that those tables have been removed, it doesn't make any sense
to keep different structures.

allocated programatically, but instead declared in the device tree.

Now that the mbus device tree binding has been introduced, we can
switch over to it.
Also, and since the initialization of the mbus driver is quite
fundamental for the system to work properly, this patch adds a BUG()
in case mbus fails to initialize.

The Armada 370/XP SoC family has a completely configurable address
space handled by the MBus controller.
This patch introduces the device tree layout of MBus, making the
'soc' node as mbus-compatible.
Since every peripheral/controller is a child of this 'soc' node,
this makes all of them sit behind the mbus, thus describing the
hardware accurately.
A translation entry has been added for the internal-regs mapping.
This can't be done in the common armada-370-xp.dtsi because A370
and AXP have different addressing width.

In order to access the SoC BootROM, we need to declare a mapping
(through a ranges property). The mbus driver will use this property
to allocate a suitable address decoding window.

Now that mbus has been added to the device tree, it's possible to
move the DeviceBus out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the hardware.

Now that mbus has been added to the device tree, it's possible to
move the PCIe nodes out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the
hardware.
Moving the PCIe nodes, we now need to introduce an extra cell to
encode the window target ID and attribute. Since this depends on
the PCIe port, we split the ranges translation entries, to correspond
to each MBus window.
