Define both uarts in kirkwood.dtsi as they are common to all kirkwood
SoCs. Each board may enable all or none of them, so they are disabled
by default. uart0 is enabled for the dreamplug.
tclk can vary for each board, so we leave it undefined in the kirkwood
dtsi. Each board can then set it as appropriate when enabling the uart.

Move all dreamplug-specific code out of board-dt.c and into
board-dreamplug.c. This way new boards that are added during the
conversion to fdt don't clutter up board-dt.c.
Signed-off-by: Jason Cooper <jason@lakedaemon.net>
We need to absorb kirkwood_init() into kirkwood_dt_init() so that as we
convert drivers, we can remove the platform call, eg
kirkwood_rtc_init(). This maintains compatibility with non-fdt
configurations because they still call kirkwood_init() in common.c.
As drivers are converted, we will reinstate the 'static' qualifier in
common.c.

board-dt-tegra*.c should support any board using Tegra when booted using
device tree. Instead of explicitly listing all the supported boards,
which requires a kernel change for each new board, list the supported SoC
model instead.
Note that the board files do currently have explicit support for setting
up each board's pinmux. However, it's fairly likely that at least the
basic devices on any new board will work just fine as set up by the boot-
loader, and the pinmux data should be moving into device tree soon anyway.

The HP iPAQ hx4700 has 128Mb of flash provided by two Intel StrataFlash devices.
The hx4700 platform configuration defines a single 128Mb flash resource,
resulting in the MTD physmap-flash driver probing the first device only and
presuming the second device is identical:
physmap platform flash device: 08000000 at 00000000
physmap-flash: Found 2 x16 devices at 0x0 in 32-bit bank. Manufacturer ID 0x000089 Chip ID 0x008816
physmap-flash: Found 2 x16 devices at 0x4000000 in 32-bit bank

physmap-flash: 2 set(s) of 2 interleaved chips --> 32 partitions of 4096 KiB
Unfortunately the two devices are not identical. The first has a device ID of
0x8816, identifying a bottom parameter device. The second has a device ID of
0x8813, identifying a top parameter device. By not probing the second device,
physmap-flash does not discover the correct block sizes.
This patch splits the configuration into two 64Mb flash resources, forcing
physmap-flash to probe both devices and thus discover the correct block sizes:
physmap platform flash device: 04000000 at 00000000
physmap-flash: Found 2 x16 devices at 0x0 in 32-bit bank. Manufacturer ID 0x000089 Chip ID 0x008816

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.

The patch series to re-factor PCI's 'latency timer' setup (re:

remove the ARM specific definition of 'pcibios_max_latency' once such

In the series, patch 2/16 (commit 168c8619fd) converted the ARM
specific version of 'pcibios_set_master()' to a non-inlined version.
This was done in preperation for hosting it up into PCI's core, which
was done in patch 10/16 (commit 96c5590058) of the series (and
where the removal of ARM's 'pcibios_max_latency' was overlooked).

Bootup with lockdep enabled has been broken on v7 since b46c0f7465
("ARM: 7321/1: cache-v7: Disable preemption when reading CCSIDR").
This is because v7_setup (which is called very early during boot) calls
v7_flush_dcache_all, and the save_and_disable_irqs added by that patch
ends up attempting to call into lockdep C code (trace_hardirqs_off())
when we are in no position to execute it (no stack, MMU off).
Fix this by using a notrace variant of save_and_disable_irqs. The code
already uses the notrace variant of restore_irqs.

This set of changes are fixing various section mismatch warnings which
look to be completely valid. Primerily, those which are fixed are those
which can cause oopses by manipulation of driver binding via sysfs. For
example: calling code marked __init from driver probe __devinit
functions.
Some of these changes will be reworked at the next merge window when the
underlying reasons are sorted out. In the mean time, I think it's
important to have this fixed for correctness.
Also included in this set are fixes to various error messages in OMAP -
including making them gramatically correct, fixing a few spelling
