Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.
This moves such data out of the omap include directories

As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.
Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.
The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.
Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.
Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.
Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.
While at it, also sort some of the includes in the standard way.

into cleanup-sparseirq
Changes for GPMC (General Purpose Memory Controller) that take it
closer for being just a regular device driver.
Remove the ancient omap specific atags that are no longer needed.
At some point we were planning to pass the bootloader information
with custom atags that did not work out too well.
There's no need for these any longer as the kernel has been booting
fine without them for quite some time. And Now we have device tree
support that can be used instead.

Currently omap onenand driver invokes gpmc_cs_request, obtains address
space allocated by gpmc to onenand. Remove this, instead use resource
structure; this is now updated with address space for onenand by gpmc
initialization with the help of gpmc_cs_request. And remove usage of
gpmc_cs_request in onenand driver.
This helps in smooth migration of gpmc to driver.

Some of them are pretty good catches, such as gpio.c:56 and
usb-tusb6010.c:129.
Thanks to Jarkko Nikula for some comments on the sscanf() warnings.
It seems that the kernel sscanf() ignores the field width anyway for the
%d format, so those changes have been dropped from this second version.
Thanks to Daniel Marjamäki <daniel.marjamaki@gmail.com> for pointing
out that a variable was unnecessarily marked static in the
board-omap3evm.c change.

This is needed to minimize io.h so the SoC specific io.h
for ARMs can removed.
Note that minimal driver changes for DSS and RNG are needed to
include cpu.h for SoC detection macros.

The calculations done with sync_clk are anyway in picoseconds
and switching to picoseconds allows sync_clk values that are
not a whole number of nanoseconds - which is sometimes the
case.

Move the remaining headers under plat-omap/include/mach

files using these headers to include using the right path.
This was done with:
#!/bin/bash

plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)

drivers/video/omap \
sound/soc/omap"
other_files="drivers/leds/leds-ams-delta.c \
drivers/mfd/menelaus.c \
drivers/mfd/twl4030-core.c \
drivers/mtd/nand/ams-delta.c"
for header in $headers; do
old="#include <mach\/$header"
new="#include <plat\/$header"
for dir in $omap_dirs; do
find $dir -type f -name \*.[chS] | \
xargs sed -i "s/$old/$new/"
done
find drivers/ -type f -name \*omap*.[chS] | \

for header in $(ls $mach_dir_old/*.h); do

Add generic onenand support when connected to GPMC and make the
boards to use it.
The patch has been modified to make it more generic to support all
the boards with GPMC. The patch also remove unused prototype for
omap2_onenand_rephase(void).
Note that board-apollon.c is currently using the MTD_ONENAND_GENERIC
and setting the GPMC timings in the bootloader. Setting the GPMC
timings in the bootloader will not allow supporting frequency
scaling for the onenand source clock.
