The use of S3C2410_GP[A-Z]x_INP and S3C2410_GP[A-Z]x_OUTP are
very rare and are taking up large amounts of space in the
regs-gpio.h header.
The GPIO layer has had generic input and out defines called
S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work
for all S3C24XX GPIOs.
Do the following replacements:
S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT
S3C2410_GP[A-Z][0-9]*_\INP => /S3C2410_GPIO_INPUT
S3C2410_GPA[0-9]*_OUT => S3C2410_GPIO_OUTPUT
to remove any usages of these and prepare the header for

Move the GPIO suspend/resume support inline with the gpiolib support
so that it will work with both the S3C24XX and S3C64XX series.
The s3c_gpio_chip is extended to have a pm callback and a save block
to keep the state of the GPIO over suspend, and the code from the
s3c24xx implementation is added to a new common file.
The suspend process now uses the list of registered chips to go through
saving and restoring each one as appropriate, using the pm callback to
select the appropriate routine depending on the type of control register
present.
This change also means that any additional GPIO added should not require
changes to the PM.

OMAP wishes to pass state to the boot loader upon reboot in order to

already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().
This patch fixes things to pass this string to arch_reset(). This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the

We need to add plat-s3c to the build to get the headers
that will go in here once moved from include/asm-arm so
we may as well put some useful common s3c code in here
to stop the errors generated form having nothing built.
The cpu setup is now passed the cpu idcode and the table
of supported cpus to s3c_init_cpu() to abstract the
cpu identification out of the initial io setup.
As well as moving the cpu initialisation code, we move the
map of the board specific items up to the calling code as
none of the map_io() functions actually do anything other
than pass this to iotable_init().
This patch does not rename any of the init functions that
will be common to s3c24xx and any other s3c architectures
as this can be done at a later date as it will touch all
the board support files which use functions such as
s3c24xx_init_clocks() and s3c24xx_init_uarts().
Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h

board initialisation functions. This means that each board
has definitions specific to the cpu support included and
