Thomas Petazzoni 5686a1e5aa bus: mvebu: pass the coherency availability information at init time
Until now, the mvebu-mbus was guessing by itself whether hardware I/O
coherency was available or not by poking into the Device Tree to see
if the coherency fabric Device Tree node was present or not.

However, on some upcoming SoCs, the presence or absence of the
coherency fabric DT node isn't sufficient: in CONFIG_SMP, the
coherency can be enabled, but not in !CONFIG_SMP.

In order to clean this up, the mvebu_mbus_dt_init() function is
extended to get a boolean argument telling whether coherency is
enabled or not. Therefore, the logic to decide whether coherency is
available or not now belongs to the core SoC code instead of the
mvebu-mbus driver itself, which is much better.

Andrew Lunn dab7dfb6c0 ARM: kirkwood: Separate board-dt from common and pcie code.
In order to be able to move DT support into mach-mvebu, the DT code
needs to be cleanly separated from common and pcie code. Import the
needed bits of these files into board-dt.c. The "common" code then
becomes purely legacy, supporting non-DT boards, so reflect this in

Linus Torvalds f9efbce633 ARM: SoC DT updates for 3.13
Most of this branch consists of updates, additions and general churn of
 the device tree source files in the kernel (arch/arm/boot/dts). Besides
 that, there are a few things to point out:
 
 - Lots of platform conversion on OMAP2+, with removal of old board files
   for various platforms.
 - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
 - Some updates to pinctrl and other subsystems. Most of these are for
   DT-enablement of the various platforms and acks have been collected.

kirkwood_setup_wins is the last manual caller of mbus in kirkwood, don't
call it for DT boards and rely on the DT having a mbus node with

Move all the mbus ranges properties for all boards into kirkwood.dtsi,
since they are currently all the same.

This makes the DT self consistent, since the physical address of the
NAND and CRYPTO are both referenced internally. The arbitary Linux
constants KIRKWOOD_NAND_MEM_PHYS_BASE and KIRKWOOD_SRAM_PHYS_BASE
no longer have to match the DT values.

Linus Torvalds 40e71e7015 ARM SoC board specific changes
These are 18 branches on 9 platforms with board specific changes, mostly
 for defconfig files, but nothing really exciting in here.
 
 Since the shmobile platform still uses board files for some of the newer
 machines, we get a few changes there as the result of drivers getting
 enabled for those boards. This causes some conflicts with contents getting
 added from multiple branches in sh-mobile specific files. Renesas is
 putting a lot of work into migrating to device-tree based setup, which
 will make all those files obsolete in the future and avoid both the

  Since the shmobile platform still uses board files for some of the

  getting enabled for those boards.  This causes some conflicts with

This commit converts the Marvell DB-88F6281/DB-88F6282 board to the
Device Tree. In fact, the code was supporting two different boards:
one with the 6281 SoC variant, and one with the 6282 SoC variant. The
difference between the two being that the 6281 has one PCIe interface,
and the 6282 has two PCIe interfaces.

In order to handle that with the Device Tree, we create a
'kirkwood-db.dtsi' file that contains the definitions common to both
boards, and 'kirkwood-db-88f6281.dts' and 'kirkwood-db-88f6282.dts'
for the definitions specific to each board. This is similar to what is
done for the QNAP TS219 Kirkwood platform.

We have kept one single Kconfig option, just like it was before.

Linus Torvalds fcba914542 ARM: arm-soc platform updates for 3.10, part 3
This is the third and smallest of the SoC specific updates.
 Changes include:
 
 * SMP support for the Xilinx zynq platform
 * Smaller imx changes
 * LPAE support for mvebu
 * Moving the orion5x, kirkwood, dove and mvebu platforms
   to a common "mbus" driver for their internal devices.
 
 It would be good to get feedback on the location of the "mbus"
 driver. Since this is used on multiple platforms may potentially
 get shared with other architectures (powerpc and arm64), it
 was moved to drivers/bus/. We expect other similar drivers to
 get moved to the same place in order to avoid creating more
 top-level directories under drivers/ or cluttering up the
 messy drivers/misc/ even more.

Thomas Petazzoni 5cc0673a67 arm: mach-kirkwood: convert to use mvebu-mbus driver
This commit migrates the mach-kirkwood platforms to use the mvebu-mbus
driver and therefore removes the Kirkwood-specific addr-map code.

The kirkwood_init_early() function is now responsible for initializing
the mvebu-mbus driver by calling mvebu_mbus_init().

The address decoding windows are now registered in the
kirkwood_setup_wins() function. It is worth noting that the four PCIe
address decoding windows will ultimately no longer have to be
registered here: it will be done automatically by the PCIe driver once
Kirkwood has been migrated to use the upcoming mvebu PCIe driver.

- SDRAM memory: 256MB DDR2-800 (2x128MB x8) 400Mhz
- 1 Ethernet Gigabit port (PHY MARVELL 88E1318)
- SPI flash, NOR 512KB
- 1 push button
- 2 LEDs (red and blue)

There is no EEPROM and no USB ports embedded.

Sebastian Hesselbarth 7bf5b408b4 ARM: kirkwood: fix to retain gbe MAC addresses for DT kernels
The ethernet controller used on kirkwood looses its MAC address
register contents when the corresponding clock is gated. As soon as
mv643xx_eth is built as module, the clock gets gated and when loading
the module, the MAC address is gone.

Proper DT support for the mv643xx_eth driver is expected soon, so we add
a workaround to always enable ge0/ge1 clocks on kirkwood. This workaround
is also already used on non-DT kirkwood kernels.

 "This is a branch with updates for Marvell's mvebu/kirkwood platforms.
  They came in late-ish, and were heavily interdependent such that it
  didn't make sense to split them up across the cross-platform topic
  branches.  So here they are (for the second release in a row) in a
  branch on their own."
