See the previous version of this patchset for further context:

http://www.spinics.net/lists/arm-kernel/msg252656.html

In the current patchset, the proposal is slightly different.
As an example of the current status, here's an extract of a device tree:

	#define MBUS_ID(target,attributes) (((target) << 24) | ((attributes) << 16))

	soc {
		compatible = "marvell,armadaxp-mbus";
		reg = <0 0xd0020000 0 0x100>, <0 0xd0020180 0 0x20>;

		ranges = <MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000   /* internal-regs */
			  MBUS_ID(0xf0, 0x02) 0xe0000000 0 0xe0000000 0x8100000  /* pcie */
			  MBUS_ID(0x01, 0x1d) 0 0 0xfff00000 0x100000
			  MBUS_ID(0x01, 0x2f) 0 0 0xf0000000 0x8000000>;

		bootrom {
			compatible = "marvell,bootrom";
			reg = <MBUS_ID(0x01, 0x1d) 0 0x100000>
		};

		devbus-bootcs {
			status = "okay";

			/* NOR */
			nor {
				compatible = "cfi-flash";
				reg = <0 0x8000000>;
				bank-width = <2>;
			};
		};

		pcie-controller {
			compatible = "marvell,armada-xp-pcie";
			status = "okay";
			device_type = "pci";

			#address-cells = <3>;
			#size-cells = <2>;

			ranges =
			       <0x82000000 0 0x40000 MBUS_ID(0xf0, 0x01) 0x40000 0 0x00002000   /* Port 0.0 registers */
				0x82000000 0 0x42000 MBUS_ID(0xf0, 0x01) 0x42000 0 0x00002000   /* Port 2.0 registers */
				0x82000000 0 0x44000 MBUS_ID(0xf0, 0x01) 0x44000 0 0x00002000   /* Port 0.1 registers */

				0x82000000 0 0xe0000000 MBUS_ID(0xf0, 0x02) 0xe0000000 0 0x08000000   /* non-prefetchable memory */

			pcie@1,0 {
				/* Port 0, Lane 0 */
				status = "okay";
			};
		};

		internal-regs {
			compatible = "simple-bus";
			#address-cells = <1>;
			#size-cells = <1>;
			...
		};
	};

This patchset is based on v3.10-rc4, with Jason Cooper's mvebu/regmap branch
applied, and with the mvebu-devbus commit (3edad321b1 in linux-next):
"drivers: memory: Introduce Marvell EBU Device Bus driver"

Changes from v3:
 * Fixed the pcie-controller to mbus address space translations, to match
   a 1:1 mapping between the PCI and CPU busses.

 * Fixed the binding documentation with suggestions from Arnd Bergmann.

 * Added a BootROM sanity check on AXP SMP initialization, as suggested
   by Jason Gunthorpe. This also implied changing slightly the bootrom
   node.

 * Changed the first cell format for the MBus address space.

Changes from v2:
 * Replaced the PCIe mapping with 0xffff0002, to avoid using a representation
   that might correspond to a possible window id.

 * Remove every mbus-node 'ranges' property from the dtsi files. Having them
   on the per-board dts files only makes maintaince less painful.

 * Declare children window size, in the children 'ranges' property, as large
   as possible (4 GiB size) and move the property to the dtsi files.
   The per-board dts, does not need to declare that property now.
 
 * The MBus driver now creates the decoding window using the base address and
   size specified in the mbus-node, instead of using the children entries.

Change from v1:
 * Changed the way the address spaces were declared: the window's base
   addresses are only present in the mbus-node ranges property.
   This makes sense since that information belongs only to the MBus
   address space.

 * Drop the ranges dynamic update, since now the DT translations are complete.
 
 * Replaced the internal register first cell mapping with 0xffff0001, to avoid
   clashing when using 0x00000000.

 * Replaced the PCIe mapping with 0xffff0000.

Thanks a lot!

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.

+Required properties:

+		 marvell,armadaxp-mbus
+
+- reg:		 Device's register space.
+		 Two entries are expected, see the examples below.

+
+- size-cells:    Must be '1'.
+
+- ranges:        Must be set up to provide a proper translation for each child.
+	         See the examples below.
+
+Example:
+
+	soc {
+		compatible = "marvell,armada370-mbus", "simple-bus";
+		reg = <0xd0020000 0x100>, <0xd0020180 0x20>;
+		#address-cells = <2>;
+		#size-cells = <1>;
+	};
+
+** 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
+   AA = 2 for PCI-E
+
+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";
+		reg = <0xd0020000 0x100>, <0xd0020180 0x20>;
+		#address-cells = <2>;
+		#size-cells = <1>;
+
+		ranges = <0xf0010000 0 0 0xd0000000 0x100000
+			  0x011d0000 0 0 0xfff00000 0x100000>;
+
+		bootrom {
+			compatible = "marvell,bootrom";
+			reg = <0 0x100000>;
+		};
+
+		/* other 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";
+		reg = <0xd0020000 0x100>, <0xd0020180 0x20>;
+		#address-cells = <2>;
+		#size-cells = <1>;

+
+
+** 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 acess 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";
+		reg = <0 0xd0020000 0 0x100>, <0 0xd0020180 0 0x20>;
+
+		ranges = <MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000   /* internal-regs */

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 address decoding window to access the BootROM should not be
allocated programatically, but declared in the device tree.

Instead of allocating it, we add a check to verify the DT has
declared a valid node to access the BootROM.

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.

Greg,

I'm Ccing you, since you're carrying the mvebu-devbus driver in your trees.
This patch should be applied only after the MBus DT binding is accepted
and/or merged; although I doubt we will see that happening any time soon.

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 PCIe nodes out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the
hardware.

Since this MBus series is most likely for v3.12, Greg's tree will be
merged by then.  At which time, we can decide if it's best to keep the
series together or continue to send devbus changes through him.  I'm
fine either way, and but I have a preference for keeping the series
together.

thx,

Jason.

Ok, I'll ignore this then, as it shouldn't go into 3.11, and I don't
have trees that go beyond that at this point in time.
