Olof Johansson 30411c2cad ARM: kirkwood: dockstar: fix header include
The platform data was moved, but this file was introduced in parallel
so didn't get caught in the sweeping changes. Fix it up now.

changes in Kconfig, etc.

We now define all virtual base address constants using IOMEM() so that
those are naturally typed as void __iomem pointers, and we do the
necessary adjustements in the mach-kirkwood code.

Note that we introduce a few temporary additional "unsigned long"

followup patches converting plat-orion functions to void __iomem
pointers as well.

Thomas Petazzoni 40306c8bc0 arm: mach-kirkwood: use plus instead of or for address definitions
Since we are going to use IOMEM() to define many base virtual
addresses, we can no longer use binary or to define the individual
register addresses ("binary or" arithmetic on pointers is not
allowed). Instead, use the more conventional plus operator to do so.

The binary or operators were actually not useful because the low-order
bits of the base address were always zero, so the usage of the binary
or operators was effectively identical to a plus operator.

Valentin Longchamp 0510c8a014 ARM: initial DTS support for km_kirkwood
This is a first attempt to support the km_kirkwood reference design with
a device tree. This km_kirkwood design is present in many Keymile
products. It is based on the Marvell Bobcat SOC which integrates a
Kirkwood CPU next to a big L2 Ethernet Switch. The Kirkwood in the SOC
is very similar to the "normal" one, but there are a few differences.

This initial support is minimal: the kernel can boot with network
(ge0), serial port and NAND functional.

Linus Torvalds 32d687cad3 Merge branch 'fixes-for-3.6' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull DMA-mapping fixes from Marek Szyprowski:
 "Another set of fixes for ARM dma-mapping subsystem.

  Commit e9da6e9905 replaced custom consistent buffer remapping code
  with generic vmalloc areas.  It however introduced some regressions
  caused by limited support for allocations in atomic context.  This
  series contains fixes for those regressions.

  For some subplatforms the default, pre-allocated pool for atomic
  allocations turned out to be too small, so a function for setting its
  size has been added.

  Another set of patches adds support for atomic allocations to
  IOMMU-aware DMA-mapping implementation.

  The last part of this pull request contains two fixes for Contiguous
  Memory Allocator, which relax too strict requirements."

Arnd Bergmann 863e99a8c1 Merge commit 'a849088aa1' from rmk/fixes into cleanup/io-pci
As Stephen Rothwell reports, a849088aa1 ("ARM: Fix ioremap() of
address zero") from the arm-current tree and commit c279443709 ("ARM:
Add fixed PCI i/o mapping") from the arm-soc tree conflict in
a nontrivial way in arch/arm/mm/mmu.c.

Rob Herring explains:
The PCI i/o reserved area has a dummy physical address of 0 and
needs to be skipped by ioremap searches. So we don't set
VM_ARM_STATIC_MAPPING to prevent matches by ioremap. The vm_struct
settings don't really matter when we do the real mapping of the
i/o space.

Since commit a849088aa1 is at the start of the fixes branch
in the arm tree, we can merge it into the branch that contains
the other ioremap changes.

Marek Szyprowski cb01b633ee ARM: Kirkwood: increase atomic coherent pool size
The default 256 KiB coherent pool may be too small for some of the Kirkwood
devices, so increase it to make sure that devices will be able to allocate
their buffers with GFP_ATOMIC flag.

Arnaud Patard (Rtp) b74ffd85e3 ARM: Kirkwood: fix Makefile.boot
While building the dtbs target, one is getting:

make dtbs
make[1]: *** No rule to make target `arch/arm/boot/kirkwood-qnap-ts219.dtb', needed by `arch/arm/boot/dtbs'.  Stop.
make: *** [dtbs] Error 2

The reason is that there's no kirkwood-qnap-ts219.dts file. Update Makefile.boot
to reflect the dts files present.

Arnaud Patard (Rtp) 58569aee5a ARM: Orion: Set eth packet size csum offload limit
The mv643xx ethernet controller limits the packet size for the TX
checksum offloading. This patch sets this limits for Kirkwood and
Dove which have smaller limits that the default.

As a side note, this patch is an updated version of a patch sent some years
ago: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-June/017320.html
which seems to have been lost.
