Jason Cooper 3d468b6d60 ARM: kirkwood: add dreamplug (fdt) support.
Initially, copied guruplug-setup.c and did s/guruplug/dreamplug/g.
Then, switched to SPI based NOR flash.

After talking to Arnd Bergman, chose an incremental approach to adding
devicetree support.  First, we use the dtb to tell us we are on the
dreamplug, then we gradually port over drivers.

Driver porting will start with the uart (see next patch), and progress
from there.  Possibly, spi/flash/partitions will be next.

When done, board-dt.c will no longer be dreamplug specific, and dt's can
be made for the other kirkwood boards.

Stephen Warren 6f74dc9bc8 gpio: tegra: Dynamically allocate IRQ base, and support DT
Enhance the driver to dynamically allocate the base IRQ number, and
create an IRQ domain for itself. The use of an IRQ domain ensures that
any device tree node interrupts properties are correctly parsed.

Describe interrupt-related properties in the device tree binding docs,
and the contents of "child" node interrupts property.

Update tegra*.dtsi to specify the required interrupt-related properties.

Finally, remove the definition of TEGRA_GPIO_TO_IRQ; this macro no longer
gives correct results since the IRQ numbers for GPIOs are dynamically
allocated.

Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only
tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous
lack of this feature recently caused me to have very confusing "git
bisect" results.

For ARM, it's obvious what to add to $(targets). I'm not familiar enough
with other architectures to know what to add there. Powerpc appears to
already add various .dtb files into $(targets), but the other archs may
need something added to $(targets) to work.

Linus Torvalds dfc1ebe766 Device tree conversions for samsung and tegra
Both platforms had some initial device tree support, but this adds
 much more to actually make it usable.
 
 This is where the really nasty conflicts in the samsung platform
 start, due to some files getting moved around and combined in the
 'restart' branch that has already gone into mainline through
 Russell's tree.

pdeschrijver@nvidia.com 0d4f74792e arm/tegra: convert tegra20 to GIC devicetree binding
Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the
interrupt definitions in the dts files according to
Documentation/devicetree/bindings/arm/gic.txt

v3 (swarren):
* Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it.
  - Even with a dummy replacement if !CONFIG_OF, the reference from
    tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd
  - It's plausible that tegra_dt_irq_match[] may need to contain more
    entries in the future, and defining what they are seems more suitable
    for board-dt.c than irq.c
v2 (swarren):
* Removed some stale GIC init code from board-dt.c
* Undid some accidental 0x -> 0x0 search/replace.

Stephen Warren 1292c12959 arm/dt: tegra: Fix SDHCI nodes to match board files
Mark any SDHCI controllers that aren't registered by the board files as
disabled in the device-tree files.

In practice, these controllers:

* Have nothing hooked up to them at all, or
* For ports intended for SDIO usage, the drivers for anything that might
  be attached are not in the device-tree yet. If/when drivers appear, the
  SD/MMC port can be re-enabled.

The only possible exception is TrimSlice's mico SD slot, but that wasn't
enabled in the board files before anyway, and doesn't work when all the
SDHCI controllers are enabled anyway.

Mark any serial ports that aren't registered by the board files as disabled
in the device-tree files.

In practice, none of the now-disabled ports ended up succeeding device
probing because of the missing clock-frequency property. However,
explicitly marking the devices disabled has the advantage of squashing
the dev_warn() the failed probe causes, and documenting that we intend
the port not to be used, rather than accidentally left out the property.

The command-lines present in the existing /chosen node are not necessarily
correct for all users. Ideally, we should simply use the command-line
supplied by the boot-loader.

In fact, using the boot-loader's cmdline is quite easy; either the
bootloader fully supports DT, in which case it can modify the DT passed
to the kernel to include its command-line, or CONFIG_APPENDED_DTB can
be used in conjunction with CONFIG_ARM_ATAG_DTB_COMPAT, and the kernel
will substitute the bootloader's command-line into the DT.

This first basic support will be populated as drivers and boards will be

The generic board file still takes advantage of platform data for early serial

Nicolas Pitre b90b9a3825 ARM: zImage: allow supplementing appended DTB with traditional ATAG data
Some old bootloaders can't be updated to a device tree capable one,
yet they provide ATAGs with memory configuration, the ramdisk address,
the kernel cmdline string, etc.  To allow a device tree enabled
kernel to be used with such bootloaders, it is necessary to convert those
ATAGs into FDT properties and fold them into the DTB appended to zImage.

Currently the following ATAGs are converted:

	ATAG_CMDLINE
	ATAG_MEM
	ATAG_INITRD2

If the corresponding information already exists in the appended DTB, it
is replaced, otherwise the required node is created to hold it.

The code looks for ATAGs at the location pointed by the value of r2 upon
entry into the zImage code.  If no ATAGs are found there, an attempt at
finding ATAGs at the typical 0x100 offset from start of RAM is made.
Otherwise the DTB is left unchanged.

Thisstarted from an older patch from John Bonesio <bones@secretlab.ca>,
with contributions from David Brown <davidb@codeaurora.org>.

Nicolas Pitre 5ffb04f669 ARM: zImage: make sure appended DTB doesn't get overwritten by kernel .bss
The appended DTB gets relocated with the decompressor code to get out
of the way of the decompressed kernel.  However the kernel's .bss section
may be larger than the relocated code and data, and then the DTB gets
overwritten.  Let's make sure the relocation takes care of moving zImage
far enough so no such conflict with .bss occurs.

Thanks to Tony Lindgren <tony@atomide.com> for figuring out this issue.

While at it, let's clean up the code a bit so that the wont_overwrite
symbol is used while determining if a conflict exists, making the above
change more precise as well as eliminating some ARM/THUMB alternates.
