Here's the new MBus DT binding, implementing the changes proposed
by Thomas when we discussed the previous patchset:
http://www.spinics.net/lists/arm-kernel/msg257170.html
As far as I know, this round fixes *all* the concerns raised in the past
and therefore I'd like to get Acked-by's from all the parties involved
on the respective patches, and particularly for the DT binding.
If there's anything left to review, we'll be glad to fix it quickly,
so don't hesitate in providing your feedback!
I'm sure many of you are dying to test this new MBus thing, so to make
it easier for those courageous enough, I've pushed a public branch:
https://github.com/MISL-EBU-System-SW/mainline-public/tree/marvell-mvebu-mbus-v7
This patchset is based on v3.11-rc1.
Changelog
---------
v7:
* Add two optional properties pcie-{mem,io}-aperture to the MBus node
defining the PCIe mem and IO region apertures.
* Encode the PCIe port in the second cell of the ranges entries, using
the PCIe slot; and remove such encoding from the first cell, since it
was violating the specification.
Quoting Jason Gunthorpe:
""" [...] the OF spec says that the phys.hi fields of the child address
spaces in the "ranges" property for PCI does not contain the same
information as "reg" property entries within PCI nodes. The only information
that is present in "ranges" phys.hi entries are the non-relocatable,
prefetchable and the PCI address space bits for which the entry applies.
I.e., only the n, p and ss bits are present; the bbbbbbbb, ddddd, fff and
rrrrrrrr fields are 0."""
v6:
* Change the PCIe ranges translations encoding, removing the big fake
window encoded as MBUS_ID(0xf0, 0x02) by an array of entries representing
the PCIe real windows with full 4 GiB size.
* The corresponding PCIe port is selected by encoding the bus in the first cell
of the PCIe controller node ranges entry.
* Remove the name-based MBus window allocation API, replacing it by an
ID-based API.
v5:
* Add a required a 'controller' property to specify a phandle containing
the MBus controller MMIO registers.
v4:
* 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.
v3:
* 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.
v2:
* Use the preprocessor on the DT and define a macro for the window ID.
* 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.
v1:
* Initial proposal

* [RESEND PATCH v7 00/22] MBus DT binding: The return of PCIe

Here's the new MBus DT binding, implementing the changes proposed
by Thomas when we discussed the previous patchset:
http://www.spinics.net/lists/arm-kernel/msg257170.html
As far as I know, this round fixes *all* the concerns raised in the past
and therefore I'd like to get Acked-by's from all the parties involved
on the respective patches, and particularly for the DT binding.
If there's anything left to review, we'll be glad to fix it quickly,
so don't hesitate in providing your feedback!
I'm sure many of you are dying to test this new MBus thing, so to make
it easier for those courageous enough, I've pushed a public branch:
https://github.com/MISL-EBU-System-SW/mainline-public/tree/marvell-mvebu-mbus-v7
This patchset is based on v3.11-rc1.

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.

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.

* [RESEND PATCH v7 03/22] ARM: kirkwood: Move to ID based MBus window creation

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
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.

* [RESEND PATCH v7 05/22] ARM: orion5x: Move to ID based window creation
@ 2013-07-15 14:57 ` Ezequiel Garcia
0 siblings, 0 replies; 60+ messages in thread
From: Ezequiel Garcia @ 2013-07-15 14:57 UTC (permalink / raw)
To: linux-arm-kernel
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
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.

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 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.

+
+- reg: Device's register space.
+ Two entries are expected (see the examples below):
+ the first one controls the devices decoding window and
+ the second one controls the SDRAM decoding window.
+
+Example:
+
+ soc {
+ compatible = "marvell,armada370-mbus", "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;

+ reg = <0x20000 0x100>, <0x20180 0x20>;
+ };
+
+ /* more children ...*/
+ };
+ };
+
+** 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
+ MBUS_ID(0x01, 0xe0) 0 0 0xfff00000 0x100000>;
+
+ bootrom {
+ compatible = "marvell,bootrom";
+ reg = <MBUS_ID(0x01, 0xe0) 0 0x100000>;
+ };
+
+ /* other children */
+ ...
+
+ internal-regs {
+ compatible = "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 MBUS_ID(0xf0, 0x01) 0 0x100000>;
+
+ mbusc: mbus-controller@20000 {
+ compatible = "marvell,mbus-controller";
+ reg = <0x20000 0x100>, <0x20180 0x20>;
+ };
+
+ /* other children */
+ ...
+ };
+ };
+
+
+** 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 */

+ 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
+ MBUS_ID(0x01, 0xe0) 0 0 0xfff00000 0x100000>;
+
+ bootrom {
+ compatible = "marvell,bootrom";
+ reg = <MBUS_ID(0x01, 0xe0) 0 0x100000>;
+ };
+
+ /* other children */
+ ...
+
+ internal-regs {
+ compatible = "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 MBUS_ID(0xf0, 0x01) 0 0x100000>;
+
+ mbusc: mbus-controller at 20000 {
+ compatible = "marvell,mbus-controller";
+ reg = <0x20000 0x100>, <0x20180 0x20>;
+ };
+
+ /* other children */
+ ...
+ };
+ };
+
+
+** 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.

* [RESEND PATCH v7 11/22] PCI: mvebu: Adapt to the new device tree layout
@ 2013-07-15 14:57 ` Ezequiel Garcia

To: linux-arm-kernel
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
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.

* [RESEND PATCH v7 13/22] bus: mvebu-mbus: Remove name -> target, attribute mapping tables

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.

The address decoding window to access the BootROM should not be
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.

* [RESEND PATCH v7 21/22] ARM: mvebu: Relocate Armada 370/XP DeviceBus device tree nodes
@ 2013-07-15 14:57 ` Ezequiel Garcia

From: Ezequiel Garcia @ 2013-07-15 14:57 UTC (permalink / raw)
To: linux-arm-kernel
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.

* [RESEND PATCH v7 22/22] ARM: mvebu: Relocate Armada 370/XP PCIe device tree nodes
@ 2013-07-15 14:57 ` Ezequiel Garcia
0 siblings, 0 replies; 60+ messages in thread
From: Ezequiel Garcia @ 2013-07-15 14:57 UTC (permalink / raw)
To: linux-arm-kernel
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.

Can you comment on this DT binding? Notice this is the outcome of a
lengthy discussion and has been already agreed by Arnd and Jason Gunthorpe.
If it looks OK, I'd like to have formal Acked-by's so Jason Cooper can merge it.
On the other side, given we've decided to mark some bindings as 'unstable'
or 'staging' maybe Jason can merge it so it can be in linux-next.
This way developers can actually start using this, and complaining if
there's anything to complain.
If we leave it as a patchset floating in mailing-lists it's hardly going
to get tested.
Does this approach make sense?
Thanks a lot!

Any ideas?
Thanks

The patchset works only for Armada 370 and Armada XP SoC, not for Kirkwood.
For some reason I was completely sure there wasn't any DT-enabled Kirkwood
boards with PCIe support.
I apologize for not noticing this before!
My plan was to get this patchset acked/merged and then add MBus DT to Kirkwood.
The reason for this is that it's a simple change, but probably *very* intrusive
on the DTS files.
Of course, this plan was based on the assumption that the wasn't breaking
anything.
However, now I guess there's no other solution than adding Kirkwood to the
patchset. So unless anyone has any better idea, I'll be sending a v8.
Thanks again for the test!

I had a quick look at Dove and Orion5x. It looks like there are none

There are some Dove and Orion5x with PCIe support, but none of them are
